AbstractBinding

public AbstractBinding(java.lang.Class<? extends JHeader> sourceClass,
                       java.lang.Class<H> targetClass)

Method Detail

getSourceId

public int getSourceId()

Description copied from interface: JBinding

Protocol header ID for this binding.

Specified by:

getSourceId in interface JBinding

Returns:

numerical ID of the header as assigned by JRegistry

getTargetId

public int getTargetId()

Description copied from interface: JBinding

Protocol header ID to which this binding is bound to.

Specified by:

getTargetId in interface JBinding

Returns:

numerical protocol ID as assigned by JRegistry

isBound

public boolean isBound(JPacket packet,
                       int offset)

Description copied from interface: JBinding

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.

Specified by:

isBound in interface JBinding

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

isBound

public abstract boolean isBound(JPacket packet,
                                H header)

listDependencies

public int[] listDependencies()

Description copied from interface: JBinding

A list of dependencies that a binding has.

Specified by:

listDependencies in interface JBinding

Returns:

list of depdencies
