Class ScriptComponent

java.lang.Object
  org.rhq.modules.plugins.script2.ScriptComponent

All Implemented Interfaces:

AvailabilityFacet, ResourceComponent, MeasurementFacet, OperationFacet

public class ScriptComponent
extends Object
implements ResourceComponent, MeasurementFacet, OperationFacet

Run the show for the script2 plugin. We eval() the script for each call to getAvailability and getValues , as otherwise we may see failures, when evaluated script was evaluated on a different thread than the execution of invokeFunction.
