[source: scala/collection/jcl/MutableIterable.scala]
trait MutableIterable[A]
extends Collection[A]
An iterable collection that supports remove operations. Useful for representing projections of mutable collections that where only the remove operation makes sense.

Direct Known Subclasses:
Collection, IterableWrapper, Map, MutableIterable.Projection, MutableSeq, Ranged
Method Summary
def - (t : A) : MutableIterable[A]
def -- (that : Iterable[A]) : MutableIterable[A]
Operator shortcut for removeAll.
def clear : Unit
clear all elements from the collection.
override abstract def elements : MutableIterator[A]
The default implementation of a map over mutable iterable collections.
def has (t : A) : Boolean
override def projection : Projection[A]
returns a projection that can be used to call non-strict filter, map, and flatMap methods that build projections of the collection.
def remove (t : A) : Boolean
def removeAll (that : Iterable[A]) : Boolean
def retainAll (that : Iterable[A]) : Boolean
retain only elements that are also in that.
def retainOnly (p : (A) => Boolean) : Unit
retain only elements in the collection that predicate p is true for.

Returns
the current number of elements in the collection.
def clear : Unit
clear all elements from the collection.
override def projection : Projection[A]
