adobe bridge php design pattern Bridge bridge mode

复制代码 代码如下:

/**
* Bridge mode
*
* Separate the abstract part from its implementation part, and use them to make independent changes
*/
abstract class Implementor
{
abstract public function operation();
}
class ConcreteImplementorA extends Implementor
{
public function operation()
{
echo "ConcreteImplementorA Operation
";
}
}
class ConcreteImplementorB extends Implementor
{
public function operation()
{
echo "ConcreteImplementorB Operation
";
}
}
class Abstraction
{
protected $_implementor = null;
public function setImplementor($implementor)
{
$this->_implementor = $implementor;
}
public function operation()
{
$this->_implementor->operation();
}
}
class RefinedAbstraction extends Abstraction
{
}
class ExampleAbstraction extends Abstraction
{
}
//
$objRAbstraction = new RefinedAbstraction();
$objRAbstraction->setImplementor(new ConcreteImplementorB());
$objRAbstraction->operation();
$objRAbstraction->setImplementor(new ConcreteImplementorA());
$objRAbstraction->operation();
$objEAbstraction = new ExampleAbstraction();
$objEAbstraction->setImplementor(new ConcreteImplementorB());
$objEAbstraction->operation();
