CachedArrayList
public class CachedArrayList extends ArrayList (Code)
	This is a fast access ArrayList that sacrifices memory for speed. It will reduce the speed of indexOf method from O(n) to O(1). However it will at least double the memory used by ArrayList. So use it approriately.

Constructor Summary
public	CachedArrayList()
public	CachedArrayList(Collection<? extends E> c)
public	CachedArrayList(int initialCapacity)

Method Summary
public boolean	add(E o)
public void	add(int index, E element)
public boolean	addAll(Collection<? extends E> c)
public boolean	addAll(int index, Collection<? extends E> c)
protected void	adjustCache(int index, int increase) Adjusts the cache so that all values that are greater than index will increase by the value specified by the increase parameter. Parameters: index - the index.
public void	cacheAll() Cache all the element index.
public void	cacheIt(Object o, int index) Caches the index of the element.
public void	clear()
public int	indexOf(Object elem)
public void	invalidateCache() Invalidated the whole cache.
public boolean	isLazyCaching()
public E	remove(int index)
public boolean	remove(Object o)
public boolean	removeAll(Collection c)
protected void	removeRange(int fromIndex, int toIndex)
public E	set(int index, E element)
public void	setLazyCaching(boolean lazyCaching)
public void	uncacheAll() Uncache the whole cache.
public void	uncacheIt(Object o) Uncaches the index of the element.
