Abstract: Methods and apparatus, including computer program products, related to extensibility of pattern components in a visual modeling language environment. A pattern component may implement an interface, the pattern component may be received (e.g., by a compiler), and a determination may be made as to whether components of the interface are implemented by the pattern component. If so, a reference to the interface is bound to the pattern component (e.g., a function call referencing a function signature of an interface may be substituted with a call to a function having the same name of the pattern component). A role may be assigned to a pattern component of a visual modeling environment of an application development system and a behavior may be performed based on the role assigned to the pattern component.

Abstract: A computer-implemented method, system, and computer program product for enabling hot deployment of changes to an implementation of an application. An application pattern is generated. The application pattern includes one or more pattern modules, each pattern module comprising a model, a design time application component to provide content for the model, a runtime application component to execute the model with the content, and a plurality of interfaces that define dependencies between the design time component and runtime component of a first pattern module and respective design time component and runtime component of a second pattern module. The implementation of the application is bound to the plurality of interfaces, such that changes made to the application pattern are added to the implementation of the application.

Abstract: A computer-implemented method, system, and computer program product for generating an application based on a selection of one or more application patterns. A model of an operation of the application is generated. A design time application component to provide content for the model is provided, as well as a runtime application component to execute the operation associated with the model based with the content. The model, design time application component, and runtime application component are linked together to form a pattern module, the pattern module being an executable and portable operation of the application.

Abstract: A design-time architecture that allows for flexible creation of application programs is disclosed. A composer core generates displays of application components and application interfaces that define patterns of functions and interactions between interfaces. A pattern base kit tool may provide common logic for the application components. A repository stores the application components and interfaces during run-time.

Abstract: Methods and apparatus, including computer program products, for generating runtime entities in a visual modeling environment. Input characterizing an application definition at designtime is received, a determination is made as to whether the designtime entity is to be compiled by a first generator or a second generator, and a runtime version of the designtime entity is generated. The application definition can include a designtime entity and a configuration of properties of the designtime entity. The first generator can support compilation of multiple types of designtime entities and the second generator can support compilation of a specific type of designtime entity. The runtime version can be generated with the second generator if the second generator is to be used or, otherwise, generated with the first generator.

The method includes the steps of retrieving at least one software entity from a first repository in response to a first input and receiving a declaration from a user for adapting the software entity. The method further includes the steps of adapting the software entity to an adapted software entity based on the declaration and storing the adapted software entity in a second repository.

Abstract: A computer-implemented method, system, and computer program product for generating an application is disclosed. A pattern module associated with an application pattern is provided. The pattern module includes a model of the application pattern, a design time component to provide content for the model, and a runtime component to execute the operation associated with the model based with the content. A set of dependencies among the model, the design time component, and the runtime component is determined. A set of interfaces is then generated to couple the model, the design time component, and the runtime component based on the set of dependencies.

Abstract: Methods and apparatus, including computer program products, for supporting a model including descriptions of modeling language entities in a visual modeling environment. A method includes providing a visual modeling tool and modeling language entities being entities of a language of expressing applications designed in a visual modeling language environment, receiving input defining an application in the visual modeling language environment, and generating a platform-independent model of the application based on the input and the modeling language entities. In that method, the modeling language entities have a corresponding syntactic description that can be in accordance with the language, the input defines the application as a selection of the modeling language entities and a configuration of the selection, and the platform-independent model includes the selection, the configuration, and a syntactic description of the modeling language entities in the selection.

Abstract: Methods and apparatus, including computer program products, for selectively supporting extensions to a modeling language. A method includes receiving a request to extend a modeling language entity and selectively providing support to define an extension of the modeling language entity. Support is selectively provided by determining whether the support to define the extension of the modeling language entity can be provided based on a definition of the modeling language entity in a visual modeling language. If the support can be provided, the support is provided; otherwise, the support is excluded. The method can further include selectively generating the extended modeling language entity. The extended modeling language entity can be selectively generated by determining whether the extension meets one or more conditions for being a valid extension to the modeling language entity, and if the extension meets the conditions, the extended modeling language entity is generated.
