All Implemented Interfaces:

Cube<E,T>

Direct Known Subclasses:

MapBasedCube

public abstract class VaryingCube<E,T>
extends AbstractCube<E,T>

Parent class for cube implementations where the dimension (the number of edges) can vary.

Since:

1.1

Constructor Summary

protected	VaryingCube() Constructs a new AbstractCube.
	VaryingCube(List<Set<E>> edgesBase) Constructs a new VaryingCube.

Method Summary

protected void	adjustEdges(List<E> location) Modifies the edgesBase property so that it contains the specified location.
protected List<Set<E>>	getEdgesBase() Returns the edgesBase property.
protected Set<E>	newEdge() Creates a new collection to contain edge values.

Constructor Detail

VaryingCube

public VaryingCube(List<Set<E>> edgesBase)

Constructs a new VaryingCube.

Parameters:

edgesBase - internal list containing the edges

VaryingCube

protected VaryingCube()

Constructs a new AbstractCube.

Method Detail

getEdgesBase

protected List<Set<E>> getEdgesBase()

Returns the edgesBase property. In contrast to AbstractCube.getEdges() this method returns a modifiable handle.

Returns:

the edgeBase property.

newEdge

protected Set<E> newEdge()

Creates a new collection to contain edge values. Used by adjustEdges(List). This implementation returns a HashSet.

Returns:

a new collection to contain edge values.

adjustEdges

protected void adjustEdges(List<E> location)

Modifies the edgesBase property so that it contains the specified location. Intended to be called from AbstractCube.put(java.util.List, T).

• If the size of the specified location is bigger than the size of the edgesBase property, the edgesBase property is enlarged by appending new sets using newEdge().
• Adds the location element of each dimension to the corresponding edgesBase collection.

The edgesBase must only contain sets.

Parameters:

location - a list of index values that determines a position in the cube

Throws:

ClassCastException - if an edge is not a Set.
