The variadic class interface accepts < tt class = "computeroutput" >< span class = "number" > 0</ span ></ tt >
to < tt class = "computeroutput" >< span class = "identifier" > FUSION_MAX_SET_SIZE</ span ></ tt > elements,
where < tt class = "computeroutput" >< span class = "identifier" > FUSION_MAX_SET_SIZE</ span ></ tt >
is a user definable predefined maximum that defaults to < tt class = "computeroutput" >< span class = "number" > 10</ span ></ tt > .
2007-11-25 18:38:02 +00:00
