Class LuaJC

java.lang.Object
  org.luaj.vm2.luajc.LuaJC

All Implemented Interfaces:

LoadState.LuaCompiler

public class LuaJC
extends java.lang.Object
implements LoadState.LuaCompiler

Implementation of LoadState.LuaCompiler which does direct lua-to-java-bytecode compiling.

This requires the bcel library to be on the class path to work as expected. If the library is not found, the default LuaC lua-to-lua-bytecode compiler will be used.

The compiler should be installed as part of globals initialization, and before any scripts or lua code is executed. A typical example is to install it following the globals creation, as in the following:

 LuaValue _G = JsePlatform.standardGlobals();
 LuaJC.install();
 LoadState.load( new ByteArrayInputStream("print 'hello'".getBytes()), "main.lua", _G ).call();
