Class EventAdapterRegistry
java.lang.Object
|
+--com.ibm.bsf.util.event.EventAdapterRegistry
- public class EventAdapterRegistry
- extends java.lang.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 com.ibm.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
com.ibm.bsf.util.event.adapters.a_b_c_FooAdapter.
If both the loading and the dynamic generation fail, then a
null
is returned.

EventAdapterRegistry
public EventAdapterRegistry()
setClassLoader
public static void setClassLoader(java.lang.ClassLoader cloader)
- Class loader to use to load event adapter classes.
setDynamic
public static void setDynamic(boolean dynamic)
- Indicates whether or not to dynamically generate adapters; default is
true
.
If the dynamic
property is set to true, and the
ClassLoader
is unable to resolve an adapter, one will be
dynamically generated.
- Parameters:
dynamic
- whether or not to dynamically generate adapters.
register
public static void register(java.lang.Class listenerType,
java.lang.Class eventAdapterClass)
lookup
public static java.lang.Class lookup(java.lang.Class listenerType)
