Examples of SLAPolicyHandler

org.rioproject.impl.sla.SLAPolicyHandler
A SLAPolicyHandler handles thresholds for a ThresholdWatch, registering to a ThresholdManager. If a threshold is crossed (breached or cleared), the SLAPolicyHandler will fire a SLAThresholdEvent using an EventHandler provided The SLAPolicyHandler should be extended to provide logic on how to process specific policy (if-then-else logic) on how to manage SLA Thresholds produced by ThresholdWatch instantiations @author Dennis Reedy
