Method Detail

propagate

public static java.lang.RuntimeException propagate(java.lang.Throwable t)

Convenience method to throw a RuntimeException and Error directly or wrap any other exception type into a RuntimeException.

Parameters:

t - the exception to throw directly or wrapped

Returns:

because propagate itself throws an exception or error, this is a sort of phantom return value; propagate does not actually return anything

throwIfFatal

public static void throwIfFatal(java.lang.Throwable t)

Throws a particular Throwable only if it belongs to a set of "fatal" error varieties. These varieties are as follows:

• VirtualMachineError
• ThreadDeath
• LinkageError

This can be useful if you are writing an operator that calls user-supplied code, and you want to notify subscribers of errors encountered in that code by calling their onError methods, but only if the errors are not so catastrophic that such a call would be futile, in which case you simply want to rethrow the error.

Parameters:

t - the Throwable to test and perhaps throw
