Class ImmutableLinkedHashSet<E>

java.lang.Object

net.nicholaswilliams.java.licensing.immutable.ImmutableAbstractCollection<E>

net.nicholaswilliams.java.licensing.immutable.ImmutableLinkedHashSet<E>

All Implemented Interfaces:

Serializable, Cloneable, Iterable<E>, Collection<E>, Set<E>, Immutable

public final class ImmutableLinkedHashSet<E>
extends ImmutableAbstractCollection<E>
implements Set<E>, Serializable, Cloneable

Wraps a set such that it cannot be modified. There is some overhead associated with this due to verification of hash codes on every call to prevent tampering with via reflection, but this is well worth it if your goal is security and you truly need an unmodifiable set.
