Uses of Interface
org.rioproject.watch.ThresholdListener

Packages that use ThresholdListener

org.rioproject.sla	Provides classes that allow policy handlers to react to SLA threshold conditions
org.rioproject.system	Provides classes that interact with lower level operating system and infrastructure elements, providing an abstract notion of a compute resource with qualitative and quantitative capabilities.
org.rioproject.watch	Provides mechanisms to collect and analyze programmer defined metrics defined in a distributed application.

Uses of ThresholdListener in org.rioproject.sla

Classes in org.rioproject.sla that implement ThresholdListener

class	RedeployPolicyHandler The RedeployPolicyHandler will redeploy a service based on declared thresholds.
class	RelocationPolicyHandler The RelocationPolicyHandler will inform the OperationalStringManager to relocate the ServiceBean that uses this policy handler.
class	ScalingPolicyHandler The ScalingPolicyHandler will increment and optionally decrement instances of the ServiceBean it is associated to based on limits set for the SLA.
class	SLAPolicyHandler A SLAPolicyHandler handles thresholds for a ThresholdWatch, registering to a ThresholdManager.

Uses of ThresholdListener in org.rioproject.system

Methods in org.rioproject.system with parameters of type ThresholdListener

void	ComputeResource.addThresholdListener(ThresholdListener listener) A helper method which will add a ThresholdListener to all contained MeasurableCapability components.
void	ComputeResource.removeThresholdListener(ThresholdListener listener) A helper method which will remove a ThresholdListener from all contained MeasurableCapability components.

Uses of ThresholdListener in org.rioproject.watch

Fields in org.rioproject.watch with type parameters of type ThresholdListener
