Abstract base class for ExtensionHandler implementations that do not have to maintain their own state. Concrete implementations can choose with of the default implementations of handleExtendedInterfaceCall(IBeanContext, IBeanFieldAccess, Object, Method, Object[]), ExtensionHandler.interceptGetterCall(IBeanContext, IBeanFieldMetaInfo, Object, Object) and ExtensionHandler.interceptSetterCall(IBeanContext, IBeanFieldMetaInfo, Object, Object) to override.

handleExtendedInterfaceCall

public Object handleExtendedInterfaceCall(IBeanContext<?> context,
                                          IBeanFieldAccess bean,
                                          Object proxyInstance,
                                          Method method,
                                          Object[] params)
                                   throws Throwable

This default implementation always throws a UnsupportedOperationException. Should be always overridden in case the extension interface contains its own methods.

Specified by:

handleExtendedInterfaceCall in interface ExtensionHandler

Parameters:

context - provides meta information about the bean

bean - allows this method to read or change field values of the IBean

proxyInstance - the IBean instance object (see InvocationHandler.invoke(Object, Method, Object[]) for more details)

method - the Method of the extension interface that was called on the IBean (see InvocationHandler.invoke(Object, Method, Object[]) for more details)

params - the parameters passed to the extension method call (see InvocationHandler.invoke(Object, Method, Object[]) for more details)

Returns:

an object that matches to the return type of the extension method; return null if the return type is void. (see InvocationHandler.invoke(Object, Method, Object[]) for more details)

Throws:

Throwable - can be any Error, RuntimeException or checked exception that is definied in the signature of the extension method. (see InvocationHandler.invoke(Object, Method, Object[]) for more details)
