Traits

PHP Traits are handy and useful.

Imagining you want to get the term ID by term name from a vocabulary. If there is a trait called TermTraits which has a method called getTermIdByName($vid, $term_name). Your code would be cleaner and simpler.

traits TermTraits {
  public function getTermIdByName($vid, $term_name) {
    // ...
    retrun $tid;
  }
}

class YourClassName {
  use TermTraits;

  public function yourMethod() {
    // ...
    $tid = this-> getTermIdByName($vid, $term_name);
  }
}

Traits are only able to be used in classes and other traits. it's unable to be used in procedural code, such as hook implementations. However, it's still possible to copy and paste code from traits if necessary.

So this module aims to

• Direct use: provide neat traits to developers
• Indirect use: as a trait injects to the well-known Examples for Developers module -- being examples or code snippets to developers
