InvocationHandler
]:proxy
- The proxy instance that the method was invoked onmethod
- The Method
instance corresponding to
the interface method invoked on the proxy instance. The declaring
class of the Method
object will be the interface that
the method was declared in, which may be a superinterface of the
proxy interface that the proxy class inherits the method through.args
- An array of objects containing the values of the
arguments passed in the method invocation on the proxy instance,
or null
if interface method takes no arguments.
Arguments of primitive types are wrapped in instances of the
appropriate primitive wrapper class, such as
java.lang.Integer
or java.lang.Boolean
.null
and the interface method's return type is
primitive, then a NullPointerException
will be
thrown by the method invocation on the proxy instance. If the
value returned by this method is otherwise not compatible with
the interface method's declared return type as described above,
a ClassCastException
will be thrown by the method
invocation on the proxy instance.PersistenceBrokerException
- The exception to throw from the method
invocation on the proxy instance. The exception's type must be
assignable either to any of the exception types declared in the
throws
clause of the interface method or to the
unchecked exception types java.lang.RuntimeException
or java.lang.Error
. If a checked exception is
thrown by this method that is not assignable to any of the
exception types declared in the throws
clause of
the interface method, then an
UndeclaredThrowableException
containing the
exception that was thrown by this method will be thrown by the
method invocation on the proxy instance.UndeclaredThrowableException
