Class FunctionUtils.UnmodifiableCollection<T>

java.lang.Object

org.organicdesign.fp.FunctionUtils.UnmodifiableCollection<T>

All Implemented Interfaces:

Serializable, Iterable<T>, Collection<T>, Sized, UnmodCollection<T>, UnmodIterable<T>, Transformable<T>

Enclosing class:

FunctionUtils

public static class FunctionUtils.UnmodifiableCollection<T>
extends Object
implements UnmodCollection<T>, Serializable

Wraps a collection. The result will be serializable to the extent that the wrapped collection is. You probably want to use this by calling FunctionUtils.unmodCollection(Collection) (also see caveats there).

Specified by:

size in interface Sized

isEmpty

public boolean isEmpty()

Description copied from interface: UnmodCollection

iterator

public UnmodIterator<T> iterator()

Description copied from interface: UnmodCollection

An unmodifiable iterator A one-time use, mutable, not-thread-safe way to get each value of the underling collection in turn. I experimented with various thread-safe alternatives, but the JVM is optimized around iterators so this is the lowest common denominator of collection iteration, even though iterators are inherently mutable.
