Package com.atlassian.instrumentation.operations

Interface Summary

Interface	Description
ExternalOpValue	ExternalOpValue can be used to read values from "external" places in the system and provide them as OpSnapshot values.
OpInstrument	An OpInstrument is a type of @{link Instrument} that exposes 8 values.
OpTimer	OpTimer is an interface to represent the "timing" of a particular computing operation.
OpTimer.HeisenburgResultSetCalculator	This interface can be used to avoid HEISENBERG effects when trying to time how long an operation takes.
OpTimer.OnEndCallback	This interface can be provided to OpTimerFactory are creation time to have a call back when OpTimer.end(long) is called
OpTimerFactory	This will create OpTimer instances
ThreadOpTimerFactory	This factory allows you to track values for a given thread.

Class Summary

Class	Description
CachedExternalOpValue	This class allows ExternalOpValues to be computed on as as needed basis and also cache the values for a certain length of time.
ExternalOpInstrument	This class represents an OpInstrument that is calculated externally on demand from values that are "external" to this class.
OpCounter	A OpCounter can keep track of how long a computing operation takes and how many times it has been invoked, as well as optionally how bug the result set size was
OpSnapshot	This is an snapshot instance of a named operation's timing, invocation count and its result set size.
SimpleOpTimer	A new instance of this class will begin a profiling operation, one that can count how long an operation takes and how much CPU it used.
SimpleOpTimerFactory	An implementation of OpTimerFactory
ThreadLocalOpTimerFactory	ThreadOpTimerFactory that is implemented using a ThreadLocal.
