Description copied from interface: DataPacketHandler

Handle a Data Frame from the network.

Specified by:

onDataPacket in interface DataPacketHandler

Parameters:

channelEndpoint - from which the data is delivered.

header - of the first Data Frame in the packet (may be re-wrapped if needed)

buffer - holding the data (always starts at 0 offset)

length - of the packet (may be longer than the header frame length)

srcAddress - of the packet

Returns:

the number of bytes received.

Description copied from interface: SetupMessageHandler

Handle a Setup Frame

Specified by:

onSetupMessage in interface SetupMessageHandler

Parameters:

channelEndpoint - from which the message is delivered.

header - of the Setup Frame in the message (may be re-wrapped if needed)

buffer - holding the Setup Info (always starts at 0 offset)
