removeIf

public boolean removeIf(Predicate<? super T> predicate)

Description copied from interface: MutableCollection

Removes all elements in the collection that evaluate to true for the specified predicate.

e.g.
return lastNames.removeIf(Predicates.isNull());

Specified by:

removeIf in interface FixedSizeCollection<T>

Specified by:

removeIf in interface MutableCollection<T>

Overrides:

removeIf in class AbstractMutableCollection<T>

public <P> boolean removeIfWith(Predicate2<? super T, ? super P> predicate,

withAll

public MutableSet<T> withAll(Iterable<? extends T> elements)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to add multiple elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new elements to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

MutableCollection<String> list = list.withAll(FastList.newListWith("1", "2"));

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling addAll on itself.

withoutAll

public MutableSet<T> withoutAll(Iterable<? extends T> elements)

Description copied from interface: MutableCollection

This method allows mutable and fixed size collections the ability to remove multiple elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned containing the elements that would be left from the original collection after calling removeAll. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:

MutableCollection<String> list = list.withoutAll(FastList.newListWith("1", "2"));

In the case of FixedSizeCollection a new instance of MutableCollection will be returned by withoutAll, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling removeAll on itself.

tap

public FixedSizeSet<T> tap(Procedure<? super T> procedure)
