public class Bit32Lib
extends TwoArgFunction

Subclass of LibFunction that implements the Lua standard bit32 library.

Typically, this library is included as part of a call to either

 
 Globals globals = JsePlatform.standardGlobals();
 System.out.println( globals.get("bit32").get("bnot").call( LuaValue.valueOf(2) ) );
  

To instantiate and use it directly, link it into your globals table via LuaValue.load(LuaValue) using code such as:

 
 Globals globals = new Globals();
 globals.load(new JseBaseLib());
 globals.load(new PackageLib());
 globals.load(new Bit32Lib());
 System.out.println( globals.get("bit32").get("bnot").call( LuaValue.valueOf(2) ) );
  

This has been implemented to match as closely as possible the behavior in the corresponding library in C.

Method Details

call

public LuaValue call(LuaValue modname,
 LuaValue env)

Perform one-time initialization on the library by creating a table containing the library functions, adding that table to the supplied environment, adding the table to package.loaded, and returning table as the return value.

Specified by:

call in class TwoArgFunction

Parameters:

modname - the module name supplied if this is loaded via 'require'.

env - the environment to load into, which must be a Globals instance.

Returns:

First return value (this(arg1,arg2)), or LuaValue.NIL if there were none.
