Metrics overview

Unique Sets

API ID: CountSetsUnique
Languages: Any
Targets: Objects

The number of unique entities that set this object

Example:

    int a_global = 0;      // + 1 set reference (by file)
    void function1() {
      a_global += 1;
      if (a_global > 1)
        a_global = 0;      // + 1 set reference (by function1)
    }
    void function2() {
      a_global -= 1;
      a_global -= 1;
      if (a_global < 0)
        a_global = 0;      // + 1 set reference (by function2)
      if (a_global > 10)
        a_global = 10;     //     duplicate reference does not count
    }
                           // CountSetsUnique = 3
