Introduction

This component is inspired by the the Java programming language.

FlorianWolters\Component\Core\Cloneable consists of six artifacts:

1. The interface __clone method of a class that it is legal for that method to make a field-for-field copy of instances of that class.
2. The exception class CloneableInterface.
3. The trait __clone method of a class that it is illegal for that method to make a field-for-field copy of instances of that class.
4. The trait __clone method of a class that it is legal for that method to make a shallow field-for-field copy of instances of that class.
5. The trait __clone method of a class that it is legal for that method to make a deep field-for-field copy of instances of that class.
6. The static class FlorianWolters\Component\Core\CloneUtils: Offers operations to clone objects.

Features

• Disallows cloning via the magic method __clone by using the trait CloneNotSupportedException is thrown.
• Allows (type safe) cloning via the magic method __clone by implementing the interface DeepCloneTrait to make a deep copy of an instance of the class.
• Allows creating deep copies of any object via the method copyDeep of the class CloneUtils.
• Artifacts tested with both static and dynamic test procedures:
  • Dynamic component tests (unit and integration tests) implemented with PHPUnit.
  • Static code analysis performed using the following tools:
    • PHP_CodeSniffer: Style Checker
    • PHP Mess Detector (PHPMD): Code Analyzer
    • PHP Depend: Code Metrics
    • phpcpd: Copy/Paste Detector (CPD)
    • phpdcd: Dead Code Detector (DCD)
    • SensioLabs Security Checker: Security Checker
  • Continuous Integration (CI) using the following web services:
    • Scrutinizer CI
    • SensioLabsInsight
    • Coveralls
    • VersionEye
    • Depending
    • Waffle
• Provides a Packagist package which can be installed using the dependency manager Composer. Click here for the package on Packagist.
• Provides a complete Application Programming Interface (API) documentation generated with the documentation generator phpDocumentor. Click here for the API documentation.

• Follows the following "standards" from the PHP Framework Interoperability Group (FIG). PSR stands for PHP Standards Recommendation:

  • PSR-0: Autoloading Standards

    Aims to provide a standard file, class and namespace convention to allow plug-and-play code.

  • PSR-1: Basic Coding Standard

    Aims to ensure a high level of technical interoperability between shared PHP code.

  • PSR-2: Coding Style Guide

    Provides a Coding Style Guide for projects looking to standardize their code.

  • A more modern take on autoloading reflecting advances in the ecosystem.

• Follows the Semantic Versioning (SemVer) specification version 2.0.0.

Usage

The best documentation for FlorianWolters\Component\Core\Cloneable are the unit tests, which are shipped in the package.

Installation

FlorianWolters\Component\Core\Cloneable should be installed using the dependency manager Composer.

Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you.

The Composer installer can be downloaded with php.

php -r "readfile('https://getcomposer.org/installer');" | php

This will just check a few PHP settings and then download composer.phar to your working directory. This file is the Composer binary. It is a PHAR (PHP archive), which is an archive format for PHP which can be run on the command line, amongst other things.

To resolve and download dependencies, run the install command:

php composer.phar install
