    摘要: A situation object instantiator (SOI) receives a request from a client including a typekey. Available situations are retrieved. For a retrieved situation, a call to an evaluator is made. If the situation is active a check is made to see if an instantiator exists for the typekey and situation. If so, the object instantiator is called, it returns an instance to the SOI, and the SOI returns the instance to the client. If not, more situations are retrieved until the situations are exhausted, and such is communicated to the client.

    摘要: A method, an apparatus, and computer instructions are provided for implementing dynamic function groups in a data processing system. An extensible framework is provided, which provides function groups to amalgamate extended sets of functionality by either vendor or purpose and allows the function groups to be dynamically enabled or disabled within a software application. A user may specify which extended sets of functionality are relevant and when to enable them. With the use of function groups, third party vendors may integrate added functionalities with existing ones in a software application, and indicate when these functionalities should be available to end-users without the need to duplicate code. The invention allows for the construction of other extensible frameworks including wizards, editors, and operations may also be extended with the use of function groups.
