QueryR EntityStore

, _(*1)

Provides persistence and basic lookup capabilities for collections of Wikibase entities., _(*2)

System dependencies

PHP 5.5 or later (PHP 7 and HHVM are supported)
php5-sqlite (only needed for running the tests)

Installation

To add this package as a local, per-project dependency to your project, simply add a dependency on queryr/entity-store to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on EntityStore 1.x:, _(*3)

{
    "require": {
        "queryr/entity-store": "~1.0"
    }
}

Usage

If you are curious what the database schema is, look at src/EntityStoreInstaller.php., _(*4)

All services are constructed via the EntityStoreFactory class:, _(*5)

use Queryr\EntityStore\EntityStoreFactory;
$factory = new EntityStoreFactory(
    $dbalConnection,
    new EntityStoreConfig( /* optional config */ )
);

$dbalConnection is a Connection object from Doctrine DBAL., _(*6)

Writing values

For writing values, you will need either ItemStore or PropertyStore., _(*7)

$itemStore = $factory->newItemStore();
$propertyStore = $factory->newPropertyStore();

The main write methods are "store document" and "remove document by id"., _(*8)

$itemStore->storeItemRow( $itemRow );
$itemStore->deleteItemById( $itemId );

Note that $itemRow is of type ItemRow, which is defined by this component. ItemRow represents all values in a row of the items table. It does not require having a fully instantiated Wikibase DataModel EntityDocument object, you just need the JSON., _(*9)

Next to ItemRow there also is ItemInfo, which is identical, apart for not having the JSON. (Internally these share code via the package private trait ItemRowInfo.), _(*10)

Querying values

This list is incomplete and serves mainly to give you an idea of what this library contains. To get a full list, look at the services you can construct via the store, and their interfaces., _(*11)

Fetching an Item by id, _(*12)

$q42 = $itemStore->getItemRowByNumericItemId( 42 );

Property data type lookup, _(*13)

$lookup = $factory->newPropertyTypeLookup();
$propertyType = $lookup->getTypeOfProperty( $propertyId );

List item info, _(*14)

Get cheaply retrievable info on the first 100 items., _(*15)

$itemInfoList = $itemStore->getItemInfo( 100, 0 );

Restrict the result to items of type "book", assuming 424242 is the numeric id of "book"., _(*16)

$itemInfoList = $itemStore->getItemInfo( 100, 0, 424242 );

List item types, _(*17)

This will get you numeric item ids that represent the types of the items ("instance of") in the system., _(*18)

$itemTypes = $itemStore->getItemTypes();

Running the tests

For tests only, _(*19)

composer test

For style checks only, _(*20)

composer cs

For a full CI run, _(*21)

composer ci
