Method Detail

decode

public MICPMessage decode(byte[] buf,
                          int len,
                          MICPMessage into)
                   throws MICPProtocolException

Parse the given buffer as an mICP message.

Parameters:

buf - The wire data to parse.

len - The length of above buffer.

into - Message structure to fill in.

Returns:

The filled in message.

Throws:

MICPProtocolException - If the given buffer is not an mICP wire formatted message.

encode

public int encode(int op,
                  int src,
                  int id,
                  java.lang.String url,
                  byte[] buf)

Emit an MICP message into provided buffer. If the buffer is too small, a new buffer is allocated in place of the provided one (and returned).

Parameters:

op - The opcode for the message.

src - The source field for the message.

id - The identifier of that message.

url - The URL for that message.

buf - The buffer to encode the message to.

Returns:

A positive integer, giving the message length if buffer was big enough to hold the packet, a negative integer, giving required buffer size otherwise.
