Class UndeclaredThrowableException
- All Implemented Interfaces:
Serializable
UndeclaredThrowableException
Thrown by a method invocation on a proxy instance if its invocation handler's
invoke
method throws a checked exception (a Throwable
that is not assignable to RuntimeException
or Error
) that is not assignable to
any of the exception types declared in the throws
clause of the method that was invoked
on the proxy instance and dispatched to the invocation handler.
An UndeclaredThrowableException
instance contains the undeclared checked exception that
was thrown by the invocation handler, and it can be retrieved with the
getUndeclaredThrowable()
method. UndeclaredThrowableException
extends
RuntimeException
, so it is an unchecked exception that wraps a checked exception.
As of release 1.4, this exception has been retrofitted to conform to the general purpose
exception-chaining mechanism. The "undeclared checked exception that was thrown by the invocation
handler" that may be provided at construction time and accessed via the
getUndeclaredThrowable()
method is now known as the cause, and may be accessed
via the Throwable.getCause()
method, as well as the aforementioned "legacy method."
