forward

Forwards its argument list preserving $(D_KEYWORD ref) and $(D_KEYWORD out) storage classes.

$(D_PSYMBOL forward) accepts a list of variables or literals. It returns an argument list of the same length that can be for example passed to a function accepting the arguments of this type.

template forward (

args...

) {

alias forward = AliasSeq!();

alias forward = args[0];

alias forward = AliasSeq!(args[0], forward!(args[1..$]));

static if(!(args.length == 0))
static if(!(__traits(isRef, args[0]) || __traits(isOut, args[0])))

auto forwardOne [@property getter];

alias forward = forwardOne;

alias forward = AliasSeq!(forwardOne, forward!(args[1..$]));

}
