Nested Class Summary

static class

JBinding.DefaultJBinding An abstract adaptor that provides a default implementation for a binding.

Field Summary

static int

NULL_ID A status code that indicates that no protocol was matched

Method Summary

int	getSourceId() Protocol header ID for this binding.
int	getTargetId() Protocol header ID to which this binding is bound to.
boolean	isBound(JPacket packet, int offset) Checks the length of the header that has not been bound yet.
int[]	listDependencies() A list of dependencies that a binding has.

Field Detail

NULL_ID

static final int NULL_ID

A status code that indicates that no protocol was matched

Method Detail

getTargetId

int getTargetId()

Protocol header ID to which this binding is bound to.

Returns:

numerical protocol ID as assigned by JRegistry

isBound

boolean isBound(JPacket packet,
                int offset)

Checks the length of the header that has not been bound yet. The returned length value provides 2 pieces of information. 1st, length of 0 indicates that the header is not bound. 2nd, length of non zero indicates that the header is bound and either the entire or trucated length of the header.

Parameters:

packet - packet and its data buffer

offset - offset into the packet data buffer where the end of the previous header is

Returns:

either full or truncated length of the header or 0 if header is not bound at all

listDependencies

int[] listDependencies()

A list of dependencies that a binding has.

Returns:

list of depdencies

getSourceId

int getSourceId()

Protocol header ID for this binding.

Returns:

numerical ID of the header as assigned by JRegistry
