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."

getUndeclaredThrowable
Returns theThrowableinstance wrapped in thisUndeclaredThrowableException, which may benull.This method predates the general-purpose exception chaining facility. The
Throwable.getCause()method is now the preferred means of obtaining this information.- Returns:
- the undeclared checked exception that was thrown
-
getCause
Returns the cause of this exception (theThrowableinstance wrapped in thisUndeclaredThrowableException, which may benull). -
