DimManager

All Known Implementing Classes:

AbstractDeltaDimManager

public interface DeltaDimManager

extends DimManager

The dimensions of a DeltaSpace. Supports the same operations as DeltaSpace (with different parameters)

static java.lang.String

rcsid

Method Summary

void	applyDelta(java.util.Map m) Apply a delta to this space.
java.util.Map	checkpointDelta() Get the set of changes.
java.util.Map	getDeltaFromZero() Get the set of changes needed to take a set of Dimensions from zero to the current state of this DimManager's dimensions.

Method Detail

checkpointDelta

public java.util.Map checkpointDelta()

Get the set of changes. Returns the changes since a previous getDelta in a Delta object.

getDeltaFromZero

public java.util.Map getDeltaFromZero()

Get the set of changes needed to take a set of Dimensions from zero to the current state of this DimManager's dimensions.

applyDelta

public void applyDelta(java.util.Map m)

Apply a delta to this space. Also triggers observers. However, a change applied by applyDelta is NOT visible in the next getDelta().
