Checking for Out Links with DOORS DXL - ibm-doors

Question

I am trying to write a simple DXL that checks for out links. More specifically, I want to look through every requirement in a formal module and return the number of items missing an out link:
Module m = current
Object o = null
string objType = ""
Link outLink
int noOutLinkCount = 0
for o in m do {
objType = o."Object Type"
for outLink in o -> "*" do {
if objType == "Req" or objType = "Obj" and outLink == null then noOutLinkCount++
}
}
print "No Out Link Count = " noOutLinkCount""
For the life of me, I cannot figure out how to do this. The condition
outLink == null
does not seem to work.
Note: Checking to make sure the object is of type "Req" (Requirement) or "Obj" (Objective Requirement) is necessary as I do not care about missing links on Headers, images, text objects, etc.

Answer 1

This loop:
for outLink in o -> "*" do {
}
Will execute for each outlink. It will not execute at all if there are 0 outlinks.
I would structure the code like so:
Module m = current
Object o = null
string objType = ""
Link outLink
int noOutLinkCount = 0
for o in m do {
objType = o."Object Type" ""
// Check if the type is right
if ( ( objType == "Req" ) || ( objType == "Obj" ) ) {
// Check for any outlinks at all
bool no_outlink_flag = true
for outLink in o -> "*" do {
// If this executes, at least 1 outlink- flag and break
no_outlink_flag = false
break
}
// If we didn't flag any outlinks, increment
if ( no_outlink_flag ) {
noOutLinkCount++
}
}
}
print "No Out Link Count = " noOutLinkCount""
That should work. Let me know if it does!
