virtual bool receivedPacket ( const DataBlock & packet )

protectedvirtual

Process a packet received by the receiver's interface This method is thread safe

Parameters

packet The received packet

Returns: True if message was successfully processed

Implements SignallingReceiver.

◆ setDebug()

void setDebug	(	bool	printFrames,
		bool	extendedDebug )

inline

Set debug data of this layer

Parameters

printFrames	Enable/disable frame printing on output
extendedDebug	Enable/disable hex data dump if print frames is enabled
