Examples of LuaFunction

org.luaj.vm2.LuaFunction
Base class for functions implemented in Java.
Direct subclass include {@link LibFunction} which is the base class for all built-in library functions coded in Java, and {@link LuaClosure}, which represents a lua closure whose bytecode is interpreted when the function is invoked. @see LuaValue @see LibFunction @see LuaClosure
