Constructor Detail

NormalDim

public NormalDim(Space space,
                 java.lang.String dimId,
                 ObsTrigger trig)

Method Detail

connect

public void connect(Cell c,
                    Cell d)
             throws gzz.errors.ZZAlreadyConnectedException

Description copied from interface: Dim

Connect the two cells in this dimension, in order. This method is not allowed to break existing connections.

Specified by:

connect in interface Dim

Overrides:

connect in class SimpleDim

Throws:

gzz.errors.ZZAlreadyConnectedException - If one of the cells is already connected.

disconnect

public void disconnect(Cell c,
                       int dir)

Description copied from interface: Dim

Disconnect the cell in the given direction. It is not an error to disconnect something that is not connected.

Specified by:

disconnect in interface Dim

Overrides:

disconnect in class SimpleDim

applyDelta

public void applyDelta(DimDelta dset)

Description copied from interface: DeltaDim

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

Specified by:

applyDelta in interface DeltaDim

checkpointDelta

public DimDelta checkpointDelta()

Get the changes since previous checkpoint.

Specified by:

checkpointDelta in interface DeltaDim

getDeltaFromZero

public DimDelta getDeltaFromZero()

Description copied from interface: DeltaDim

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

Specified by:

getDeltaFromZero in interface DeltaDim
