public class DefaultAdaptiveTimeoutHandler
extends DefaultVisualTimeoutHandler
implements AdaptiveTimeoutHandler

Timeout handler that individually adapts itself to the user by reducing and increasing the timeout duration. The interval of adaptation is given by the minDuration and maxDuration values. A level change resets the timeout duration.

Method Detail

processExecutionPhase

public void processExecutionPhase(ExecutionContext context)

Description copied from interface: ExecutionPhaseListener

Called by the Executor to signal an element execution context

Specified by:

processExecutionPhase in interface ExecutionPhaseListener

Overrides:

processExecutionPhase in class DefaultVisualTimeoutHandler

adaptTimeoutDuration

public void adaptTimeoutDuration(ExecutionContext event)
