Package com.voytechs.jnetstream.codec.event Description

Defines API for dipatching and handling of events generated by the Decoder during the decoding process.
A user implementing the DecoderListener interface can register itself with the decoder to be notified of specific or all types of events. The following events are supported.

• DecoderPacketEvent - A new Packet has been created
• DecoderHeaderEvent - A new Header has been created
• DecoderFieldEvent - A new Field has been created
• DecoderIncompatibleHeaderEvent - A Header was evaluated and found to be incompatible
• DecoderSnaplenEvent - Processing of packet was terminated due to Snaplen limitation.
• DecoderSyntaxEvent - A syntax error or warning event
• DecoderExpressionEvent - A numerical or string expression error occured

Event is dispatched to the listeners who implement the DecoderListener interface using the processDecoderEvent() method. You also can throw AssertFailure exception which will cause the decoder to abort what it was doing. I.e. if you hare handling a DecoderPacketEvent and throw the AssertFailure exception, the decoder will abort the packet and not return it to the user.
