Abstract

An extensible framework for object oriented programming comprises a reception component that receives a customized strategy relating to composing a target object. An implementation component automatically implements the customized strategy to compose the target object based at least in part upon context associated with the target object. The extensible framework can further comprise a context component that determines the context, including context of an application associated with the target object, existing objects associated with the target object, and relationships between the existing objects.

Claims

1. An extensible framework for object oriented programming comprising the following computer-executable components:

a reception component that receives a customized strategy relating to composing a target object; and

an implementation component that automatically implements the customized strategy to compose the target object based at least in part upon a context associated with the target object.

2. The framework of claim 1, the strategy is implemented at runtime.

3. The framework of claim 1, further comprising a context component that determines the context, including context of an application associated with the target object, existing objects associated with the target object, and relationships between the existing objects, wherein the context is a set of components that are relevant to the application and the target object and at least one of the existing objects is a remote object.

4. The framework of claim 1, the reception component receives a plurality of strategies.

5. The framework of claim 4, further comprising an ordering component that facilitates execution of the plurality of strategies in an order that is determined by at least one of a declarative statement and context associated with the target object.

6. The framework of claim 1, the implementation component creates a new object based at least in part upon the customized strategy.

7. The framework of claim 1, the target object is an object that is to be created by the implementation component.

8. The framework of claim 1, the target object is a pre-existent object.

9. The framework of claim 1, further comprising a policy component that enforces one of a permanent policy and a transient policy with respect to the strategy.

10. The framework of claim 1 configured to employ inferences in connection with composing the target object.

11. The framework of claim 10, the inferences generated based at least in part upon one or more of analyzed metadata and explicit commands.

12. The framework of claim 10, further comprising an external configuration file that is employed in connection with generating the inferences.

13. A method for composing an object comprising the following computer-executable acts:

receiving a plurality of composition strategies;

receiving a command to compose a target object;

analyzing context associated with the target object; and

executing at least one of the plurality of composition strategies based at least in part upon the analyzed context.

14. The method of claim 13, further comprising executing at least two of the composition strategies in a parallel manner.

15. The method of claim 13, further comprising executing at least two of the composition strategies sequentially in a specified order.

16. The method of claim 13, further comprising performing one or more of constructor dependency injection and setter injection upon executing the at least one strategy.

17. The method of claim 13, further comprising performing one or more of registering the target object and storing the target object in a container and retrieving the target object from a container upon executing the at least one strategy.

18. The method of claim 13, further comprising performing at least one of type mapping with respect to the target object upon executing the at least one strategy and providing a proxy object to the target object upon executing the at least one strategy.

19. The method of claim 13, further comprising performing attribute reflection upon executing the at least one strategy.

20. An extensible framework in an object-oriented programming environment, comprising:

computer-implemented means for receiving a composition strategy;

computer-implemented means for analyzing a context associated with a target object; and

computer-implemented means for composing the target object based at least in part upon the received composition strategy and the analyzed context.
