Class ExecutionContextKeeper

java.lang.Object

org.palladiosimulator.simulizar.action.interpreter.ExecutionContextKeeper

public final class ExecutionContextKeeper
extends Object

Utility class, realized as a singleton, to maintain associations between ExecutionContext s and SimuComSimProcesses. More precisely, the ExecutionContext of any AdaptationBehavior that is executed asynchronously (i.e., one of its AdaptationBehavior#executeAsync(org.palladiosimulator.simulizar.action.instance.RoleSet) methods has been called) is maintained here together with the simulation processed which executes the behavior.
