This PHP design mode album from the blog (jymoz.com), now has no access, this series of articles I have been looking for a long time to find the complete, thanks to the author Jymoz's Hard Pay Oh!

==============================================================================

The Zerg Army has a special evolutionary class, the Dragon, the dragon can become the Air guardian (day crab) or devour (empty). There is also the ability to evolve into a thorn in the mouth.
The three change processes are similar: the change of the original force disappears, producing an egg or cocoon, hatching for a while, the egg disappears, and the new army is produced.
If we were to separate these three evolutions, we would have duplicated code and increased redundancy, so we would try to reduce the extra code.

the problem to be solved: The same few steps are going through, but the details of each step are different.

idea: to be a framework for evolutionary engineering, we just have to control the details.

Sample template mode mode:

<?PHP//evolutionary Framework class, it's an abstract class .    Abstract classEvolution {//Framework method, which implements each step, with final prohibit subclasses from overwriting        Final  Public functionProcess$troop)        {            //generate an egg, parameters for the evolutionary force            $egg=$this->becomeegg ($troop); //wait for eggs to hatch, parameters for eggs            $this->waitegg ($egg); //generate new troops after hatching            return $this->becomenew ($egg); }        //the following three abstract methods are implemented by a specific subclass        Abstract  Public functionBecomeegg ($troop); Abstract  Public functionWaitegg ($egg); Abstract  Public functionBecomenew ($egg); }    //for the sake of simplicity, this is demonstrated by the evolution of the aerial defender (Tian Crab), the treatment of the ground thorn and so on, like//The evolutionary class of Tian crab inherits abstract Evolutionary class    classGuardianevolutionextendsEvolution {//implementation generates an egg         Public functionBecomeegg ($troop)        {            //destroy the Dragon, return the code of an Egg object        }        //waiting for eggs to hatch         Public functionWaitegg ($troop)        {            //Wait a few 10 seconds for the code        }        //generate new troops after hatching         Public functionBecomenew (($troop)        {            //destroy the eggs and return a day crab        }    }    //Create a new day crab, the evolutionary object.    $e 1=Newguardianevolution (); //Let it call the parent class's evolutionary framework function and automate three steps    $e 1->process ($sds);?>

Usage Summary: template mode automates a range of steps while satisfying different details.

Implementation Summary: an abstract class is required to contain the framework function, allowing the specific subclass to inherit it and implement all the steps. When used, the frame function is automatically completed as soon as it is called.
