所有已实现的接口:

Globals.Compiler, Globals.Loader

public class LuaC
extends Constants
implements Globals.Compiler, Globals.Loader

Compiler for Lua.

Compiles lua source files into lua bytecode within a Prototype, loads lua binary files directly into a Prototype, and optionaly instantiates a LuaClosure around the result using a user-supplied environment.

Implements the Globals.Compiler interface for loading initialized chunks, which is an interface common to lua bytecode compiling and java bytecode compiling.

The LuaC compiler is installed by default by both the JsePlatform and org.luaj.vm2.lib.jme.JmePlatform classes, so in the following example, the default LuaC compiler will be used:

 
 Globals globals = JsePlatform.standardGlobals();
 globals.load(new StringReader("print 'hello'"), "main.lua" ).call();
  

To load the LuaC compiler manually, use the install method:

 
 LuaC.install(globals);

方法详细资料

install

public static void install(Globals globals)

Install the compiler so that LoadState will first try to use it when handed bytes that are not already a compiled lua chunk.

参数:

globals - the Globals into which this is to be installed.

compile

public Prototype compile(InputStream stream,
                         String chunkname)
                  throws IOException

Compile lua source into a Prototype.

指定者:

compile 在接口中 Globals.Compiler

参数:

stream - InputStream representing the text source conforming to lua source syntax.

chunkname - String name of the chunk to use.

返回:

Prototype representing the lua chunk for this source.

抛出:

IOException

load

public LuaFunction load(Prototype prototype,
                        String chunkname,
                        Globals globals,
                        LuaValue env)
                 throws IOException

从接口复制的说明: Globals.Loader

Convert the prototype into a LuaFunction with the supplied environment.

指定者:

load 在接口中 Globals.Loader

抛出:

IOException

load

public LuaValue load(InputStream stream,
                     String chunkname,
                     Globals globals)
              throws IOException

已过时。 Use Globals.load(InputString, String, String) instead, or LuaC.compile(InputStream, String) and construct LuaClosure directly.

抛出:

IOException
