Constructor Detail

Ping

public Ping()

Constructs a new Ping instance.

Method Detail

appSetConfigData

public void appSetConfigData(java.lang.String cdata)

Sets application-specific configuration data.

Specified by:

appSetConfigData in class LogicalProcess

Parameters:

cdata - String representing configuration data.

appToString

public java.lang.String appToString()

Implements abstract method for dispaly purpose only

Specified by:

appToString in class LogicalProcess

appSavingLPState

public LogicalProcess appSavingLPState()

Implements abstract method to save LP state

Specified by:

appSavingLPState in class LogicalProcess

appSetLPState

public void appSetLPState(LogicalProcess lp)

Implements abstract method to set the state of this LP to the state of a specified Ping

Specified by:

appSetLPState in class LogicalProcess

Parameters:

lp - LogicalProcess containing the state information; the application program decides what state information need to be stored

appInitializeLP

public boolean appInitializeLP()

Initiates the LP and generates the initial message. It's the counterpart of "IProc" in GTW.

Specified by:

appInitializeLP in class LogicalProcess

Returns:

false if initialization failed for some reason, true if successful.

appRunLP

public void appRunLP(java.lang.Object content,
                     java.lang.String sender)

Handles events for Ping. It is the counterpart of "Proc" in GTW.

Specified by:

appRunLP in class LogicalProcess

Parameters:

content - an Object representing the content of the message to be sent

sender - String the application-assigned name of the sender of this message

appFinalizeLP

public void appFinalizeLP()

Terminates LP and displays simulation statistics. It is optionally called at the end of the simulation. It is the counterpart of "FProc" in GTW.

Specified by:

appFinalizeLP in class LogicalProcess

appGetState

public java.lang.String appGetState(java.lang.String name)

Method to get the value of a given application-level monitorable variable.

Specified by:

appGetState in class LogicalProcess

Parameters:

name - The name of the variable to monitor

Returns:

The value of the variable in question

Since:

1.5

appSetState

public java.lang.String appSetState(java.lang.String name,
                                    java.lang.String val)

Method to set the value of a given application-level monitorable variable.

Specified by:

appSetState in class LogicalProcess

Parameters:

name - The name of the variable to steer

val - The value to assign to the variable

Returns:

Null if the steering was successful, else a String describing the error that occurred.

Since:

1.5

appGetSteerable

public java.util.List<java.lang.String> appGetSteerable()

Returns a List of Strings describing all application-specific steerable parameters of this LP, each in the form "paramName, paramType".

Specified by:

appGetSteerable in class LogicalProcess

Returns:

List listing all application-specific steerable parameters.

Since:

1.5

appGetMonitorable

Returns a List of Strings describing all application-specific monitorable parameters of this LP, each in the form "paramName, paramType".

Specified by:

appGetMonitorable in class LogicalProcess

Returns:

List listing all application-specific montiorable parameters.

Since:

1.5
