SimpleDeltaVStreamTexter(SpanMaker spanMaker, Enfilade1D.Maker enfMaker, EnfiladeAligner enfAligner)
Deprecated. EnfiladeAligner should not be provided by Space: it's too complicated and ill-defined for that.

Method Summary

void	applyDelta(ContentDelta m) Apply a delta to this space.
ContentDelta	checkpointDelta() Get the set of changes.
ContentDelta	getDeltaFromZero() Get the set of changes needed to take a CellTexter from zero to the current state of this CellTexter.
protected void	setMap(Cell c, Enfilade1D enf) The innermost routine that uses the actual map.

Method Detail

setMap

protected void setMap(Cell c,
                      Enfilade1D enf)

Description copied from class: SimpleVStreamTexter

The innermost routine that uses the actual map. For keeping change lists etc, override this and getFromMap.

Overrides:

setMap in class SimpleVStreamTexter

checkpointDelta

public ContentDelta checkpointDelta()

Description copied from interface: DeltaCellTexter

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

Specified by:

checkpointDelta in interface DeltaCellTexter

getDeltaFromZero

public ContentDelta getDeltaFromZero()

Description copied from interface: DeltaCellTexter

Get the set of changes needed to take a CellTexter from zero to the current state of this CellTexter.

Specified by:

getDeltaFromZero in interface DeltaCellTexter

applyDelta

public void applyDelta(ContentDelta m)

Description copied from interface: DeltaCellTexter

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

Specified by:

applyDelta in interface DeltaCellTexter
