org.cojen.tupl.util.Canonicalizer

public final class Canonicalizer
extends Object

Implements a specialized cache for supporting object canonicalization. It behaves like the String.intern method, but this class supports any kind of object.

Objects that do not customize the hashCode and equals methods don't make sense to be canonicalized because each instance will be considered unique. The object returned from the apply method will always be the same as the one passed in.
