  • Patent number: 6405263
    Abstract: A method and apparatus for subclassing System Object Model (SOM) class objects for a dynamic object-oriented language. A proxy class object is created using the dynamic language that points to the SOM class object. Next, a dynamic language subclass is created. This is followed by the creation of a SOM class object using the SOM interface, which causes certain SOM methods to be overridden by dynamic language redispatch stubs. The dynamic language overrides the SOM dispatch procedures and replaces the dispatcher with its own procedures. The new dispatch procedure will search for a method in the dynamic language class object method table first in response to a message, and if not found, redirects the message to the SOM environment.

  • Patent number: 6389483
    Abstract: A technique for enhancing the modifiability and reuse of telecommunications software systems is described. The problem domain is first partitioned into tasks that are assigned to distinct software program modules. In one embodiment, each of the software modules have multiple output ports. Each output port provides a mechanism to link the software module to a specific version of a different program module. The multiple output ports are used to selectively link the module to one of several versions of a different program module. The linking is performed as early as system design time or as late as run-time, or at any intermediate time between the two. The use of output ports makes software modules less dependent on each other and also simplifies the “hot-swapping” or dynamic replacement of one module by another at run-time. In an alternative embodiment, each of the software modules has a unitary output port where each output port comprises an array of linking records.

  • Patent number: 6363435
    Abstract: A single object functions as a centralized monitoring point for events fired in a hierarchical object model. Objects within the hierarchy register with the event monitoring object when they are created. These objects then route their events to the event monitoring object. A listening object also registers with the event monitoring object to receive notification upon the occurrence of certain events within the hierarchy. A property of the event monitoring object corresponding to a particular class of object is parameterized with an identifier that designates the events to be sourced to the listening object The event monitoring object couples the listening object to a filter object that sources only events designated by the parameterized property. The event monitoring creates the filter objects as needed. A filter object can report events to more than one listening object if the listening objects register to be notified of the same events.

  • Patent number: 6363433
    Abstract: A method and mechanism for handling the execution of extensions on a client machine, such as ISAPI applications written for a server. When a local browser is notified that an extension is local, the browser creates a moniker for interfacing with the extension. Although local, the moniker appears to the extension to be a server process, whereby the extension executes its function on user data and provides a result to the moniker. The moniker returns the result to the browser for display thereof. The method and mechanism enable extensions developed for remote servers to be locally executed in a client machine, while using the local browser as a user interface.

  • Patent number: 6345312
    Abstract: A technique for selectively dummying a data pipe transparent to a writer application is provided. A writer application writes data to a local data pipe or a cross-system data pipe and one or more reader applications read data from the data pipe. The technique involves determining when a last reader application of the at least one or more reader applications closes the data pipe before the writer application has completed writing data to the data pipe. Upon determining this condition, further writing of data to the data pipe by the writer application is transparently prevented. While transparently preventing writing to a dummied data pipe, writing of data to a fitting, e.g., for a permanent record, can proceed.

  • Patent number: 6343308
    Abstract: Methods, systems and computer program products execute an application within a first version of a runtime system, wherein the application includes at least one call to an object class of a second version of the runtime system. An application, including object classes called by the application, is loaded into a first version of the runtime system. A class interface having at least one identifier for at least one respective object class of a second runtime system version called by the application is loaded into the first version of the runtime system. The application is then executed within the first version of the runtime system without causing an error condition by any of the calls to the second runtime system version object classes named in the class interface. Calls to object classes of the second runtime system version not identified within the downloaded class interface are not allowed.

  • Patent number: 6324589
    Abstract: A server for use in a client/server computing system for processing a transaction, the client/server computing system being of at least a three-tier process type, where a first tier process initiates the transaction and contacts a second tier process to further the transaction which in turn contacts a third tier process which contains local data to be updated in the transaction, the server, which runs the second tier process, has a means for receiving a transaction context from the first tier process requesting that the second tier process be registered in the transaction; and a means for passing on the transaction context to the third tier process informing the third tier process that it should register itself into the transaction directly with the first tier process without going through the second tier process. This greatly reduces the required number of cross-process flows.

  • Patent number: 6091896
    Abstract: A software development system with improved facilities for debugging optimized code. Certain parts of the operations specified by source statements are categorized as "data change points". A compiler 102 identifies the correspondence between the machine instructions that perform data change point operations and the source statements from which these machine instructions were derived and stores this mapping data 110 for use by a debugger program 104. This source code/machine instruction mapping data is used by the debugger to permit users to specify machine instruction locations (such as for setting breakpoints) by identifying a source statement and specifying that the debugger use the data change point of that statement; as another example, the step command includes an option that permits a user to continue execution until the next data change point instruction is reached. The debugger's source code display (FIGS.

  • Patent number: 5903754
    Abstract: The present invention provides a method and system for dynamically building a protocol stack for use by a communication program to establish a data transfer protocol. The method of creating the protocol stack first establishes a set of protocol layer descriptions. One protocol layer description is used to establish an initial protocol layer that has a protocol interface. For each other protocol layer description, a current protocol layer having an interface is established using the protocol layer description, and the current protocol layer is connected to a previously established protocol layer using one of the interfaces from the previously established protocol layer. In this manner, the protocol layers are connected in pairs. These connected protocol layers make up a protocol stack. Finally, the method provides the interface from a protocol layer, e.g., the top layer, to the communication program.

  • Patent number: 5887169
    Abstract: A technique for enhancing a software layer while ensuring backwards compatibility is disclosed. In one implementation, the software layer is a hardware abstraction layer (HAL) that interfaces between hardware and an operating system of a computer system. The HAL can be enhanced with additional functionality without having to worry about crashing the operating system when the particular HAL in use with the computer system lacks the additional functionality. Hence, the inventive technique allows enhancements to the HAL to be made without causing any backwards compatible problems.
