A method and apparatus for the specification and automatic generation of user interfaces of information system (computer programs) is provided. The method is based in pattern language to specify requirements in an un-ambiguous mode and with precise semantics. The pattern language allows a user interface model to be composed using elements of the pattern language (computer objects in the object oriented programming style) which fully specify the desired user interface. The semantics of the objects in the user interface model have one and only one definition such that user interface model can be validated in a validation process. The validation process eliminates bugs in the final computer program code which is automatically produced from the user interface model. A model (metamodel), an editor tool (computer program) implementing the model for creating specifications of the user interface model, DTD specification, code generators, and other artifacts are depicted and described here for obtaining such user interfaces for different platforms (computers and operating systems) and different programming languages without manual coding of the computer code to implement the user interface. The software obtained is ready to run and it is able to communicate with a business server component using a standardized Application Programmatic Interface (API).

Modern enterprises have multiple dissimilar data stores. Collectively, the enterprise data stores store a set of enterprise data objects, typically in multiple dissimilar formats. An object-oriented heterogeneous data store interface (HDSI) for interacting with such enterprise data stores and data objects is described. The HDSI may include a query component, a data store component and a provider interface that specifies a query behavior with a query component parameter. For each type of data store, there may be a provider plug-in to the HDSI. Each provider plug-in may include provider components that conform to the provider interface. The HDSI may further include data store object components corresponding to data objects stored in the data stores. A data store object design GUI may be utilized to build graphical representations of data objects. A data store object source code generator may generate object-oriented programming language source code for each data store object component.

A computer implemented system and method for managing mobile workers in an object oriented programming environment is disclosed. A plurality of target objects that correspond to facilities assets to be worked on by a mobile worker are classified within a database of the computer. The attributes of each target object are defined, including a task to be performed on each target object. Mobile workers are scheduled for the tasks to be performed on target objects by running a rule engine to determine the algorithms and heuristics to be used to schedule mobile workers for the tasks to be performed. The scheduled jobs are then output to the mobile workers.

The present invention is directed to a system, method and instructions for handling path flow exception and finalization processing in an object oriented programming language. Initially, each instrumentation method is checked for a code to indicated an exception being thrown. A hook is inserted before the exception code and identifies the method throwing the exception. Methods must also be checked for exception tables. When an exception table is found, then a hook is inserted at the entry point of each exception handler for every entry in the exception table. This hook identifies the method which catches the exception.

A method, apparatus, and article of manufacture for accessing a database. A hierarchical database system is modeled into an objects framework, wherein the objects framework corresponds to one or more application views, database definitions, and data defined and stored in the hierarchical database system. The objects framework also provides mechanisms for accessing a relational database system, wherein the objects framework provides industry-standard interfaces for attachment to the relational database system. Transactions from an application program for both the hierarchical database system and the relational database system are processed through the objects framework using message queue objects.

In a system for remotely monitoring networked devices and appliances, email messages are sent across networks, the email messages containing configuration, status or other information. For flexibility, it is desirable to quickly and easily change the message type designation, and to easily determine a data structure definition appropriate for storing the received information. To achieve this goal, the message type designation of a given message's information may be defined within the message itself, and extracted at the receiving end before the information is analyzed or stored according to a data structure definition determined by the message type designation. A large number of devices can thus communicate configuration, status and/or other types of information in a variety of message types. A method stores information concerning a remotely monitored device, the information being contained in a message that includes a message type designation. The method involves extracting the message type designation from the message, determining a data structure definition based on the message type designation, reading data elements from the message, and storing the data elements into a database according to the data structure definition. The method may be implemented in object-oriented programming, in a software module including a data retriever class and a database interface class.

A framework for use with object-oriented programming systems provides a software build system that detects modules that make up a software product, examines each module to determine if it is up-to-date, and automatically updates any modules that require processing. The framework includes a software object of a class called "Product" that comprises a software product to be processed and built. An instance of the Product is comprised of multiple software build objects, each of which is called "Object". Each Object in turn contains four objects that are a kind of object class called BldSrc (Build Source). The BldSrc objects specify a different aspect of the software product and desired processing. Each of the software build objects in a Product's Object list is examined to determine if all four of the BldSrc objects is current. If any one of the software build objects is not current, the Object is re-built. If all four objects are current, the re-building step is skipped. In this way, each of the software build Objects making up a Product is automatically examined and processed, and the Product is produced.

A system and method for detecting the mutability of fields and classes in an arbitrary program component written in an object oriented programming language is disclosed. A variable is considered to be mutable if a new value is stored into it, as well as if any of its reachable variables are mutable. The system and method uses a static analysis algorithm which can be applied to any software component rather than whole programs. The analysis classifies fields and classes as either mutable or immutable. In order to facilitate open-world analysis, the algorithm identifies situations that expose variables to potential modification by code outside the component, as well as situations where variables are modified by the analyzed code. An implementation of the analysis is presented which focuses on detecting mutability of class variables, so as to avoid isolation problems. The implementation incorporates intra- and inter-procedural data-flow analyses and is shown to be highly scalable. Experimental results demonstrate the effectiveness of the algorithms.

