All Implemented Interfaces:

Cube<E,T>

public class CubeProxy<E,T>
extends AbstractCube<E,T>

A proxy of an underlying cube. This class is used as a default for projections in AbstractCube.getProjection(int, E).

Since:

1.1

Constructor Summary

CubeProxy(Cube<E,T> base)
Creates a new CubeProxy of the specified base cube.

Method Summary

T	get(List<E> location) Returns the element at the specified location.
List<Collection<? extends E>>	getEdges() Returns the possible index values of each dimension.
protected List<E>	getOrigin(List<E> location) Calculates the location in the base cube.
Cube<E,T>	getProjection(int index, E pivot) Returns a projection of this cube.
void	put(List<E> location, T value) Sets the element at the specified location to the specified value.

Constructor Detail

CubeProxy

public CubeProxy(Cube<E,T> base)

Creates a new CubeProxy of the specified base cube.

Parameters:

base - the base cube

Method Detail

getEdges

public List<Collection<? extends E>> getEdges()

Description copied from class: AbstractCube

Returns the possible index values of each dimension. Each element of the returned list is a collection that contains all possible values for the dimension corresponding to the index in the list. This implementation returns the edges property.

Specified by:

getEdges in interface Cube<E,T>

Overrides:

getEdges in class AbstractCube<E,T>

Returns:

the possible index values of each dimension.

getOrigin

protected List<E> getOrigin(List<E> location)

Calculates the location in the base cube.

Parameters:

location - location in this projection

Returns:

the location in the base cube.

Throws:

NullPointerException - specified location is null.

get

public T get(List<E> location)

Description copied from class: AbstractCube

Returns the element at the specified location.

Specified by:

get in interface Cube<E,T>

Specified by:

get in class AbstractCube<E,T>

Parameters:

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

Returns:

the element at the specified location.

put

public void put(List<E> location,
                T value)

Description copied from class: AbstractCube

Sets the element at the specified location to the specified value.

Specified by:

put in interface Cube<E,T>

Specified by:

put in class AbstractCube<E,T>

Parameters:

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

value - new value of the cell at the specified location

getProjection

public Cube<E,T> getProjection(int index,
                               E pivot)

Description copied from class: AbstractCube

Returns a projection of this cube. This implementation creates a CubeProxy of this object and calls the corresponding method of the proxy.

Specified by:

getProjection in interface Cube<E,T>

Overrides:

getProjection in class AbstractCube<E,T>

Parameters:

index - the dimension that will be fixed.

pivot - the fixed value of the fixed dimension.

Returns:

a projection of this cube.
