Class Vec2fCollection

java.lang.Object
  net.java.joglutils.msg.collections.Vec2fCollection

public class Vec2fCollection
extends Object

Provides the abstraction of a collection of Vec2f objects while allowing access to the backing store in the form of a direct FloatBuffer to make it easy to pass down to OpenGL.

Constructor Summary

Vec2fCollection()
Creates an empty Vec2fCollection.

Vec2fCollection(int estimatedSize)
Creates an empty Vec2fCollection with the backing store sized to hold roughly the given number of vectors.

Method Summary

void	add(Vec2f value) Adds the given Vec2f to this collection, expanding it if necessary.
Vec2f	get(int index) Fetches the Vec2f at the given index.
FloatBuffer	getData() Returns the backing buffer of this collection.
Vec2f	remove(int index) Removes the given Vec2f from this collection.
void	set(int index, Vec2f value) Stores the given Vec2f at the given index.
int	size() Returns the number of Vec2fs currently in this collection.

Constructor Detail

Vec2fCollection

public Vec2fCollection()

Creates an empty Vec2fCollection.

Vec2fCollection

public Vec2fCollection(int estimatedSize)

Creates an empty Vec2fCollection with the backing store sized to hold roughly the given number of vectors.

Method Detail

size

public int size()

Returns the number of Vec2fs currently in this collection.

set

public void set(int index,
                Vec2f value)
         throws IndexOutOfBoundsException

Stores the given Vec2f at the given index. If the collection has not grown to the given size, throws an exception.

Throws:

IndexOutOfBoundsException

get

public Vec2f get(int index)
          throws IndexOutOfBoundsException

Fetches the Vec2f at the given index. If the collection has not grown to the given size, throws an exception.

Throws:

IndexOutOfBoundsException

add

public void add(Vec2f value)

Adds the given Vec2f to this collection, expanding it if necessary.

remove

public Vec2f remove(int index)
             throws IndexOutOfBoundsException

Removes the given Vec2f from this collection. Moves all Vec2fs above it down one slot.

Throws:

IndexOutOfBoundsException

getData

public FloatBuffer getData()

Returns the backing buffer of this collection.
