SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Monitors decoder activity. This class borrowed some from the
org.xml.sax.ErrorHandler
interface and its documentation. A monitor
is a generalized callback for any sort of activity used for tracking both
successes and failures. So you'll realize similarities between monitors
and callbacks especially where the callbackOccurred() method is concerned.
Method Summary | |
void |
callbackOccured(StatefulDecoder decoder,
DecoderCallback cb,
java.lang.Object decoded)
Monitors callbacks that deliver a fully decoded object. |
void |
callbackSet(StatefulDecoder decoder,
DecoderCallback oldcb,
DecoderCallback newcb)
Monitors changes to the callback. |
void |
error(StatefulDecoder decoder,
java.lang.Exception exception)
Receive notification of a recoverable error. |
void |
fatalError(StatefulDecoder decoder,
java.lang.Exception exception)
Receive notification of a non-recoverable error. |
void |
warning(StatefulDecoder decoder,
java.lang.Exception exception)
Receive notification of a warning. |
