Systems and methods for implementing aggregation containers
View Patent ↗A container object decorated with a proxy attribute is intercepted when instantiated at runtime, and a component that is an instance of a type dynamically created at runtime is returned, which implements interfaces corresponding to each of the individual interfaces of the objects extended in the container object by delegating to the extended objects. Alternately, a similar container object, when instantiated at runtime, would return a proxy object which contains a lookup table that maps interfaces to the extended objects within the component. The proxy object intercepts all calls to the container object and redirects them appropriately to the proxy objects corresponding to the extended objects, which may in turn redirect calls appropriately.
1. A method for implementing a proxy interception aggregation container, said method comprising:
decorating a container object with:
a plurality of container object attributes;
a proxy attribute, wherein the proxy attribute allows the original container object to be intercepted;
a plurality of interfaces that interface with a plurality of members to be extended by the container object, wherein the interfaces comprise container interfaces and indirect member interfaces, the indirect member interfaces not requiring use of an internal method to delegate calls to the member; and
upon an instantiation of the container object at runtime, the instantiation being intercepted by the proxy attribute, returning a proxy object that intercepts all calls to the container and redirects the calls to the a proxy object corresponding to a member that further redirects the calls, wherein the proxy object comprises:
a hash table, the hash table mapping interfaces to the members within the container.
2. The method of claim 1 wherein the method is implemented in a Component Object Model.
3. The method of claim 1 wherein the method is implemented in managed code.
4. A computer system comprising a processor means, a memory means, and a storage means including executable instructions for instructing the processor to execute the following steps:
decorate a container object with:
a plurality of container object attributes;
a proxy attribute, wherein the proxy attribute allows the original container object to be intercepted;
a plurality of interfaces that interface with a plurality of members to be extended by the container object, wherein the interfaces comprise container interfaces and indirect member interfaces, the indirect member interfaces not requiring use of an internal method to delegate calls to the member; and
instantiate the container object at runtime, the instantiation being intercepted by the proxy attribute, returning a proxy object that intercepts all calls to the container and redirects the calls to the a proxy object corresponding to a member that further redirects the calls, wherein the proxy object comprises:
a hash table, the hash table mapping interfaces to the members within the container.
