Package party.iroiro.luajava

Class ClassPathLoader

java.lang.Object
party.iroiro.luajava.ClassPathLoader
All Implemented Interfaces:
ExternalLoader
public class ClassPathLoader extends Object implements ExternalLoader
An ExternalLoader that loads modules from classpath

The path to the resource is converted from module name with getPath(String). For example, loading a abc.def module will load a Lua file at classpath://abc/def.lua.

To use this class, call Lua.setExternalLoader(ExternalLoader) with an instance of this class, and then you can load modules with the Lua require function from classpath.
