Abstract: System and method for dynamic loading of remote classes. Using embodiments, remote classes may be loaded dynamically by a default class loader without the use of separate, custom class loaders. The remote class loader mechanism may locate on remote systems classes needed by code executing on the local system but not locally stored, and which therefore cannot be located and loaded by the default class loader. After locating the classes, the remote class loader mechanism may obtain copies of the classes and save them to a location indicated by the class path of the default class loader. The default class loader can then locate and load the classes from the location indicated by the class path.

Abstract: In a computer system, a method for automatically registering resources required for an application program module to execute. After the application program module is booted, a registration cache is examined to determine its status. The registration cache is stored in association with the application program module and it indicates whether a registry on the computer system needs to be updated, such as after the user has moved files or renamed files such that registry keys in the registry may no longer be valid. If the registration cache indicates that the registry needs to be updated, then a search is made through a predetermined directory, such as the application program module folder. The search is looking for an application file or a dynamic link library file. Upon detecting an application file or a dynamic link library file, then a resource fork in association with the file is opened and it is determined whether there is a self-registration resource in the resource fork.

Abstract: A method and system for implementing an application on a computer system, in particular a portable computer system, by binding an interface (e.g., a function call and required address translations) in the application to a specific memory address. The application is installed on the computer system with a reference to a section of computer code. The reference is for transferring execution of the application to that section of computer code. After a specified criterion is satisfied, the reference is replaced with a specific memory address of the computer system's memory map, such as a line number, thus binding the application to that memory address for that function call. Accordingly, when the application makes a call to that function, the execution of the application can proceed directly to the line number where that function is located.

Abstract: A system and method for managing network devices. The framework may provide a suitable system for managed object data type conversions between various data description languages, such as an interface definition language (e.g., OMG IDL) and an abstract syntax notation (e.g., ASN1). This conversion facility may be used in both request and event network traffic, so common libraries may be used. Two separate libraries may be used: a converter framework library and a converter implementation library. The framework library provides a collection classes that may be used by the clients of the converter libraries. Most classes in the converter framework library are handle classes (or wrappers) to the real implementation (or body) classes in the converter implementation library. Framework classes hide the details of the real implementation classes and provide a simple, consistent interface to any data type converter via IDL.

The internal information is removed from the modified constant pool after linking.

Abstract: A Plug-in equipped updateable firmware includes a number of value added software or “plug-in” modules stored in association with a firmware module within a non-volatile memory device, such as FLASH. In one embodiment, the plug-in and firmware modules are stored in a compressed form within the FLASH, whereupon during boot-up they are extracted into random access memory (RAM). The firmware is extracted into the RAM at a predetermined memory address, whereas each plug-in is extracted into the RAM at a re-allocable memory address. In one embodiment, the memory address associated with each extracted plug-in is stored in a table for reference by the firmware. When the firmware calls a function of a plug-in stored within RAM, the firmware references the table to locate the memory address for the extracted plug-in, and initialization code within the plug-in returns to the firmware a pointer to the function.

Abstract: Apparatus and methods are provided for improving devirtualization of method calls. The apparatus and methods reduce the amount of processing time used in performing lookups of methods by limiting such lookups to calls of methods that have been either overridden or overloaded. If a method has not been overridden or overloaded, a branch to the compiled method code is directly taken. If a method has been overridden or overloaded, a lookup routine is executed for looking-up the appropriate method to be invoked on the passed object. The identification of whether to use a lookup routine may be performed in many different ways including providing an extra field in a method block of the method, inserting code into a prolog of the method, and the like.

Abstract: Presented herein is a video enhancer plug-in for a web browser that may either interface directly with the browser or indirectly as a plug-in for another more general multimedia browser plug-in. The video enhancer consists primarily of video enhanced scripts and a library of specialized routines. A script is intended to provide a visually interesting display within a web browser environment and calls upon routines in the library to do so. These routines, for example, may take live video input from a video camera and perform specific functions such as locating the head of an individual within the camera's field of view. Because the script runs within a web browser, it allows components of the system to be widely separated from one another, so long as they are connected across a wide area network such as the Internet.

