Examples of org.luaj.vm2.Varargs

org.luaj.vm2.lib.OneArgFunction
Class to encapsulate varargs values, either as part of a variable argument list, or multiple return values.
To construct varargs, use one of the static methods such as {@code LuaValue.varargsOf(LuaValue,LuaValue)}

Any LuaValue can be used as a stand-in for Varargs, for both calls and return values. When doing so, nargs() will return 1 and arg1() or arg(1) will return this. This simplifies the case when calling or implementing varargs functions with only 1 argument or 1 return value.
Varargs can also be derived from other varargs by appending to the front with a call such as {@code LuaValue.varargsOf(LuaValue,Varargs)}or by taking a portion of the args using {@code Varargs.subargs(int start)}
