Class ByteStreamNetPeer

java.lang.Object
  drcl.DrclObj
      drcl.comp.Component
          drcl.comp.lib.bytestream.ByteStreamNetPeer

All Implemented Interfaces:

ActiveComponent, ByteStreamConstants, java.lang.Cloneable, ObjectDuplicable, java.io.Serializable

public class ByteStreamNetPeer

extends Component

implements ByteStreamConstants, ActiveComponent

An intermediate component that acts as between a ByteStreamContract component and a real network socket.

As a reactor, it absorts any size of incoming data from the initiator and sends the data to the real socket. It always reports available buffer size of 1 to keep the initiator sending data.

As an initiator, it relays data from the real socket to the reactor in bulks of size dataUnit.

ByteStreamNetPeer

public ByteStreamNetPeer()

ByteStreamNetPeer

public ByteStreamNetPeer(java.lang.String id_)

Method Detail

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component

Duplicates the content of source_, including ID, name, child components and connections among them, to this component. Subclasses need to override this method to copy its own variables.

Specified by:

duplicate in interface ObjectDuplicable

Overrides:

duplicate in class Component

info

public java.lang.String info()

Description copied from class: Component

Returns information regarding this component. Subclasses should override this method to provide useful information at run time.

Overrides:

info in class Component

reset

public void reset()

Description copied from class: Component

Resets the component for being used anew. All the internal variables must be set to the initial state. All the ports and child components are reset as well.

Overrides:

reset in class Component

accept

public void accept(int serverPort_)

Sets up a real socket and makes the component listens to the socket.

connect

public void connect(java.lang.String serverAddress_,
                    int serverPort_)

Sets up a real socket and makes the component connects to the real remote socket.

setDataUnit

public void setDataUnit(int dataUnit_)

getDataUnit

public int getDataUnit()

_start

protected void _start()

Description copied from class: Component

This method is invoked in a new thread context when Component.run() is called. An ActiveComponent subclass must override this method to start this component.

Overrides:

_start in class Component

process

protected void process(java.lang.Object data_,
                       Port inPort_)

Description copied from class: Component

The main callback method of a component. Being invoked when data arrives at a port of its.

Overrides:

process in class Component

Parameters:

data_ - the arrival data.

inPort_ - the port where the data arrives.
