Method Detail

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

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

setDataUnit

public void setDataUnit(int dataUnit_)

The source sends a byte array of size dataUnit_ indefinitely.

Parameters:

dataUnit_ - size of the byte array; default is 512.

getDataUnit

public int getDataUnit()

setSize

public void setSize(long size_)

getSize

public long getSize()

_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

_resume

protected void _resume()

Description copied from class: Component

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

Overrides:

_resume 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

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.
