trait IterableForwarder
[source: scala/collection/generic/IterableForwarder.scala]
trait IterableForwarder[+A]
extends Iterable[A] with TraversableForwarder[A]

This trait implements a forwarder for iterable objects. It forwards all calls to a different iterable object, except for

The above methods are forwarded by subclass IterableProxy.

Method Summary
override def iterator : Iterator[A]

override def sameElements [B >: A](that : Iterable[B]) : Boolean
Checks if the other iterable object contains the same elements as this one.

Method Details
protected abstract def underlying : Iterable[A]
The iterable object to which calls are forwarded
Overrides
TraversableForwarder.underlying
override def iterator : Iterator[A]
Creates a new iterator over all elements contained in this iterable object.
Returns
the new iterator
override def sameElements[B >: A](that : Iterable[B]) : Boolean
Checks if the other iterable object contains the same elements as this one.
Notes
will not terminate for infinite-sized iterables.
Might return different results for different runs, unless this iterable is ordered
Parameters
that - the other iterable
Returns
true, iff both iterables contain the same elements.
