Class SortedArraySet<T>

java.lang.Object

org.apache.cxf.common.util.SortedArraySet<T>

Type Parameters:

T -

All Implemented Interfaces:

java.lang.Iterable<T>, java.util.Collection<T>, java.util.Set<T>, java.util.SortedSet<T>

public final class SortedArraySet<T>
extends java.lang.Object
implements java.util.SortedSet<T>

This class implements most of the Set interface, backed by a sorted Array. This makes iterators very fast, lookups are log(n), but adds are fairly expensive. This class is also threadsafe, but without synchronizations. Lookups and iterators will iterate over the state of the Set when the iterator was created. If no data is stored in the Set, it uses very little memory. The backing array is created on demand. This class is primarly useful for stuff that will be setup at startup, but then iterated over MANY times during runtime.
