Create Bridge

Bridge Pattern Generator

Creates Bridge pattern infrastructure for separating abstraction from implementation.

When to Use

Component Characteristics

Abstraction

• High-level interface
• Uses implementor
• Domain layer

RefinedAbstraction

• Extends abstraction
• Adds specialized behavior

Implementor Interface

• Low-level operations
• Multiple implementations

ConcreteImplementor

• Actual implementation
• Platform-specific code

Generation Process

Step 1: Generate Implementor Interface

Path: src/Domain/{BoundedContext}/

1. {Name}ImplementorInterface.php — Low-level operations

Step 2: Generate Abstraction

Path: src/Domain/{BoundedContext}/

1. Abstract{Name}.php — High-level interface

Step 3: Generate RefinedAbstraction

Path: src/Domain/{BoundedContext}/

1. {Type}{Name}.php — Specialized abstractions

Step 4: Generate ConcreteImplementors

Path: src/Infrastructure/{BoundedContext}/

1. {Platform}{Name}Implementor.php — Platform implementations

Step 5: Generate Tests

1. {ClassName}Test.php — Bridge behavior verification

Quick Template Reference

Abstraction

abstract readonly class Abstract{Name}
{
    public function __construct(
        protected {Name}ImplementorInterface $implementor
    ) {}

    abstract public function {operation}({params}): {returnType};
}

RefinedAbstraction

final readonly class {Type}{Name} extends Abstract{Name}
{
    public function {operation}({params}): {returnType}
    {
        {preprocessing}
        return $this->implementor->{implementorMethod}({params});
    }
}

Usage Example

$email = new EmailNotificationImplementor();
$urgent = new UrgentNotification($email);
$urgent->send($message);

// Switch implementation
$sms = new SmsNotificationImplementor();
$urgent = new UrgentNotification($sms);
$urgent->send($message);
