Method Detail

collectionPhase

public final void collectionPhase(short phaseId)

Perform a (global) collection phase.

Specified by:

collectionPhase in class Plan

Parameters:

phaseId - The unique id of the phase to perform.

getPagesUsed

public int getPagesUsed()

Return the number of pages reserved for use given the pending allocation. The superclass accounts for its spaces, we just augment this with the default space's contribution.

Overrides:

getPagesUsed in class Plan

Returns:

The number of pages reserved given the pending allocation, excluding space reserved for copying.

registerSpecializedMethods

protected void registerSpecializedMethods()

Registers specialized methods.

Overrides:
