Class UndeclaredThrowableException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

java.lang.reflect.UndeclaredThrowableException

All Implemented Interfaces:

Serializable

public class UndeclaredThrowableException
extends RuntimeException

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.

Since:

1.3

final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

UndeclaredThrowableException

public UndeclaredThrowableException(Throwable undeclaredThrowable)

Constructs an UndeclaredThrowableException with the specified Throwable.

Parameters:

undeclaredThrowable - the undeclared checked exception that was thrown, may be null

UndeclaredThrowableException

public UndeclaredThrowableException(Throwable undeclaredThrowable,
 String s)

Constructs an UndeclaredThrowableException with the specified Throwable and a detail message.

Parameters:

undeclaredThrowable - the undeclared checked exception that was thrown, may be null

s - the detail message, may be null

Method Details

getUndeclaredThrowable

public Throwable getUndeclaredThrowable()

Returns the Throwable instance wrapped in this UndeclaredThrowableException, which may be null.

API Note:

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
