پیاده سازی کلاس با روش interface, abstract و final (قسمت پانزدهم)

به شکل زیر توجه کنید.این تصویر دارای اشکال مختلفی است که هرکدام دارای فرمول خاص خود در محاسبه مساحت و محیط هستند.
این تفاوت فرمول باعث می شود که در هر شکل متد خود را با توجه به فرمول آن بارنویسی و طراحی کنیم.
اما دو خصوصیت بین همه آنها مشترک است و آن نام شکل و رنگ شکل است.
این تصویر گویای حالت polymorphism است.

برای شروع و تعریف خصوصیات نام شکل و رنگ از کلاس abstract به نام Shape استفاده می کنیم.همچنین متدی به نام getInfo ایجاد می کنیم که وظیفه آن بازگشت اطلاعات شکل است.

مثال:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo()
{
return "name of shape is:".$this->name." and color is:".$this->color;
}
}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo()

{

return "name of shape is:".$this->name." and color is:".$this->color;

}

برای فرمول ها نیز متد مشترک getEnviroment و getAre را بدون بدنه در داخل کلاس CallMethods بصورت interface تعریف می کنیم و در کلاس های مخصوص که ارث بری می کنند آنها را بازنویسی می کنیم.

مثال:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo(){
return "name of shape is:".$this->name." and color is:".$this->color;
}
}

interface CallMethods{
public function getEnviroment();
public function getAre();
}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo(){

return "name of shape is:".$this->name." and color is:".$this->color;

}

interface CallMethods{

public function getEnviroment();

public function getAre();

}

حال برای هر شکل کلاس خود را ایجاد و از کلاس abstract و interface ارث بری می کنیم.
کلاس مربوط به مستطیل:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo(){
return "name of shape is:".$this->name." and color is:".$this->color;
}
}

interface CallMethods{
public function getEnviroment();
public function getAre();
}

class Rectangle extends Shape implements CallMethods{

}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo(){

return "name of shape is:".$this->name." and color is:".$this->color;

}

interface CallMethods{

public function getEnviroment();

public function getAre();

}

class Rectangle extends Shape implements CallMethods{

}

حال هر شکل دارای خصوصیات مخصوص خود است برای مثال مستطیل دارای طول و عرض است پس در کلاس خودش این خصوصیات را تعریف می کنیم.

مثال:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo(){
return "name of shape is:".$this->name." and color is:".$this->color;
}
}

interface CallMethods{
public function getEnviroment();
public function getAre();
}

class Rectangle extends Shape implements CallMethods{
public $length = 0;
public $width = 0;

}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo(){

return "name of shape is:".$this->name." and color is:".$this->color;

}

interface CallMethods{

public function getEnviroment();

public function getAre();

}

class Rectangle extends Shape implements CallMethods{

public $length = 0;

public $width = 0;

}

حال تابع سازنده را در شکل ایجاد می کنیم.این تابع سازنده تنظیم کننده طول و عرض و رنگ و نام شکل است.

مثال:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo(){
return "name of shape is:".$this->name." and color is:".$this->color;
}
}

interface CallMethods{
public function getEnviroment();
public function getAre();
}

class Rectangle extends Shape implements CallMethods{
public $length = 0;
public $width = 0;
public function __construct($l = 0,$w = 0,$c = ""){
$this->length = $l;
$this->width = $w;
$this->color = $c;
$this->name = "rectangle";
}
}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo(){

return "name of shape is:".$this->name." and color is:".$this->color;

}

interface CallMethods{

public function getEnviroment();

public function getAre();

}

class Rectangle extends Shape implements CallMethods{

public $length = 0;

public $width = 0;

public function __construct($l = 0,$w = 0,$c = ""){

$this->length = $l;

$this->width = $w;

$this->color = $c;

$this->name = "rectangle";

}

حال متدهای محاسبه مساحت و محیط را درون کلاس مستطیل بازنویسی می کنیم.

مثال:

<?php
abstract class Shape{
public $name;
public $color;
public function getInfo(){
return "name of shape is:".$this->name." and color is:".$this->color;
}
}

interface CallMethods{
public function getEnviroment();
public function getAre();
}

class Rectangle extends Shape implements CallMethods{
public $length = 0;
public $width = 0;
public function __construct($l = 0,$w = 0,$c = ""){
$this->length = $l;
$this->width = $w;
$this->color = $c;
$this->name = "rectangle";
}

public function getAre()
{
return $this->width * $this->length;
}

public function getEnviroment()
{
return ($this->width + $this->length)*2;
}
}
?>

<?php

abstract class Shape{

public $name;

public $color;

public function getInfo(){

return "name of shape is:".$this->name." and color is:".$this->color;

}

interface CallMethods{

public function getEnviroment();

public function getAre();

}

class Rectangle extends Shape implements CallMethods{

public $length = 0;

public $width = 0;

public function __construct($l = 0,$w = 0,$c = ""){

$this->length = $l;

$this->width = $w;

$this->color = $c;

$this->name = "rectangle";

}

public function getAre()

{

return $this->width * $this->length;

}

public function getEnviroment()

{

return ($this->width + $this->length)*2;

}

طراحی کلاس دایره:

