Metrics overview

Maximum Call Depth

API ID: MaxCallDepth
Languages: Any
Targets: Functions

The maximum depth of the call tree or -1 for recursive

Also known as Hersteller Initiative Software (HIS) LEVEL metric.

Example:

    void depth0() {}            // MaxCallDepth = 0
    void depth1() { depth0(); } // MaxCallDepth = 1
    void depth2() { depth1(); } // MaxCallDepth = 2

    void depth2b()              // MaxCallDepth = 2
    {
      depth0();
      depth1();
    }

    void recursive()            // MaxCallDepth = -1 recursion
    {
      recursive();
    }

    void a();
    void b() { a(); }           // MaxCallDepth = -1 recursion
    void c() { b(); }           // MaxCallDepth = -1 recursion
    void a() { c(); }           // MaxCallDepth = -1 recursion

    void callsCycle() { a(); }  // MaxCallDepth = -1 recursion
