LBJ2.infer
Class XpressMPHook.Vector2D

java.lang.Object
  LBJ2.infer.XpressMPHook.Vector2D

Direct Known Subclasses:

XpressMPHook.Vector2DDouble, XpressMPHook.Vector2DInt

Enclosing class:

XpressMPHook

protected static class XpressMPHook.Vector2D
extends java.lang.Object

A two dimensional vector representation implemented here because we are not assuming Java 5. The term sub-vector appearing below refers to the Vector objects which are elements of data.

Field Summary

protected java.util.Vector	data The vector of vectors.
protected int	size The total number of elements in all vectors.

Constructor Summary

XpressMPHook.Vector2D()
Default constructor.

Method Summary

void	add(java.lang.Object element, int index) Adds the specified element to the specified vector.
java.lang.Object	get(int v, int i) Returns the element at the specified position in the 2D vector.
int[]	indexMap() The array returned by this method contains indexes into the arrays returned by XpressMPHook.Vector2DInt.flatten() and XpressMPHook.Vector2DDouble.flatten() indicating where each vector began and ended before they were flattened.
int	size() Returns the total number of elements in all vectors.
int	size(int v) Returns the size of the specified sub-vector.
int	subVectors() Returns the number of vectors contained in data.
java.lang.String	toString() Returns a string representation of this two dimensional vector.

Field Detail

data

protected java.util.Vector data

The vector of vectors.

size

protected int size

The total number of elements in all vectors.

Default constructor.

Method Detail

subVectors

public int subVectors()

Returns the number of vectors contained in data.

size

public int size()

Returns the total number of elements in all vectors.

size

public int size(int v)

Returns the size of the specified sub-vector.

Parameters:

v - The index of a sub-vector.

Returns:

The number of elements in sub-vector v.

add

public void add(java.lang.Object element,
                int index)

Adds the specified element to the specified vector. If the specified vector does not exist, new vectors are added until it does.

Parameters:

element - The element to add.

index - The index of the vector to which element should be added.

get

public java.lang.Object get(int v,
                            int i)

Returns the element at the specified position in the 2D vector.

Parameters:

v - The index of the sub-vector in which to look.

i - The index of the element in vector v.

Returns:

The element at the specified position.

indexMap

public int[] indexMap()

The array returned by this method contains indexes into the arrays returned by XpressMPHook.Vector2DInt.flatten() and XpressMPHook.Vector2DDouble.flatten() indicating where each vector began and ended before they were flattened.

toString

public java.lang.String toString()

Returns a string representation of this two dimensional vector.

Overrides:

toString in class java.lang.Object
