Examples of org.luaj.vm2.LuaValue$ArrayVarargs

org.luaj.vm2.LuaValue
Varargs implemenation backed by an array of LuaValues
This is an internal class not intended to be used directly. Instead use the corresponding static methods on LuaValue. @see LuaValue#varargsOf(LuaValue[]) @see LuaValue#varargsOf(LuaValue[],Varargs)
