Method Detail

checkpointDelta

public Delta checkpointDelta()

Description copied from interface: DeltaSpace

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

Specified by:

checkpointDelta in interface DeltaSpace

getDeltaFromZero

public Delta getDeltaFromZero()

Description copied from interface: DeltaSpace

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

Specified by:

getDeltaFromZero in interface DeltaSpace

applyDelta

public void applyDelta(Delta delta)

Description copied from interface: DeltaSpace

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

Note: calling applyDelta may throw InconsistentChangeException, in which case the state of the space is undefined.

Specified by:

applyDelta in interface DeltaSpace
