Abstract: Methods, systems, and articles of manufacture consistent with the present invention limit access to parts of a shared software library by using a class loader that generates a selective interface between an external process and a program file (such as a class definition) in the shared library. This prevents external processes from loading parts of the shared library that were meant to remain private or internal to the library. Methods, systems, and articles of manufacture consistent with the present invention load a program file, such as a class definition, from the shared library and generate an interface (such as an object) to the loaded program file. A determination of whether the program file can be exported is performed based upon a status indicator associated with the interface. The interface limits access to the program file if it is determined that the program file cannot be exported.

Abstract: Methods, apparatus, and computer program products are disclosed for a process of dynamically adding new software having resource controls to an operating system and having the resource controls added to various resource control files in the operating system. The process also allows for a resource control to have an arbitrary number of limit values before a highest limit value is reached. A method of dynamically checking a resource control associated with newly added software to an operating system is described. A process or other type of entity in the operating system encounters newly added software and its associated resource control. The operating system then determines whether the resource associated with the resource control is active. If so, the operating system then determines whether usage of the resource by the entity exceeds a limiting value stored in the resource control. If so, one or more actions related to the resource are triggered by the operating system.

Abstract: A system and method are provided for transferring a packet received from a network to a host computer according to an operation code associated with the packet. A packet received at a network interface is parsed to retrieve information from a header portion of the packet. A flow key is generated for a received packet that was formatted with one of a set of predetermined protocols. A packet's flow key identifies a communication flow that comprises the packet. Based on some of the retrieved information, a code is associated with the packet to inform a transfer engine how the packet should be transferred to host memory. Based on a packet's code, the transfer engine stores the packet in one or more host memory buffers. If the packet was formatted with one of the set of predetermined protocols, its data is re-assembled in a re-assembly buffer with data from other packets in the same communication flow. Re-assembled data may be provided to a destination application or user through page flipping.

Abstract: An automatic and parameterized compute implemented method for transposing wires in an integrated circuit design can y bus lines with similar impedances, and therefore similar signal transmission characteristics. Using a specially designed CAD tool, a user can specify a transposing porn, intervals at which to transpose wires, and a metal layer through which to accomplish the transposing in the integrated circuit. Using a routing database the tool then automatically determines the locations in the design where transposing needs to be performed, re-routes the wires being transposed while optimizing the circuit design space being used, and re-routes (or causes the re-route of) any other wires affected by the transposing process. The result is a new version of the routing database reflecting transposition, but with no change to the circuit's netlist.

Abstract: A database system wherein one or more entry databases store a plurality of entries. Each entry is of a given type that defines the fields of the entry. Each field contains or identifies an object with associated attributes or data. The type of each entry may further define behavior in the form of methods the entry can implement. An entry type which is a subtype of another inherits all fields and behavior of its super-type, and contains additional fields and/or defines new/modified behavior. Entries may be expressed in a Java™ programming language. The database system may further employ a search engine which allows queries to be made upon entries in the database. In one implementation, the queries include a read operation, a take operation, and a notify operation. Each query request includes a command indicating the type of operation, and a template which is an entry object having some or all of its fields set to specific values that must be matched exactly.

Abstract: Meta object facility repository event notification may be accomplished through the use of listener interfaces implemented by event listeners and event source interfaces implemented by objects at the repository. The listeners may register for event notifications of a particular type by passing a registration call for the event type to an appropriate event source interface. Additionally, listeners may register for listening to event notifications of any combination of event sub-types by passing a registration call (together with a bitmask indicating the event sub-types combinations) to a combination event type source interface. If an event occurs, an event object (describing the occurred event) is created by the event source and then it is passed via a notification call to each of the listeners registered for notifications of this particular event type or sub-type. This provides notification of the occurrence of events to the listeners.

Abstract: A program interpreter for computer programs written in a bytecode language, which uses a restricted set of data type specific bytecodes. The interpreter, prior to executing any bytecode program, executes a bytecode program verifier procedure that verifies the integrity of a specified program by identifying any bytecode instruction that would process data of the wrong type for such a bytecode and any bytecode instruction sequences in the specified program that would cause underflow or overflow of the operand stack. If the program verifier finds any instructions that violate predefined stack usage and data type usage restrictions, execution of the program by the interpreter is prevented. After pre-processing of the program by the verifier, if no program faults were found, the interpreter executes the program without performing operand stack overflow and underflow checks and without performing data type checks on operands stored in operand stack. As a result, program execution speed is greatly improved.

Abstract: A remote terminal emulator (RTE) is provided in which substantially all of the time elapsing during an emulated use of a computer system under test is categorized and reported. The time required by the computer system under test to respond to command signals transmitted by the RTE is recorded as a receive time and is measured from completion of the transmission of the command signals to recognition of a pattern specified by the RTE as signifying completion of the response by the computer system under test. As a result, the receive time recorded reflects the time required by the computer system under test to (a) process and carry out the command transmitted by the RTE and (b) transmit response data back to the RTE.
