类 JsePlatform

java.lang.Object

org.luaj.vm2.lib.jse.JsePlatform

public class JsePlatform
extends Object

The JsePlatform class is a convenience class to standardize how globals tables are initialized for the JSE platform.

It is used to allocate either a set of standard globals using standardGlobals() or debug globals using debugGlobals()

A simple example of initializing globals and using them from Java is:

 
 Globals globals = JsePlatform.standardGlobals();
 globals.get("print").call(LuaValue.valueOf("hello, world"));
  

Once globals are created, a simple way to load and run a script is:

 
 globals.load( new FileInputStream("main.lua"), "main.lua" ).call();
  

although require could also be used:

 
 globals.get("require").call(LuaValue.valueOf("main"));
  

For this to succeed, the file "main.lua" must be in the current directory or a resource. See JseBaseLib for details on finding scripts using ResourceFinder.

The standard globals will contain all standard libraries plus luajava:

• Globals
• JseBaseLib
• PackageLib
• Bit32Lib
• TableLib
• StringLib
• CoroutineLib
• JseMathLib
• JseIoLib
• JseOsLib
• LuajavaLib

In addition, the LuaC compiler is installed so lua files may be loaded in their source form.

The debug globals are simply the standard globals plus the debug library DebugLib.

The class ensures that initialization is done in the correct order.

standardGlobals

public static Globals standardGlobals()

Create a standard set of globals for JSE including all the libraries.

返回:

Table of globals initialized with the standard JSE libraries

debugGlobals

public static Globals debugGlobals()

Create standard globals including the DebugLib library.

返回:

Table of globals initialized with the standard JSE and debug libraries

另请参阅:

standardGlobals(), JsePlatform, org.luaj.vm2.lib.jme.JmePlatform, DebugLib

luaMain

public static Varargs luaMain(LuaValue mainChunk,
                              String[] args)

Simple wrapper for invoking a lua function with command line arguments. The supplied function is first given a new Globals object, then the program is run with arguments.
