Class Varargs

java.lang.Object
  org.luaj.vm2.Varargs

Direct Known Subclasses:

LuaValue, TailcallVarargs

public abstract class Varargs
extends java.lang.Object

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 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 LuaValue.varargsOf(LuaValue,Varargs) or by taking a portion of the args using Varargs.subargs(int start)

See Also:

LuaValue.varargsOf(LuaValue[]), LuaValue.varargsOf(LuaValue, Varargs), LuaValue.varargsOf(LuaValue[], Varargs), LuaValue.varargsOf(LuaValue, LuaValue, Varargs), LuaValue.varargsOf(LuaValue[], int, int), LuaValue.varargsOf(LuaValue[], int, int, Varargs), subargs(int)