A method and apparatus, including a computer program apparatus, implementing techniques for generating a report from a technical computing environment provided by a mathematical computer program. A report generator defines a set of reporting components that can be assembled to form a report template and processes the reporting components of the report template in order to extract data from the mathematical computing environment and generate the report. The report generator includes a user interface by which a designer can hierarchically assemble the reporting elements, which are defined according to an object-oriented programming language. The report generator bi-directionally communicates with the mathematical computing environment such that the report generator can evaluate expressions defined within the mathematical computing environment, change initial conditions and parameters of a mathematical model, and issue commands to advance the simulation time of the model. The report generator includes a generation engine that generates an intermediate representation of the report and a transformation engine that transforms the intermediate representation into an electronic document according to a user-selected format.

A framework for use with object-oriented programming systems provides a reusable object oriented (OO) framework for use with object oriented programming systems that provides an information retrieval (IR) shell that permits a framework user to define an index class that includes word index objects and provides an extensible information retrieval system that evaluates a user query by comparing information contained in the user query with information contained in the word index objects that relates to stored documents. The information in word index objects is produced by preprocessing operations on documents such that the documents relevant to the user query will be identified, thereby providing a query result. The information retrieval system user can load documents into the computer system storage, index documents so their information can be subject to a query search, and request query evaluation to identify and retrieve documents most closely related to the subject matter of a user query.

A method of processing a query in a system in an object oriented programming environment, includes using a code to create a condition filter in a standard query language statement, the condition filter defining properties to be satisfied by a result of the query, and the condition filter using an object to execute a precompiled query language statement, and sending the standard query language statement to a database.

Aspects of the invention can be used to enhance a user's instant messaging experience through the ability to involve a large number of users in a variety of different interactive environments while maintaining inter-user responsiveness. The scalability aspect of the invention utilizes scalable messaging interfaces and object oriented programming to extend user limits beyond current boundaries. The portability of this implementation and programming language also enables users of different devices such as PDAs, personal computers and mobile phones to use the same software and architecture to communicate with other users. Aspects of the invention further enable content providers to advertise, poll and otherwise interact with a large audience in a real-time instant messaging environment.

A system and method for instantiating an interface or abstract class in application code are provided. An object-oriented programming language is extended such that interfaces and abstract classes can be instantiated in application code without a concrete class specified. Metadata is defined which maps each interface or abstract class instantiation in the application code to a concrete class to be used either by the compiler at build time, or the virtual machine at runtime. Once the appropriate concrete class is determined from the metadata, the class is instantiated with a conventional class loader. The metadata may be provided, for example, as a separate file, such as a markup language file, defined with a virtual machine switch, as annotations in the application code, or the like.

An apparatus and method for universal programming language conversion between two different sequential programming languages, e.g., sequential procedural and sequential object oriented programming languages. In particular, conversion is between a source program in a first programming language and a target program in a second programming language. Initially, the source program in the first programming language is parsed using a parsing interface specific to the first programming language. All syntax from the parsed source program is then stripped or removed. Classes in a framework are instantiated to capture semantics of the parsed source program independent of syntax and execution model of the sequential programming languages. The classes are C++ classes representing fundamental core constructs of all sequential programming languages. A semantic representation of the parsed source program without any syntax is produced. The semantic representation is received at a printer interface specific to the second programming language and syntax of the target program in the second programming language is added. This same process can be used for either high-level conversion or compilation depending on whether the target programming language is high level or low level, respectively.

An extension of object-oriented programming languages enables the use of replaceable classes and virtual constructors, thereby allowing existing code that creates objects of a base class to be reusable for creating instances of a new class derived from the base class. A base class intended to be replaceable later is declared to be replaceable. In the case of a compiled language, the programming code defining and using the base class is compiled into a reusable module. Later, a new class derived from the base class is identified as a replacement for the base class and is used in new programming code that uses the existing reusable module. The replacement relationship between the old base class and the new class is registered. During execution of the program, when the old code of the reusable module indicates the creation of an object of the base class, the registered replacement information is referenced. If the old class is to be replaced with the new class, the creation information for the new class is passed instead so that an object of the new class is created. The class replacement may be implemented with compiled and interpreted programming languages. When a compiled language is used, the class replacement may be implemented with new compiler-supported features that emit data for class replacement into the .obj files, but may also be implemented without requiring changes to existing compilers.

A system is presented for optimizing safe downcasting and similar programming idioms in an object-oriented programming language. The system operates by receiving a source program written in the object-oriented programming language. The system compiles this source program into an intermediate representation. Next, the system examines the intermediate representation to identify the use of a virtual function call to determine if an object of a given base class is a member of a given derived class. Such usage facilitates safe downcasting of the object from the given base class to the given derived class. If the intermediate representation uses the virtual function call in this manner, the system replaces the virtual function call with a comparison of a virtual function table pointer associated with the object to an address of a virtual function table associated with the given derived class. The compiler finishes compiling the intermediate representation into executable binary code.
