Modifier and Type	Class	Description
static class	CellLattice.NeighborIterator	Extends the SimpleLattice neighbor iterator to provide methods that specify the neighbor range in terms of a distance, rather than an index range.

Constructor Detail

CellLattice

public CellLattice(Space space,
                   Vector dimVector,
                   SiteFactory factory)

Parameters:

dimVector - the spatial dimensions of the lattice, such that the total space occupied by the lattice cells a rectangular box with each side of length dimensions.x(i)/size[i] for side i. The dimensions at any time are given by the array passed here, so any changes to the array external to this class will result in a change in the dimensions of this lattice (this is useful in resizing the lattice to the dimensions of a box, by giving a reference to box.boundary().dimension() here). The dimensions array reference is final and cannot be changed . The lattice dimension D is given by dimensions.length.

Method Detail

site

public java.lang.Object site(Vector r)

Returns the cell in which the given point lies. An ArrayIndexOutOfBounds exception is thrown if the point lies outside the bounds of the lattice (less than zero or greater than dimensions). The dimension of the vector is assumed to be consistent with the dimension D of the lattice (i.e., r.D() == this.D()) but this is not checked.

getDimensions

public Vector getDimensions()

Returns the array that specifies the spatial dimensions of the lattice of cells.

setDimensions

public void setDimensions(Vector d)

getCellSize

public double[] getCellSize()

Returns the spatial dimensions of all cells in the lattice, such that a cell in the lattice will have a size in each direction as given by the corresponding value in the returned array. Value is computed on-the-fly using current value of dimensions and size.
