Method Detail

getComputationTime

public long getComputationTime()

Description copied from interface: Stats

The computation time will ideally correspond to the CPU Time or, if the JVM does not support it, the wallclock time. In comparison with the processing time, this time does not include the network and other overheads. Note that if the measured code executed a fork, the child's cpu time will not be reflected.

Specified by:

getComputationTime in interface Stats

Returns:

Returns the computation time spent by this task.

addComputationTime

public void addComputationTime(long time)

exitReadyState

public void exitReadyState()

exitProcessingState

public void exitProcessingState()

exitWaitingState

public void exitWaitingState()

exitResultsState

public void exitResultsState()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

markFinishTime

public void markFinishTime()

getWorkout

public Workout getWorkout()

addChildStats

public void addChildStats(StatsImpl stats)

getWallClockTime

public long getWallClockTime()

Specified by:

getWallClockTime in interface Stats

Returns:

Returns the time elapsed since the creation of the task until this task is finished.

getProcessingTime

public long getProcessingTime()

Description copied from interface: Stats

The processing time represents the time this node was asigned to some resource for computation. This time includes the time the node took to travel through the network.

Specified by:

getProcessingTime in interface Stats

Returns:

Returns the time spent by this node in processing state.

getReadyTime

public long getReadyTime()

Description copied from interface: Stats

The ready time represents the time this node was ready for execution waiting for an available resource.

Specified by:

getReadyTime in interface Stats

Returns:

Returns the time spent by this node in ready state.

getResultsTime

public long getResultsTime()

Description copied from interface: Stats

The results time represents the time since the task is considered finished, and the time the client actually asks (and gets) the result.

Specified by:

getResultsTime in interface Stats

Returns:

Returns the time spent by this tasks in results state.

getTreeSize

public int getTreeSize()

Specified by:

getTreeSize in interface Stats

Returns:

Returns the number of nodes in the tree.

getWaitingTime

public long getWaitingTime()

Description copied from interface: Stats

The waiting time represent the time this node spent waiting for other related nodes to finish. In particular for sub-nodes spawned from this one.

Specified by:

getWaitingTime in interface Stats

Returns:

Returns the time this node spent in waiting state.

getTreeDepth

public float getTreeDepth()

Description copied from interface: Stats

The average depth of the tree, calculated as logB(#Nodes -1), where the base B is the average tree span.

Specified by:

getTreeDepth in interface Stats

Returns:

The average depth of the tree.

getTreeSpan

public float getTreeSpan()

Description copied from interface: Stats

The tree span is the average number of branches of internal tree nodes. It is calculated as: (#Nodes - 1)/(# Inner Nodes).

Specified by:

getTreeSpan in interface Stats

Returns:

Returns the average number of branches of this tree.

getExcercise

public Exercise getExcercise(Muscle muscle)

Specified by:

getExcercise in interface Stats

Returns:

The excercise of the specified muscle, or null if no statistics are available for this muscle.
