Class IdentityMostlySingletonSet<T>

java.lang.Object
org.plumelib.util.AbstractMostlySingletonSet<T>
org.plumelib.util.IdentityMostlySingletonSet<T>
Type Parameters:
T - the type of elements of the set
All Implemented Interfaces:
Iterable<T>, Collection<T>, Set<T>
public final class IdentityMostlySingletonSet<T> extends AbstractMostlySingletonSet<T>
An arbitrary-size set that is very efficient (more efficient than HashSet) for 0 and 1 elements. Uses object identity for object comparison.

Usually, you should use IdentityArraySet instead. The advantage of this over IdentityArraySet is that this is efficient for large sets.
