public class SignedShortCodec
Encodes and decodes SLIP message headers containing the payload length. On
encoding the codec converts the signed integer value into a signed short
first ensuring that the length value will fit in a signed short.
(ie. 0--> 2^15 - 1).
In order to decode SLIP messages, the codec simply needs to read the short
value into an integer.

public int |
|
public void |
encode(ByteBuffer buffer, Integer length) |
public int decode (ByteBuffer buffer)
Decodes the length value from the specified buffer
Parameters:
buffer The ByteBuffer from which to decode the payload length
value
public void encode (ByteBuffer buffer, Integer length)
Encodes the payload length into the specified buffer by converting the
signed integer value into a signed short. This function first ensures the
integer value will fit in a signed short (0--> 2^15-1)
Parameters:
buffer The ByteBuffer into which the length header should be
encoded
length The signed integer value representing the size of the SLIP
message's associated payload (in bytes). Must fit into a signed short
(0 --> 2^15-1)
