ClassLoader Class Reference

#include <coherence/lang/ClassLoader.hpp>

Inherits Object.

Inherited by SystemClassLoader [virtual].

List of all members.


Detailed Description

ClassLoader provides a mechanism for obtaining a Class object.

Classes may be manually registered with a loader, or the loader may search out classes using custom search and load mechanisms.

Not all classes are required to have a corresponding Class representation.

The simplest way to enable a Class to be looked up by name, is to register it with the system ClassLoader, which can be obtained by calling ClassLoader::getSystemClassLoader(). For classes which include a no parameter static create method, a utility macro can be used to generate and register a Class automatically. For example, given the class Foo:

COH_REGISTER_TYPED_CLASS(Foo)

Will register a Class for Foo. This registration would normally occur in Foo.cpp, outside of any method.