Abstract: For a given set of programs and their related DLLs the following tool and method finds the minimum set of DLLs for which to apply demand loading and quantifies a lower bound on the expected performance improvement that comes from applying demand loading to the identified set of DLLs. Additionally, the tool and method identifies the set of DLLs in which demand loading cannot be applied because of data exports, but which might benefit from demand loading.

Abstract: A method, computer program, signal transmission, apparatus and system verify instructions in a module of a computer program to be dynamically linked with at least one other module. First it is determined whether checking an instruction in a first module which is loaded requires a lowest upper bound (LUB) class of at least two referenced classes in one or more referenced modules different than the first module. If such information is required, a constraint for the referenced module is written without loading the referenced module. The constraint is of the form “the set of at least two classes inherits from a specified class.

Abstract: A method is provided for determining an identity of a browser in an Java environment in which an intermediary program masks the browser's identity. The method begins by querying an operating system process table for information identifying the browser. Thereafter, a Java properties table including the information from the process table is set. In response to a request from a calling program (e.g., an applet class) for the browser identity, a getProperty method is then called to retrieve the browser identity from the properties table. The browser identity is then returned to the calling program.

Abstract: An improved system and method for loading and linking a dynamic link library (DLL) for use of its entities by an application program. During design, implementation, and production implicit linkage is assumed. Upon load and execution by the computer operating system, explicit linking is assumed resulting in unresolved external references. During execution, the application program invokes DLL loading and linking routines to resolve these external references within the application program's memory space. The application program continues execution and seamlessly invokes DLL entities.

Abstract: A method of reducing interference among applications co-located in a process when using dynamic libraries is disclosed. For each dynamic library, multiple instances of the dynamic library are loaded in the same operating system process (or process), whereas each instance of the dynamic library corresponds to one of the multiple applications co-located in the same process. In particular, the text segments (or read-only segments) of the instances of the dynamic library are mapped to the same physical memory pages, leading to a low memory footprint. Moreover, within the process, a co-located application's access to a dynamic library is directed to the instance (of the dynamic library) associated with the accessing application, reducing interference among applications co-located in the same process.

Abstract: The invention describes a methodology and a system for dynamically specifying exceptions and exception handlers for an application written in any computer language, which has exception handling facility. The methodology described in this invention decouples the exception handling logic from the application thereby can be used to alter the behavior of the program/module/application as well as to define new types of exceptions at runtime. The decoupling of the exception handler logic eliminates the language dependence of the application and further helps in customizing the behavior of the application when they are being deployed in new environments. Moreover dynamic exception handling is not operating system dependent.

Abstract: A method of Web-site host consistency administration provides for consistent presentation of data despite presentation on client machines with inconsistent software-object libraries. The host sends screen images which contact the client's onboard DLLs as little as possible. That way, inconsistency problems called binary incompatibilities are avoided. The client is excused from most of the processing load. The client's role is practically limited to displaying the received screens and sending out keystrokes and cursor-moving device inputs. The light role given the client correspondingly shifts more of a load on server-side processing and data storage. Nevertheless, the method provides high assurance the any client sees substantially the same result for the same request despite differences or inconsistencies in software-object libraries onboard the client's machine.

Abstract: A SIM Manager is disclosed that accesses functionality contained within a GSM-type telephone SIM by combining functionality of a plurality of asynchronous RIL functions into a single synchronous application programming interface. A first dynamic link library receives a function call for performing a selected function from an application operating in a GSM-type telephone device. The first dynamic link library is preferably a stub dynamic link library to which applications link, links to the application and initiates a process thread corresponding to the received function call, thereby blocking all subsequently received calls until the received function call for the selected function is complete. A second dynamic link library contains at least one application programming interface corresponding to the selected function.

Abstract: The present invention provides a system of objects and program components wherein an object accesses different associated program components for different implementations of a corresponding function of the object. The system comprises: a first object having one or more functions; a first program component having one or more functions, the first program component being dynamically linked to the first object at a run-time of the first object; and wherein the first object access the first program component using a function call which may result in the access to a second program component having one or more functions.

Abstract: A system and method for altering the operation of a computer application while avoiding recompiling the computer application or modifying the kernel associated with the operating system of a computing device. A computer application is launched in a suspended mode. An asynchronous procedure call (APC) is used to load an additional dynamic link library (DLL) to be associated with the computer application. The additional DLL includes routines that operate differently than routines originally associated with the computer application through an initial DLL. The references to the routines within the computer application are redirected to the routines of the additional (DLL). The operation of the computer application is therefore changed while avoiding rewriting the application or changing the operating system.

