static public<A> Set<A> metadone.util.SetUtil.add	(	Set< A >	s,
		A	a
	)		[static, package]

Parameters:

<A>
s	a set, not null
a	an element

Returns:

the set s with element a included

static public<T extends Object> HashSet<T> metadone.util.SetUtil.array2HashSet

(

T[]

array

)

[static, package]

Convert an array into an hashset. If the array is null, the result is an empty set. Null elements of the array are thrown away of the result.

Parameters:

array

an array of type T

Returns:

an hashset of type T

static public<T extends Object> String metadone.util.SetUtil.convertToString

(

Set< T >

set

)

[static, package]

Parameters:

<T>
set

Returns:

A string that denotes the argument.

static public<T extends Object> Set<T> metadone.util.SetUtil.diff	(	Set< T >	a,
		Set< T >	b,
		Set< T >	c
	)		[static, package]

Compute C as A

Parameters:

<T>
a	not null
b	not null
c	if c is null, an hashset is created for the result.

Returns:

c

static public<T extends Object> HashSet<T> metadone.util.SetUtil.filter	(	Set< T >	myset,
		Criteria< T >	criteria
	)		[static, package]

Parameters:

<T>	any type
myset	a set of T. Can be null.
criteria	A not null criteria that denotes a predicate

Returns:

a set with all the elements of myset that meets the predicate.

static public<T extends Object> T metadone.util.SetUtil.getOneOf

(

Set< T >

s

)

[static, package]

Parameters:

<T>
s	can be null

Returns:

One random element of the s set and null if the set is empty or null.

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

Computes C as A intersection with B.

Parameters:

<T>
a	not null
b	not null
c	if c is null, a new hashset is created.

Returns:

c

static boolean metadone.util.SetUtil.isDisjoined	(	Set<?>	a,
		Set<?>	b
	)		[static]

Uses the Object#equals(Object) method to test if there is no common member.

Parameters:

<T>
a	not null
b	not null

Returns:

true iff sets a and b are disjoined.

static public<B, A> HashSet<A> metadone.util.SetUtil.mapset	(	final Set< B >	set,
		final MapFct< B, A >	map
	)		[static, package]

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

Parameters:

<B>
<A>
set
map

Returns:

static public<T extends Object> Set<T> metadone.util.SetUtil.union	(	Set< T >	a,
		Set< T >	b,
		Set< T >	c
	)		[static, package]

Computes C as A+B

Parameters:

<T>
a	not null
b	not null
c	if c is null, a new hashset is created.

Returns:

C
