All Implemented Interfaces:: Constants

public class StickyImmixCollector
extends ImmixCollector
extends ImmixCollector

This class implements per-collector thread behavior and state for the StickMS plan, which implements a generational sticky mark bits immix collector.

Specifically, this class defines StickyMS collection behavior (through trace and the collectionPhase method).

Method Detail

collectionPhase

public final void collectionPhase(short phaseId,
                                  boolean primary)

Perform a (local, i.e.per-collector) collection phase.

Overrides:: collectionPhase in class ImmixCollector

Parameters:: phaseId - The unique phase identifier; primary - Should this thread be used to execute any single-threaded local operations?

global

private static StickyImmix global()

Returns:: The active global plan as an StickyImmix instance.