Abstract: A method and system is provided for creating applications for one or more types of programmable logic controllers (PLCs). A open development kit (OKD) is provided that permits dynamic link libraries to be created and interfaced to a user application software and also to the interface layers of the various types of PLCs. The types of PLCs may include soft PLCs, slot PLCs, and hard PLCs and interface via slots of a personal computer platform. The ODK provides generic interfacing to the various types of PLCs and establishes the necessary operating environment structure to implement processing in either a non-real time and a real time mode. A single application package may then control and manage the various types of PLCs. Communication paths are provided from the PLCs to the ODK subsystem to the user application so that the application software is essentially indifferent to type of PLC involved.

Abstract: Intercepting calls to document production functions. In one embodiment of the application, an import address table for the application is accessed, document production functions being supplied by an operating system are identified within the import address table. For each identified document production function, an address associated with that function in the import address table is replaced with an address to be used to access a proxy document production function. In another embodiment, the application is loaded in debugging mode. Once the import address table for the application has been populated with addresses for functions called by the application, the execution of the application is paused. An address, in the import address table, associated with a document production function to which calls from the application are to be intercepted is replaced with an address to be used to access a proxy document production function. Execution of the application is then resumed.

Abstract: The invention is directed toward a loadable interprocess communication manager and generally to a computer operating system capable of supporting plural threads running in a computer having a working memory, the computer operating system including a kernel resident in the working memory at link time and a loadable interprocess communication manager resident at link time outside of the working memory and dynamically loadable into the working memory at run time upon request by one of the threads in one address space to communicate with an other thread in an other address space. The kernel includes a loader for loading the interprocess communication manager into the working memory in response to the request by the one thread. The computer further includes a storage memory separate from the working memory, the loadable interprocess communication manager residing at link time in the storage memory. The loader loads the interprocess communication manager from the storage memory to the working memory.

Abstract: Systems and methods for providing a universal print assist in a printer environment. A print assist is provided as a separate component from a print processor and spooler to enable a selective intercept and performance of an action (e.g., to modify, split, merge, redirect, gather or register information or otherwise alter or make observation of a print data stream) on the print data stream as the data stream is despooled by the spooler or print processor to a print provider without customizing any pre-existing components. The print assist uses a method whereby the print assist is bound to the output interface between the spooler and/or print processor and the print provider. Accordingly, the despooled print data stream passes through the print assist as it is despooled from the spooler or the print processor to the print provider. And, since the print assist is a separate component, the print assist may be used with any customized print processor and/or spooler to provide a universal print assist solution.

Abstract: Techniques for developing and exchanging virtual machine implementations and/or support library implementations are described. In one embodiment, the virtual machine design specifies a set of functions for executing all or substantially all support library operations that are dependent on the implementation of the virtual machine. When a developer desires to substitute one virtual machine implementation for another, the developer is able to basically “plug-in” the second virtual machine implementation with minimal impact on the support libraries since both virtual machine implementations provide implementations for the set of specified functions that are dependent on the implementation of the respective virtual machine. Conversely, different support libraries may be utilized in conjunction with a particular virtual machine implementation.

Abstract: A method for optimizing an object file is described. The method includes simulating execution of an object file, where the object file includes a control transfer instruction having an undefined target, and modifying the object file to include an address space bridge section, where the address space bridge section is configured to define the undefined target. When the newly optimized object file is executed, the address space bridge is invoked and the target is mapped in memory in an original address space.

Abstract: A data representation is read and parsed. A declaration referencing an executable namespace is recognized. An expression is recognized. A name (declared within the executable namespace) within the expression having zero or more additional data representations is also recognized. In response, functions corresponding to the name and additional data representations are recursively resolved, and caused to be invoked and executed, with the execution results of the inner functions successively provided for use in the execution of the outer functions. For each function, the function or a creator to create the function is instantiated. The instantiating is effectuated by following a path enumerated in the declaration for locating functions of the namespace. If a creator of the function is located and instantiated, the function is created using the function creator, and then the created function is instantiated. Upon instantiation, the referenced function is invoked and executed.
