Script to determine if a child object exists under a child object.

I have seen some modules that have a parent object, and each object underneath the parent, all child objects, are under each preceding object.

For example
Parent
Child

Parent
    Child1
        Child2
            Child3
                Child4

Where Child1 is the "parent" of Child2, Child2 is the "parent" of Child3, etc.

Parent
    Child1
        Child2
            Child3
                Child4

Hi,

You can use the "parent" function:

if (Child1 == parent(child2)) {
etc...
}

Hi,

you can iterate over the child objects of an object using:

for Object in Object do { ... }

you can access the n-th child of an object using

Object = Object[n]

e.g.:
 

Object o = current 
 
Object oChild; 
 
// This loop will respect the current display set, e.g. filters, show deleted objects, etc. 
for oChild in o do { print "Found child: " (identifier oChild) "\n" }
 
// This loop will not respect the display set
for oChild in all o do {
  if (isDeleted oChild) continue // skip over deleted objects
  print "Found non deleted child: " (identifier oChild) "\n"
}
 
// This will again respect the display set, e.g. filters, ...
print "The 2nd visible child of the current object is: " (identifier o[2]) "\n"

I think you are asking that you want to find this structure...

• Parent1
  • Child1
    • Child2
  • Child3

... when it should look like this:

• Parent1
  • Child1
  • Child2
  • Child3

If that is so... let me translate it: You want to find each object that is not qualified to be a "parent" and yet they indeed have child objects. Implementing that translation will result in this report:

• "Object Child1 had a child object but is not a parent object".

Let me scibble:

bool  IsLegalParent(Object o)
{    // Determine if this object qualifies as a "Parent".
     // Not sure what this means for you, but perhaps:
    string Heading = o."Object Heading"
    return(!null Heading)
}   // end IsLegalParent()
 
bool  IsParent_Legal, IsParent_Actual
Object o
Module mod = current()
for o in entire mod do
{  if (isDeleted(o))     continue
   IsParent_Legal  = IsLegalParent(o)
   IsParent_Actual = !null o[1]     // Is there a child object?
   if     ( IsParent_Legal and  IsParent_Actual) then{}  // No Problem
   elseif( IsParent_Legal and !IsParent_Actual) then {error, Parent has no children}
   elseif(!IsParent_Legal and  IsParent_Actual) then {error, Child has child objects}
   elseif(!IsParent_Legal and !IsParent_Actual) then {}  // no problem
   else{}   // all cases already covered
}
