All Implemented Interfaces:

ContextAware, LifeCycle

public class NopThrowableInformationConverter
extends ThrowableHandlingConverter

Always returns an empty string.

This converter is useful to pretend that the converter chain for PatternLayout actually handles exceptions, when in fact it does not. By adding %nopex to the conversion pattern, the user can bypass the automatic addition of %ex conversion pattern for patterns which do not contain a converter handling exceptions.

Users can ignore the existence of this converter, unless they want to suppress the automatic printing of exceptions by PatternLayout.
