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 TCPb

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.

Overrides:

duplicate in class TCPb

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 TCPb

timeout

protected void timeout(java.lang.Object evt_)

Description copied from class: Module

The handler invoked when a timeout event occurs. Subclasses should override it to handle such an event.

Overrides:

timeout in class TCP

Following copied from class: drcl.net.Module

Module.setTimeout(Object, double), Module.setTimeoutAt(Object, double)

dataArriveAtUpPort

protected void dataArriveAtUpPort(java.lang.Object data_,
                                  Port upPort_)

Description copied from class: Module

The handler invoked when a packet arrives at an "up" port. Subclasses should override it to handle such an event.

Overrides:

dataArriveAtUpPort in class TCPb

dataArriveAtDownPort

protected void dataArriveAtDownPort(java.lang.Object data_,
                                    Port downPort_)

Description copied from class: TCPb

The down port follows the PktDelivery contract.

Overrides:

dataArriveAtDownPort in class TCPb

getLocalPort

public int getLocalPort()

Description copied from interface: drcl.inet.transport.Connection

Returns the local port.

Overrides:

getLocalPort in class TCP

getRemotePort

public int getRemotePort()

Description copied from interface: drcl.inet.transport.Connection

Returns the peer port.

Overrides:

getRemotePort in class TCP

getLocalAddr

public long getLocalAddr()

Description copied from interface: drcl.inet.transport.Connection
