Class ConsumptionEventAdapter

java.lang.Object
  hu.mta.sztaki.lpds.cloud.simulator.iaas.resourcemodel.ConsumptionEventAdapter

All Implemented Interfaces:

ResourceConsumption.ConsumptionEvent

Direct Known Subclasses:

PhysicalMachine.PowerStateDelayer, VirtualMachine.InitialTransferEvent

public class ConsumptionEventAdapter
extends Object
implements ResourceConsumption.ConsumptionEvent

This class simplifies the implementation of consumption events and provides basic functions to determine if a resource consumption has already been completed (either with a failure or success). The simplification allows the following: Instead of implementing the complete consumption event interface, one can only concentrate on actions to do on success/failure only.

Field Detail

cancelled

private boolean cancelled

shows if the resource consumption has failed to complete for some reason

completed

private boolean completed

shows if the resource consumption has successfully completed

Constructor Detail

ConsumptionEventAdapter

public ConsumptionEventAdapter()

Method Detail

conComplete

public void conComplete()

This function simply marks the success of the consumption in the completed field of the class. If this function is overridden please make sure super.conComplete() is called (this allows the other functions of this class to still operate correctly).

Specified by:

conComplete in interface ResourceConsumption.ConsumptionEvent

conCancelled

public void conCancelled(ResourceConsumption problematic)

This function simply marks the failure of the consumption in the cancelled field of the class. If this function is overridden please make sure super.conCancelled() is called (this allows the other functions of this class to still operate correctly).

Specified by:

conCancelled in interface ResourceConsumption.ConsumptionEvent

isCancelled

public boolean isCancelled()

Determines whether there was a failure in the resource consumption this event adapter is/was observing

Returns:

true if the consumption has failed

isCompleted

public boolean isCompleted()

Determines if successful completion was marked for the resource consumption this event adapter is/was observing

Returns:

true if the consumption has successfully terminated
