Constructor Detail

LoopController

public LoopController()

Method Detail

setLoops

public void setLoops(int loops)

setLoops

public void setLoops(java.lang.String loopValue)

getLoops

public int getLoops()

getLoopString

public java.lang.String getLoopString()

setContinueForever

public void setContinueForever(boolean forever)

Determines whether the loop will return any samples if it is rerun.

Parameters:

forever - true if the loop must be reset after ending a run

next

public Sampler next()

Determines the next sampler to be processed.

If GenericController.isDone() is true, returns null.

Gets the list element using current pointer. If this is null, calls GenericController.nextIsNull().

If the list element is a Sampler, calls GenericController.nextIsASampler(Sampler), otherwise calls GenericController.nextIsAController(Controller)

If any of the called methods throws NextIsNullException, returns null, otherwise the value obtained above is returned.

Specified by:

next in interface Controller

Overrides:

next in class GenericController

Returns:

the next sampler or null

setDone

protected void setDone(boolean done)

Overrides:

setDone in class GenericController

nextIsNull

protected Sampler nextIsNull()
                      throws NextIsNullException

Called by GenericController.next() when GenericController.getCurrentElement() returns null. Reinitialises the controller.

Overrides:

nextIsNull in class GenericController

Returns:

null (always, for this class)

Throws:

NextIsNullException - when the end of the list has already been reached

triggerEndOfLoop

public void triggerEndOfLoop()

Trigger end of loop condition on controller (used by Start Next Loop feature)

Specified by:

triggerEndOfLoop in interface Controller

Overrides:

triggerEndOfLoop in class GenericController

incrementLoopCount

protected void incrementLoopCount()

resetLoopCount

protected void resetLoopCount()

getIterCount

protected int getIterCount()

Overrides:

getIterCount in class GenericController

reInitialize

protected void reInitialize()

Resets the controller (called after execution of last child of controller):

• resetCurrent() (i.e. current=0)
• increment iteration count
• sets first=true
• recoverRunningVersion() to set the controller back to the initial state

Overrides:

reInitialize in class GenericController

startNextLoop

public void startNextLoop()

Start next iteration

Specified by:

startNextLoop in interface IteratingController

breakLoop

public void breakLoop()

Description copied from interface: IteratingController

Break loop ("break" keyword equivalent)

Specified by:

breakLoop in interface IteratingController

iterationStart

public void iterationStart(LoopIterationEvent iterEvent)

Description copied from interface: LoopIterationListener

Called when a loop iteration is about to start.

Specified by:

iterationStart in interface LoopIterationListener

Parameters:

iterEvent - the event
