Method Detail

index

public static int index(int[] aStructure,
                        int[] aReference)

Parameters:

aStructure - An access structure

aReference - An access element reference

Returns:

The index of that element

size

public static int size(int[] aStructure)

Parameters:

aStructure - An access structure

Returns:

The size of an access with that structure

size

public static int size(int[] aStructure,
                       int aDimension)

Parameters:

aStructure - An access structure

aDimension - A dimension index

Returns:

The size of that dimension

step

public static int step(int[] aStructure,
                       int aDimension)

Parameters:

aStructure - An access structure

aDimension - A dimension index indication a direction

Returns:

The step size (index change) in that direction

step

public static int step(int[] aStructure,
                       int[] aReferenceIncrement)

A more complex/general version of step(int[], int).

Parameters:

aStructure - An access structure

aReferenceIncrement - A vector indication a direction (and size)

Returns:

The step size (index change)
