static public<T extends Object> List<T> metadone.util.ListUtil.intersect	(	List< T >	a,
		List< T >	b,
		List< T >	c
	)		[static, package]

Parameters:

<T>
a
b
c	List c is used to store the result. List c is supposed to be empty and initialized. If c is null, a new linkedlist is created.

Returns:

The common elements of lists 'a' and 'b'. List 'c' is used as the result and is returned.

static public<B, A> LinkedList<A> metadone.util.ListUtil.maplist	(	final List< B >	list,
		final MapFct< B, A >	map
	)		[static, package]

Converts a list into another list by mapping every element with the map function.

Parameters:

<B>
<A>
