org.jikesrvm.adaptive.measurements.organizers.MethodSampleOrganizer

public final class MethodSampleOrganizer
extends Organizer

An organizer for method listener information.

This organizer is designed to work well with non-decayed cumulative method samples. The basic idea is that each time the sampling threshold is reached we update the accumulated method sample data with the new data and then notify the controller of all methods that were sampled in the current window.
