Abstract: A method of providing tailored add-on applications to an underlying foundational software suite that frequently receives updated versions that would otherwise overwrite changes in the foundational software that are required by the tailored add-on. Instead of functional changes to the foundation, the tailored add-on makes a fairly uniform and simple change in the place of each needed change, by inserting a call to an add-in definition object. The add-in definition object then contains code for performing the functionality needed by the add-on application. The add-in definition object is down-ported to all supported versions of the foundational software. The calls of the add-in definition object are integrated into the foundational software in a way which minimizes conflicts, allows for concurrent implementation while maintaining a clear separation between foundational code and modified code, and minimizes ongoing maintenance development of the add-on application's conflicts with the foundational application.

Abstract: A general purpose high-performance distributed execution engine can be used by developers to deploy large-scale distributed applications. To allow developers to easily make use of the distributed execution engine, a graph building language is proposed that enables developers to efficiently create graphs (e.g., direct acyclic graphs) that describe the subprograms to be executed and the flow of data between them. A job manager (or other appropriate entity) reads the description of the graph created with the graph building language, builds the graph based on that description, and intelligently distributes the subprograms according to the graph so that system resources are used efficiently. In one embodiment, the graph building language (and, thus, the description of the graph) includes syntax for replication, pointwise connect, cross connect and merge.

Abstract: Computer method and apparatus provides lightweight stereotypes in a programming model. An alternative to applied profiles is disclosed. A keyword list or list of strings is recorded as an annotation to a model element. The keywords are indicative of applied stereotypes of the model element, where the stereotypes are empty or are used as labels. The list of strings effectively augments the collection of applied stereotypes of the model element.

Abstract: Leveraging profiles to define stereotypes for other profiles introduces efficiency into modeling. Although constraints can be inherited, constraints cannot currently be aggregated across profiles. Aggregating constraints across profiles leverages the labor invested in defining other profiles as well as adding flexibility to defining stereotypes.

Abstract: One embodiment of the present invention provides a system that determines whether a data structure, such as an array, is modifiable. First, the system loads a source file for a class. The system then examines the source file to identify a set of data structures in the class, and uses escape analysis to determine whether each data structure is modifiable. The system then performs an action based on the determination. In a variation on this embodiment, if the data structure is not determined to be modifiable, performing the action involves storing the data structure in a read-only memory (ROM) instead of a random-access memory (RAM), which leaves more RAM available for other purposes.

Abstract: Computer implemented method, system and computer usable program code for processing a data object, for example, for searching for, creating or updating a data object. A computer implemented method for processing a data object includes receiving a request for the data object. A static portion and a dynamic portion for the data object are determined, and an instruction for the static portion and an instruction for the dynamic portion are processed separately. To search for a data object, a result from processing an instruction for the static portion and a result from processing the instruction for the dynamic portion are merged to form a hybrid data object. To create or update a data object, a result from processing an instruction for the static portion and a result from processing the instruction for the dynamic portion is saved in a database.

The extension could apply to an entire object type, or to a specific state within the object. Annotations that can be added to the extension include @Accessable, @Gettable and @Settable. In one embodiment, a method selectively accesses one or more object states. The method includes generating an annotated extension identifying each internal object state to be exposed for access, adding a usage annotation to the extension that defines an accessor method associated with each identified state, and operating a virtual machine to call the accessor method associated with a particular identified state. The particular state may then be accessed, as defined by the called accessor method.

Abstract: A method for automating updates to configuration data includes coding a builder method within a source file for an application component and running the source file through a transformer engine configured to implement an interface within the source file. The builder method is implemented to construct an in-memory data structure representing one or more configuration data elements of a configuration object provided by a configuration service for the application component. The interface provides a mapping between one or more configuration data elements represented in the in-memory data structure and one or more corresponding data elements of a listener object representing changes to the configuration object. The mapping is implemented to update the in-memory data structure at runtime whenever a change to the configuration object is signaled to the listener object.

Abstract: The present invention relates to an XML application framework (XAF). XAF applications are data driven such that all operations with the computer system are data focused. In addition, the components used in the XAF application are instantiated and connected according to how the data is displayed and what type of data is used. Applications within XAF comprise a user interface (UI) connector, an action module, and a data connector. UI connectors receive UI events and connect the UI event to an action module. The action module generates a standard format action from the UI event and sends it to the data connector. The data connector translates the standard format action into a data-specific action that changes data in a data store. A data connector then sends a standard format data representation corresponding to the changed data back to the UI connector to provide the changed data to the UI.
