Class JZtxtcmdThreadQueue

java.lang.Object

org.vishia.cmd.JZtxtcmdThreadData

org.vishia.cmd.JZtxtcmdThreadQueue

All Implemented Interfaces:

java.lang.Runnable

public class JZtxtcmdThreadQueue
extends JZtxtcmdThreadData
implements java.lang.Runnable

This class builds a queue to run sub routines in an separated Thread of JZtxtcmd execution. It is similar working in CmdQueue but only for sub routines with the stable Scriptlevel as base for execution. It is similar working in JZtxtcmdThread but it has a queue and waits for execution of new sub routines.
This class is used as aggregate in org.vishia.gral.ifc.GralActionJztc to run sub routines of JZtxtcmd as action from widgets.
