Class RecordingExceptionHandler

java.lang.Object

net.openhft.chronicle.core.onoes.RecordingExceptionHandler

All Implemented Interfaces:

ExceptionHandler

public class RecordingExceptionHandler
extends Object
implements ExceptionHandler

RecordingExceptionHandler is a concrete implementation of the ExceptionHandler interface. It records each exception by incrementing a count in a provided map, using an ExceptionKey as the key.

Each ExceptionKey is constructed using a LogLevel, the Class where the exception happened, a custom message, and the Throwable object representing the exception. The LogLevel is provided at instantiation, while the rest are provided when an exception occurs.

If the exceptionsOnly flag is set, the handler will ignore errors that are not associated with a Throwable.
