Interface ErrorRecorder

All Known Implementing Classes:

ObjectFilter, ThreadFilter, TraceFileTarget

public interface ErrorRecorder

Interface which marks an object as having error recording and reporting capabilities.

Objects which need to report error conditions to a controlling object, and to defer error handling by capturing and storing exceptions in lieu of handling them immediately, should implement this interface. It is intended primarily for use by event listeners which interact with a stateful and potentially unreliable underlying object, such as a file stream.
