scriptella.driver.script .ParametersCallbackMap

All known Subclasses:   scriptella.driver.script .BindingsParametersCallback,  scriptella.driver.jexl .JexlContextMap,
ParametersCallbackMap
public class ParametersCallbackMap implements ParametersCallback,Map<String, Object>(Code)
java.util.Map implementation of ParametersCallback for integration into Scriptella execution environment.
This class allows local variables to be set via ParametersCallbackMap.put(String,Object) method.
ParametersCallbackMap.getParameter(String) allows reading variables.
In query mode, a virtual variable query is available and exposes a method ParametersCallbackMap.next() to populate result set.

Note: current implementation does not distinguish if a vairable is absent or has a value of null.
