Package org.apache.bsf.util.event

Class EventAdapterRegistry

java.lang.Object
org.apache.bsf.util.event.EventAdapterRegistry
public class EventAdapterRegistry extends Object
The EventAdapterRegistry is the registry of event adapters. If a desired adapter is not found, the adapter will be dynamically generated when lookup is attempted. Set the dynamic property to false to disable this feature.

This implementation first looks for an adapter in its lookup table and if it doesn't find one looks for a standard implementation of that adapter in the org.apache.bsf.util.event.adapters package with a standard naming convention. The naming convention it assumes is the following: for event listener type a.b.c.FooListener, it loads an adapter of type org.apache.bsf.util.event.adapters.a_b_c_FooAdapter. If both the loading and the dynamic generation fail, then a null is returned.
