RuntimeCollectorExtension

public RuntimeCollectorExtension(ResultFileWriter writer,
 int frequency,
 FrequencyType frequencyType)

Constructs a new wrapper to collect runtime dynamics.

Parameters:

writer - the result file writer where the runtime information is stored

frequency - the frequency at which the runtime snapshots are recorded

Overrides:

onRegister in class PeriodicExtension

Parameters:

algorithm - the algorithm associated with this extension

doAction

public void doAction(Algorithm algorithm)

Description copied from class: PeriodicExtension

The action that is called by this extension.

Specified by:

doAction in class PeriodicExtension

Parameters:

algorithm - the algorithm associated with this extension
