Method Details

rethrow

public KVException rethrow()

Rethrow this exception, which may have been created in a different thread, in the context of the current thread.

This method ensures the current thread's stack frames are included in the thrown exception.

This method never returns, but has a return type that can be "thrown" to facilitate source code control flow.

Returns:

never

Throws:

KVException - always, as a duplicate of this exception with the current thread's stack frame context

duplicate

public KVException duplicate()

Create a duplicate of this exception, with the current thread's stack frames prepended.

This allows the "same" exception to be thrown multiple times from different locations with different outer stack frames. The clone() method is used to copy this instance.

Returns:

duplicate of this exception with the current thread's stack frame context
