Examples of org.luaj.vm2.Prototype

org.luaj.vm2.LuaTable
Prototype representing compiled lua code.
This is both a straight translation of the corresponding C type, and the main data structure for execution of compiled lua bytecode.
See documentatation on {@link LuaClosure} for information on how to load and execute a {@link Prototype}. @see LuaClosure
