ElapsedTimeCollector

public ElapsedTimeCollector()

Constructs a collector for recording the elapsed execution time of an algorithm.

Method Details

collect

public void collect(Observation observation)

Description copied from interface: Collector

Collects the requested information from the object, storing the data to the specified observation. This method must only be invoked after this collector has been attached to an appropriate object.

Specified by:

collect in interface Collector

Parameters:

observation - the observation to which the collected data is stored

getAttachPoint

public AttachPoint getAttachPoint()

Description copied from interface: Collector

Returns the attach point describing where this collector is attached. The matched object should be unique.

Specified by:

getAttachPoint in interface Collector

Returns:

the attach point describing where this collector is attached

attach

public Collector attach(Object object)

Description copied from interface: Collector

Returns a new instance of this collector which has been attached to the specified object as identified by the attach point returned through Collector.getAttachPoint().

Specified by:

attach in interface Collector

Parameters:

object - the matching object

Returns:

a new instance of this collector which has been attached to the specified object

getElapsedTime

public static double getElapsedTime(Observation observation)

Reads the elapsed time value from the observation.

Parameters:

observation - the observation

Returns:

the elapsed time value.
