Interface IDispatcherExtension

All Known Implementing Classes:

DefaultDispatcherExtension

public interface IDispatcherExtension

It is possible to add dispatcher extensions so that the process of finding beans for a name can be extended by adding a dispatcher extension.

This interface is likely to be upgraded in future versions - we recommend to sub-class your implementations from DefaultDispatcherExtension which provides a compatible default behavior in case of upgrading the interface.

Instances of this interface can be adder into the dispatcher management by using DefaultDispatcher.addDispatcherExtension(IDispatcherExtension).
