Class IfController

java.lang.Object
  extended by org.apache.jmeter.testelement.AbstractTestElement
      extended by org.apache.jmeter.control.GenericController
          extended by org.apache.jmeter.control.IfController
All Implemented Interfaces:
Serializable, Cloneable, Controller, Searchable, TestElement, TestCompilerHelper

public class IfController
extends GenericController
implements Serializable

This is a Conditional Controller; it will execute the set of statements (samplers/controllers, etc) while the 'condition' is true.

In a programming world - this is equivalant of :

 if (condition) {
          statements ....
          }
 
In JMeter you may have :
 
 Thread-Group (set to loop a number of times or indefinitely,
    ... Samplers ... (e.g. Counter )
    ... Other Controllers ....
    ... IfController ( condition set to something like - ${counter}<10)
       ... statements to perform if condition is true
       ...
    ... Other Controllers /Samplers }

constructor

Method Detail

setCondition

public void setCondition(String condition)
Condition Accessor - this is gonna be like ${count}<10


getCondition

public String getCondition()
Condition Accessor - this is gonna be like ${count}<10


isDone

public boolean isDone()
This is overriding the parent method. IsDone indicates whether the termination condition is reached. I.e. if the condition evaluates to False - then isDone() returns TRUE

Specified by:
isDone in interface Controller
Overrides:
isDone in class GenericController
Returns:
boolean
See Also:
Controller.isDone()

next

public Sampler next()
Description copied from class: GenericController

Determines the next sampler to be processed.

If isDone, 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
See Also:
Controller.next()

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

isEvaluateAll

public boolean isEvaluateAll()

setEvaluateAll

public void setEvaluateAll(boolean b)

isUseExpression

public boolean isUseExpression()

setUseExpression

public void setUseExpression(boolean selected)
