FileSystem Repository using nilportugues/repository as foundation.

FileSystem Repository allows you to fetch, paginate and operate with data easily without adding overhead and following good practices.

Table of Contents

Features

  • Repository pattern right from the start.
  • All operations available from the beginning:
    • Search the repository using PHP objects
    • Filtering is available using the Filter object.
    • Fetching certaing fields is available using the Fields Object.
    • Pagination is solved available using the Page and Pageable objects.
  • Want to change persistence layer? Provided repository alternatives are:
  • Caching layer required? Easily to add!
    • Require the Repository Cache package from Composer to add consistent caching to all operations.

Installation

Use Composer to install the package:

$ composer require nilportugues/filesystem-repository

Usage

<?php
use NilPortugues\Foundation\Infrastructure\Model\Repository\FileSystem\Drivers\NativeFileSystem;
use NilPortugues\Foundation\Infrastructure\Model\Repository\FileSystem\FileSystemRepository;

//-------------------------------------------------------------------
// Setting up the repository directory and how it will be access:
//-------------------------------------------------------------------
$baseDir = __DIR__.'/data/colors';
$fileSystem = new NativeFileSystem($baseDir);
$fileRepository = new FileSystemRepository($fileSystem);

//-------------------------------------------------------------------
// Create sample data
//-------------------------------------------------------------------
$red = new Color('Red', 1);
$blue = new Color('Blue', 2)
$fileRepository->addAll([$red, $blue]);

//-------------------------------------------------------------------
// Now let's try filtering by id
//-------------------------------------------------------------------
$filter = new Filter();
$filter->must()->equal('id', 1); //id is a Color property.

print_r($fileRepository->findBy($filter));

//-------------------------------------------------------------------
// Now let's try filtering by contaning 'e' in the name and sort them.
//-------------------------------------------------------------------
$filter = new Filter();
$filter->must()->contain('name', 'e'); //name is a Color property.

$sort = new Sort();
$sort->setOrderFor('name', new Order('DESC'));

print_r($fileRepository->findBy($filter, $sort)); // This will return both values.

//-------------------------------------------------------------------
//Lets remove all colors from the repository
//-------------------------------------------------------------------
$fileRepository->removeAll();

Repository

The repository class implements all the methods required to interact and filter your data.

  • public function add($value)
  • public function addAll(array $values)
  • public function remove(Identity $id)
  • public function removeAll(Filter $filter = null)
  • public function transactional(callable $transaction)
  • public function find(Identity $id, Fields $fields = null)
  • public function findBy(Filter $filter = null, Sort $sort = null, Fields $fields = null)
  • public function findByDistinct(Fields $distinctFields, Filter $filter = null, Sort $sort = null, Fields $fields = null)
  • public function findAll(Pageable $pageable = null)
  • public function count(Filter $filter = null)
  • public function exists(Identity $id)

Data Operations

All data can be extracted by fields name, using filters, applying ordering and pages, capable of applying fields, filters and ordering criteria.

Fields

Selecting by field will make hydratation fail. Currently partial object hydratation is not supported.

Class: NilPortugues\Foundation\Domain\Model\Repository\Fields

Methods:

  • public function __construct(array $fields = [])
  • public function add($field)
  • public function get()

Filtering

Class: NilPortugues\Foundation\Domain\Model\Repository\Filter

Methods:

  • public function filters()
  • public function must()
  • public function mustNot()
  • public function should()
  • public function clear()

For must(), mustNot() and should(), the methods available are:

  • public function notStartsWith($filterName, $value)
  • public function notEndsWith($filterName, $value)
  • public function notEmpty($filterName)
  • public function empty($filterName)
  • public function startsWith($filterName, $value)
  • public function endsWith($filterName, $value)
  • public function equal($filterName, $value)
  • public function notEqual($filterName, $value)
  • public function includeGroup($filterName, array $value)
  • public function notIncludeGroup($filterName, array $value)
  • public function range($filterName, $firstValue, $secondValue)
  • public function notRange($filterName, $firstValue, $secondValue)
  • public function notContain($filterName, $value)
  • public function contain($filterName, $value)
  • public function beGreaterThanOrEqual($filterName, $value)
  • public function beGreaterThan($filterName, $value)
  • public function beLessThanOrEqual($filterName, $value)
  • public function beLessThan($filterName, $value)
  • public function clear()
  • public function get()
  • public function hasEmpty($filterName)

Pagination

Pagination is handled by two objects, Pageable that has the requirements to paginate, and Page that it's actually the page with the page data, such as page number, total number, and the data.

Pageable

Class: NilPortugues\Foundation\Domain\Model\Repository\Pageable

Methods:

  • public function __construct($pageNumber, $pageSize, Sort $sort = null, Filter $filter = null, Fieldse $fields = null)
  • public function offset()
  • public function pageNumber()
  • public function sortings()
  • public function next()
  • public function pageSize()
  • public function previousOrFirst()
  • public function hasPrevious()
  • public function first()
  • public function filters()
  • public function fields()

Page object

Class: NilPortugues\Foundation\Domain\Model\Repository\Page

Methods:

  • public function __construct(array $elements, $totalElements, $pageNumber, $totalPages, Sort $sort = null, Filter $filter = null, Fields $fields = null)
  • public function content()
  • public function hasPrevious()
  • public function isFirst()
  • public function isLast()
  • public function hasNext()
  • public function pageSize()
  • public function pageNumber()
  • public function totalPages()
  • public function nextPageable()
  • public function sortings()
  • public function filters()
  • public function fields()
  • public function previousPageable()
  • public function totalElements()
  • public function map(callable $converter)

Sorting

Class: NilPortugues\Foundation\Domain\Model\Repository\Sort

Methods:

  • public function __construct(array $properties = [], Order $order = null)
  • public function andSort(SortInterface $sort)
  • public function orders()
  • public function equals(SortInterface $sort)
  • public function orderFor($propertyName)
  • public function setOrderFor($propertyName, Order $order)
  • public function property($propertyName)

Ordering

Sometimes you want to sort by multiple fields, this is where Order comes in play.

Class: NilPortugues\Foundation\Domain\Model\Repository\Order

Methods:

  • public function __construct($direction)
  • public function isDescending()
  • public function isAscending()
  • public function __toString()
  • public function equals($object)
  • public function direction()
