All Implemented Interfaces:
ExternalProcess, ExternalProcessDecorator, java.io.Serializable, UniversalProcess

public class RLoginProcess
extends AbstractExternalProcessDecorator

The RloginProcess class is able to start any class, of the ProActive library, using rlogin command.

For instance:

 ...............
 PrunSubProcess lsf = new PrunSubProcess(new SimpleExternalProcess("ls -lsa"));
 RLoginProcess p = new RLoginProcess(lsf, false);
 p.setHostname("cluster_front_end_name");
 p.startProcess();
 ...............

Constructor Detail

RLoginProcess

public RLoginProcess()
Creates a new RloginProcess Used with XML Descriptors


RLoginProcess

public RLoginProcess(ExternalProcess targetProcess)
Creates a new RloginProcess

Parameters:
targetProcess - The target process associated to this process. The target process represents the process that will be launched after logging remote host with rlogin

RLoginProcess

public RLoginProcess(ExternalProcess targetProcess,
                     boolean exitAfterCommand)
Creates a new RloginProcess

Parameters:
targetProcess - The target process associated to this process. The target process represents the process that will be launched after logging remote host with rlogin
exitAfterCommand - If true the process will finished once rlogin command is performed. The default value is false
Method Detail

getProcessId

public java.lang.String getProcessId()
Description copied from interface: UniversalProcess
Returns the id of the process

Returns:

Returns:
the number of nodes targeted. Represents the number of nodes expected to use when starting this process
See Also:
UniversalProcess.getNodeNumber()

getFinalProcess

public UniversalProcess getFinalProcess()
Description copied from interface: UniversalProcess
Returns the last process of the chain

Returns:
the last process of the chain
See Also:
UniversalProcess.getFinalProcess()

setExitAfterCommand

public void setExitAfterCommand(boolean b)
Method setExitAfterCommand

Parameters:
b - If true the process will finished once rlogin command is performed. The default vaule is false

getExitAfterCommand

public boolean getExitAfterCommand()
Returns the value of the boolean telling that the process will finished after rlogin command or will wait for another command to be pushed once logging on the remote host

Returns:
boolean

main
