All Implemented Interfaces:

Bundler

Direct Known Subclasses:

AsyncNoBundler, BatchBundler

public class NoBundler
extends java.lang.Object
implements Bundler

Bundler which doesn't bundle :-) Can be used to measure the diff between bundling and non-bundling (e.g. at runtime) This bundler doesn't use a pool of buffers, but creates a new buffer every time a message is sent.

Since:

4.0

NoBundler

public NoBundler()

Method Detail

size

public int size()

Description copied from interface: Bundler

The number of unsent messages in the bundler

Specified by:

size in interface Bundler

getMaxSize

public int getMaxSize()

Description copied from interface: Bundler

Maximum number of bytes for messages to be queued until they are sent

Specified by:

getMaxSize in interface Bundler

init

public void init(TP transport)

Description copied from interface: Bundler

Called after creation of the bundler

Specified by:

init in interface Bundler

Parameters:

transport - the transport, for further reference

getQueueSize

public int getQueueSize()

Description copied from interface: Bundler

If the bundler has a queue and it should be managed by a queuing discipline (like Random Early Detection), then return the number of elements in the queue, else -1. In the latter case, the queue won't be managed.
This method needs to be fast as it might get called on every message to be sent.

Specified by:

getQueueSize in interface Bundler

start

public void start()

Description copied from interface: Bundler

Called after Bundler.init(TP)

Specified by:

start in interface Bundler

stop

public void stop()

Specified by:

stop in interface Bundler

send

public void send(Message msg)
          throws java.lang.Exception

Specified by:

send in interface Bundler

Throws:

java.lang.Exception

sendSingleMessage

protected void sendSingleMessage(Message msg,
                                 ByteArrayDataOutputStream output)
                          throws java.lang.Exception

Throws:
