Package com.palantir.common.collect

Class IterableView<T>

java.lang.Object

com.google.common.collect.ForwardingObject

com.palantir.common.collect.IterableView<T>

All Implemented Interfaces:

Iterable<T>

public abstract class IterableView<T>
extends com.google.common.collect.ForwardingObject
implements Iterable<T>

A wrapper for an iterable that gives it super chaining powers. And a nice toString.

immutableCopy

public com.google.common.collect.ImmutableList<T> immutableCopy()

Returns an immutable copy of the current contents of this iterable view. Does not support null elements.
