publicPacketSignalemitter

public inline Base64PacketEncoder()

public inline virtual void process(IPacket& packet)

This method performs processing on the given packet and emits the result.

Note: If packet processing is async (the packet is not in the current thread scope) then packet data must be copied. Copied data can be freed directly aFter the async call to emit() the outgoing packet.
