public class ClassCache

extends Object

Untamed: A performance optimizing hack: by hanging onto classes that are looked up by name, we can spare Java's overhead if they ever have to be looked up again.

Also recognizes the names for the scalar types and "void".

XXX The original motivation -- the surprising overhead of Java's Class.forName(String) may have been long fixed, in which case this implementation should do less.

ClassCache() prevent instantiation

Method Summary

static Class

forName(String name) Enabled: Like Class.forName(String), but also accepts the string-names for the scalar types and "void".