<?php
class Cricle extends Shape implements CallMethods{
public $raduis = 0;
public function __construct($r = 0,$c = ""){
$this->raduis = $r;
$this->color = $c;
$this->name = "Cricle";
}

public function getAre()
{
return pi() * pow($this->raduis,2);
}

public function getEnviroment()
{
return pi() * ($this->raduis * 2);
}
}
?>

<?php

class Cricle extends Shape implements CallMethods{

public $raduis = 0;

public function __construct($r = 0,$c = ""){

$this->raduis = $r;

$this->color = $c;

$this->name = "Cricle";

}

public function getAre()

{

return pi() * pow($this->raduis,2);

}

public function getEnviroment()

{

return pi() * ($this->raduis * 2);

}

طراحی کلاس مربع:

<?php
class Square extends Shape implements CallMethods{
public $border = 0;
public function __construct($b = 0,$c = ""){
$this->border = $b;
$this->color = $c;
$this->name = "Square";
}

public function getAre()
{
return pow($this->border , 2);
}

public function getEnviroment()
{
return $this->border * 4;
}
}
?>

<?php

class Square extends Shape implements CallMethods{

public $border = 0;

public function __construct($b = 0,$c = ""){

$this->border = $b;

$this->color = $c;

$this->name = "Square";

}

public function getAre()

{

return pow($this->border , 2);

}

public function getEnviroment()

{

return $this->border * 4;

}

طراحی کلاس مثلث:

<?php
class Triangle extends Shape implements CallMethods{
public $border = 0;
public $base = 0;
public $height = 0;

public function __construct($b = 0,$g = 0,$h = 0,$c = ""){
$this->border = $b;
$this->base = $g;
$this->height = $h;
$this->color = $c;
$this->name = "Triangle";
}

public function getAre()
{
return ($this->base * $this->height) / 2;
}

public function getEnviroment()
{
return ($this->border * 3);
}
}
?>

<?php

class Triangle extends Shape implements CallMethods{

public $border = 0;

public $base = 0;

public $height = 0;

public function __construct($b = 0,$g = 0,$h = 0,$c = ""){

$this->border = $b;

$this->base = $g;

$this->height = $h;

$this->color = $c;

$this->name = "Triangle";

}

public function getAre()

{

return ($this->base * $this->height) / 2;

}

public function getEnviroment()

{

return ($this->border * 3);

}

استفاده از کلاس های ساخته شده و ساخت شی

در اینجا پس از ساخت کلاس های اشکال مختلف تصمیم به ساخت شی برای هریک می کنیم.

ساخت شی مستطیل:

<?php
$rectangle = new Rectangle(15,8,"red");
echo "Area: ".$rectangle->getArea()."<br>";
echo "Enviroment: ".$rectangle->getEnviroment()."<br>";;
echo $rectangle->getInfo();
?>
/*
Area: 120
Enviroment: 46
name of shape is:rectangle and color is:red
*/

<?php

$rectangle = new Rectangle(15,8,"red");

echo "Area: ".$rectangle->getArea()." ";

echo "Enviroment: ".$rectangle->getEnviroment()." ";;

echo $rectangle->getInfo();

Area: 120

Enviroment: 46

name of shape is:rectangle and color is:red

ساخت شی دایره:

<?php
$cricle = new Cricle(15,"green");
echo "Area: ".$cricle->getArea()."<br>";
echo "Enviroment: ".$cricle->getEnviroment()."<br>";;
echo $cricle->getInfo()."<br><br>";
?>
/*
Area: 706.8583470577
Enviroment: 94.247779607694
name of shape is:Cricle and color is:green
*/

<?php

$cricle = new Cricle(15,"green");

echo "Area: ".$cricle->getArea()." ";

echo "Enviroment: ".$cricle->getEnviroment()." ";;

echo $cricle->getInfo()." ";

Area: 706.8583470577

Enviroment: 94.247779607694

name of shape is:Cricle and color is:green

ساخت شی مربع:

<?php
$square = new Square(10,"yellow");
echo "Area: ".$square->getArea()."<br>";
echo "Enviroment: ".$square->getEnviroment()."<br>";;
echo $square->getInfo()."<br><br>";
?>
/*
Area: 100
Enviroment: 40
name of shape is:Square and color is:yellow
*/

<?php

$square = new Square(10,"yellow");

echo "Area: ".$square->getArea()." ";

echo "Enviroment: ".$square->getEnviroment()." ";;

echo $square->getInfo()." ";

Area: 100

Enviroment: 40

name of shape is:Square and color is:yellow

ساخت شی مثلث:

<?php
$triangle = new Triangle(3, 10,5, "red");
echo "Area: ".$triangle->getArea()."<br>";
echo "Enviroment: ".$triangle->getEnviroment()."<br>";;
echo $triangle->getInfo()."<br><br>";
?>
/*
Area: 25
Enviroment: 9
name of shape is:Triangle and color is:red
*/

<?php

$triangle = new Triangle(3, 10,5, "red");

echo "Area: ".$triangle->getArea()." ";

echo "Enviroment: ".$triangle->getEnviroment()." ";;

echo $triangle->getInfo()." ";

Area: 25

Enviroment: 9

name of shape is:Triangle and color is:red
