Package org.palladiosimulator.probeframework.probes

Probes specify which probe type they measure (using metrics such as "current time" or "CPU state/queue size"). In particular, probes know how to measure their type, i.e., they come with a suitable implementation. Once implemented, probes can be placed all over the simulator to steadily probe. This package provides the (widely abstract) type hierarchy for such probes. Probed environments (e.g., a simulator) typically have to create concrete subclasses of appropriate probe types to realize their concrete probe variant (concrete probes depend on the implementation of the instrumented environment). The superclass of all probes is the Probe class.

Class Summary

Class	Description
BasicEventProbe<EventSourceType,V,Q extends javax.measure.quantity.Quantity>	Basic event probes refer to exactly one base metric description, thus, specializing the general event probe.
BasicObjectStateProbe<StateObjectType,V,Q extends javax.measure.quantity.Quantity>	This class realizes a basic triggered probe that observes an object's state, thus, additionally maintaining an observeredStateObject member variable.
BasicTriggeredProbe<V,Q extends javax.measure.quantity.Quantity>	Implements the doMeasure method by returning a BasicMeasurement, i.e., a measurement for a BaseMetricDescription.
EventProbe<EventSourceType>	Event probes measure as soon as an event is emitted for which they are registered.
EventProbeList	Event probe lists group a list of subsumed, triggered probes that are triggered as soon as an additional, dedicated event probe emits an event.
Probe	This class is the abstract super class for all probe implementations.
TriggeredProbe	Triggered probes measure as soon as their takeMeasurement method is invoked (with optional context parameter of type RequestContext, e.g., the thread that triggered the probe.
TriggeredProbeList	Triggered probe lists group a set of subsumed, triggered probes.
