mergesort flow round robin

Hi,

Is it possible to made the output of mergesort as round robin?? I tried to copy and paste the round robin template code to a merge sort flow but it doesnt work

This is working for me:

MergeSortFlow / Send Requirement
treenode curlabel = label(current,"f_cursendport");if( ! objectexists(curlabel) )
{
curlabel = addlabel( current, "f_cursendport" );
setlabelnum(current, "f_cursendport", 1);
}
if( getoutput(current)==0 && getrank(item)==1 ) setnodenum(curlabel,1); //reset round robin counter if first part
double returnvalue = getnodenum(curlabel);
return returnvalue == port;

Trigger OnExit
treenode curlabel = label(current,"f_cursendport");
double returnvalue = getnodenum(curlabel);
inc(curlabel, 1);
if(getnodenum(curlabel) > nrop( current ))
setnodenum(curlabel, 1);

I guess your problem was that you did not divide the code into two sections and just used the MergeSortFlow and therefore the increment of the label was fired to often.
As you can see I also just copied the round robin template and modified it a bit.

Before i got the solution from Tom, I used a stupid method to solve as I want to distribute item to outport evenly

In Mergesort flow i typed :


int value = duniform(1,4);

switch(port){
/**/
case 1: return value == 1;
case 2: return value == 2;
case 3: return value == 3;
case 4: return value == 4;
default: return 1;/**/
}

return 1;
