All Implemented Interfaces:

public class ParamModifier
extends AbstractTestElement
implements TestListener, PreProcessor, Serializable

This modifier will replace any single http sampler's url parameter value with a value from a given range - thereby "masking" the value set in the http sampler. The parameter names must match exactly, and the parameter value must be preset to "*" to diferentiate between duplicate parameter names.

For example, if you set up the modifier with a lower bound of 1, an upper bound of 10, and an increment of 2, and run the loop 12 times, the parameter will have the following values (one per loop): 1, 3, 5, 7, 9, 1, 3, 5, 7, 9, 1, 3

The ParamMask object contains most of the logic for stepping through this loop. You can make large modifications to this modifier's behaviour by changing one or two method implementations there.
