result of grp.tag

[rocfusion]

Hi,

What is the most efficient way of testing for the table object returned by grp.tag?  ie is it better to test for the existence of the table or the length or is there something else?

Code:

if (event.type=='groupwrite') then  local myvl = grp.tag({'VL0','vl'},'all')  if(myvl) then --existence    myvl:write(event.getvalue())  end  local myls = grp.tag({'VL0','ls'},'all')  if(#myls>0) then  --length    if (event.getvalue() > 0) then      myls:write(true)    else      myls:write(false)    end  end end

Thanks,


Roger
