Method Detail

toBytes

public byte[] toBytes()

Description copied from interface: Byteable

The recommendation that the first four bytes contain the integer packet type is for bring able to write efficient demultiplexers that will not attempt to decode an incoming packet unless the type matches one of the types they expect to receive. Not following this requirement will will not break applications but can result in wasted decoding attempts if the inital bytes happen to accidentally match the header patterns used by other demultiplexers.

Specified by:

toBytes in interface Byteable

Returns:

byte[] serialized form of this object. It is recommended that the first four bytes contain the integer packet type of this packet in network byte order, i.e., ByteBuffer.wrap(bytes,0,4).getInt() should return the expected type on the bytes being returned.
