                    ModularCellTexter cellTexter,
                    CellManager cellManager,

                    Slicer slicer,
                    ObsTrigger obsTrigger)

Create a new ModularSpace and initialize it from a SliceVersion. XXX where would this fit well? Is it a Slicer responsibility? how to do it for slice.0?

The correct thing is to load slice versions by calling slicer.swapIn(sliceId, version). The point is that slice.0 should be always there, i.e. not only after swapIn() is called... maybe the ModularSpace constructor should simply call swapIn(getSlice0())...

Method Detail

getHomeCell

public Cell getHomeCell()

Description copied from interface: Space

Get the home cell of this space. The home cell is where everything begins.

getCell

public Cell getCell(java.lang.String id)

Description copied from interface: Space

Get a cell by its ID.

getDim

public Dim getDim(Cell name)

Description copied from interface: Space

Get a dimension by cell. The same Dim object should be returned when this is called with Cells that are clones of each other.

getDims

public java.util.Set getDims()

Description copied from interface: Space

Get the set of all dimensions in this space.

Returns:

A Set, containing Dim objects for the dimensions in this space.

getIdentity

public Cell getIdentity(java.lang.String s)

Description copied from interface: Space

Get the cell representing a given global identity.

Specified by:

getIdentity in interface Space

Overrides:

getIdentity in class AbstractSpace

getIdentity

public Cell getIdentity(Cell c)

Description copied from interface: Space

Get the canonical cell representing a given cell's global identity.

Specified by:

getIdentity in interface Space

Overrides:

getIdentity in class AbstractSpace

getCloneDim

public Dim getCloneDim()

Description copied from interface: Space

Get the clone dimension of this space.

Specified by:

getCloneDim in interface Space

Specified by:

getCloneDim in class AbstractSpace

N

public Cell N(Cell inSlice)

Description copied from interface: Space

Create a new cell in the same slice as the given cell.

N

public Cell N(Cell inSlice,
              Dim dim,
              int dir,
              Obs o)

Description copied from interface: Space

Create a new cell in the same slice as the given cell, and connect it in the direction given.

Parameters:
