所有已实现的接口:

Globals.Loader

public class LuaJC
extends Object
implements Globals.Loader

Implementation of Globals.Compiler which does direct lua-to-java-bytecode compiling.

By default, when using JsePlatform or org.luaj.vm2.lib.jme.JmePlatform to construct globals, the plain compiler LuaC is installed and lua code will only be compiled into lua bytecode and execute as LuaClosure.

To override the default compiling behavior with LuaJC lua-to-java bytecode compiler, install it before undumping code, for example:

 
 LuaValue globals = JsePlatform.standardGlobals();
 LuaJC.install(globals);
 LuaValue chunk = globals.load( "print('hello, world'), "main.lua");
 System.out.println(chunk.isclosure());  // Will be false when LuaJC is working.
 chunk.call();
  

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.

install

public static final void install(Globals G)

Install the compiler as the main Globals.Loader to use in a set of globals. Will fall back to the LuaC prototype compiler.

                            boolean genmain)
                     throws IOException

抛出:

IOException
