public interface ParameterHandler
extends Serializable

ParameterHandler is implemented by classes capable of handling external parameters.

What parameters are provided depend on what the Terminal provides and if the application is deployed as a servlet or portlet. URL GET parameters are typically provided to the handleParameters(Map) method.

A ParameterHandler must be registered to a Window using Window.addParameterHandler(ParameterHandler) to be called when parameters are available.
