Detailed Description

This class represents a Lua object of any type. A LuaObject is constructed by a LuaState object using one of the four methods:

• LuaState#getLuaObject(String globalName)
• LuaState#getLuaObject(LuaObject parent, String name)
• LuaState#getLuaObject(LuaObject parent, Number name)
• LuaState#getLuaObject(LuaObject parent, LuaObject name)
• LuaState#getLuaObject(int index)

The LuaObject will represent only the object itself, not a variable or a stack index, so when you change a string, remember that strings are immutable objects in Lua, and the LuaObject you have will represent the old one.

Proxies

LuaJava allows you to implement a class in Lua, like said before. If you want to create this proxy from Java, you should have a LuaObject representing the table that has the functions that implement the interface. From this LuaObject you can call the createProxy(String implements). This method receives the string with the name of the interfaces implemented by the object separated by comma.
