Member Function Documentation

packetize()

bool packetize ( const Buffer &  buf, std::uint16_t  bufferSize, std::int32_t &  offset, std::uint16_t &  length  )

overridevirtual

Parameters

buf	reference to the buffer in which the packet should be found
bufferSize	the actual size of the buffer
offset	[out] if a packet was found the start offset of it
length	[out] if a packet was found the length of the packet(overall)

Returns

true if packet was found false otherwise

Implements PacketizerBase.
