◆ GetHeadersAccepted()

std::vector< uint32_t > GetHeadersAccepted ( )
overridevirtual
Returns
lists the headers of the packets that this handler accepts only these packets will get sent to this handler. If this function returns an empty list then ALL packets will be sent to the PacketHandler i.e. a universal handler.

Implements ILocalPacketHandler.
