public interface KTypeCollection<KType>
extends KTypeContainer<KType>

A collection allows basic, efficient operations on sets of elements (difference and intersection).

Method Summary

void	clear() Removes all elements from this collection.
int	removeAll(KTypeLookupContainer<? extends KType> c) Removes all elements in this collection that are present in c.
int	removeAll(KTypePredicate<? super KType> predicate) Removes all elements in this collection for which the given predicate returns true.
int	removeAllOccurrences(KType e) Removes all occurrences of e from this collection.
int	retainAll(KTypeLookupContainer<? extends KType> c) Keeps all elements in this collection that are present in c.
int	retainAll(KTypePredicate<? super KType> predicate) Keeps all elements in this collection for which the given predicate returns true.

Method Detail

removeAllOccurrences

int removeAllOccurrences(KType e)

Removes all occurrences of e from this collection.

Parameters:

e - Element to be removed from this collection, if present.

Returns:

The number of removed elements as a result of this call.

removeAll

int removeAll(KTypeLookupContainer<? extends KType> c)

Removes all elements in this collection that are present in c. Runs in time proportional to the number of elements in this collection. Equivalent of sets difference.

Returns:

Returns the number of removed elements.

removeAll

int removeAll(KTypePredicate<? super KType> predicate)

Removes all elements in this collection for which the given predicate returns true.

retainAll

int retainAll(KTypeLookupContainer<? extends KType> c)

Keeps all elements in this collection that are present in c. Runs in time proportional to the number of elements in this collection. Equivalent of sets intersection.

Returns:

Returns the number of removed elements.

retainAll

int retainAll(KTypePredicate<? super KType> predicate)

Keeps all elements in this collection for which the given predicate returns true.

clear

void clear()

Removes all elements from this collection.
