Direct Known Subclasses:
Buffer, Collection.Projection, CollectionWrapper, Set
Method Summary
def + (t : A) : Collection[A]
adds "a" from the collection. Useful for chaining.
def ++ (that : Iterable[A]) : Collection[A]
Operator shortcut for addAll.
def += (t : A) : Unit
adds "a" from the collection.
def -= (a : A) : Unit
removes "a" from the collection.
abstract def add (a : A) : Boolean
Adds "a" to the collection, return true if "a" is actually added.
def addAll (i : Iterable[A]) : Boolean
Adds all elements in "i" to the collection, return true if any elements are added.
def hasAll (i : Iterable[A]) : Boolean
Type-safe version of containsAll. * * @author Sean McDirmid
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.
abstract def transform (f : (A) => A) : Boolean
Transforms each element of the collection in-place according to f.
