  org.elkoserver.foundation.net.JSONByteIOFramerFactory

All Implemented Interfaces:

ByteIOFramerFactory

public class JSONByteIOFramerFactory
extends Object
implements ByteIOFramerFactory

Byte I/O framer factory for JSON messaging over a byte stream. The framing rule used is: a block of one or more non-empty lines terminated by an empty line (i.e., by two successive newlines).

On input, each block matching this framing rule is regarded as a parseable unit; that is, it is expected to contain one or more syntactically complete JSON messages. The entire block is read into an internal buffer, then parsed for JSON messages that are fed to the receiver.

On output, each message being sent is framed according to this rule.
