README

A module that processes atomic information units.

Installation

The installation of this library is made via composer and the autoloading of all classes of this library is made through their autoloader.

• Download composer.phar from their website.
• Then run the following command to install this library as dependency :
• php composer.phar install yii2-module/yii2-information

Basic Usage

This module needs the following components to be set at the configuration level:

• 'db_information' should be a \yii\db\Connection

If you already have a database connection, you may use the following trick :

'db_information' => function() { return \Yii::$app->get('db'); },

where 'db' is the id of your database connection.

This module needs the following parameters to be set at the configuration level:

• (none)

You should also modify the configuration of the yii application with the following changes :

[
	...
	'modules' => [
		...
		'information' => [
			'class' => 'Yii2Module\Yii2Information\InformationModule',
		],
		...
	],
	...
]

Console API

The console API uses the following commands, assuming your working directory is the directory where the yii (console) file is, and that the configuration to this module has been named information.

./yii information/process/delete-for-module --moduleId={{moduleId}}

This method deletes all informations related to the module with the given id in the informations tables.

./yii information/process/module --moduleId={{moduleId}}

This method resolves all the records that are stored in the information tables for the module with the given id.

./yii information/process/data --moduleId={{moduleId}}

This method resolves only the information data that are stored for the module with the given id.

./yii information/process/relation --moduleId={{moduleId}}

This method resolves only the information relation that are stored for the module with the given id.

PHP API

The php API, available in the InformationModule component, is defined as follow :

use PhpExtended\Information\InformationVisitorInterface;
use PhpExtended\Information\LoggerInformationVisitor;
use Psr\Log\LoggerInterface;

getStorageHandler(Module $module, LoggerInterface $logger, boolean $checkBeforeInsert = false) : InformationVisitorInterface

This method gets an information handler to handle all the informations that could be thrown at it. If the $checkBeforeInsert parameter is set to true, then this method will decorate the handler with another handler which checks in the current database if the information exists, and if it exists, it will skip storing it. That handler will not check for accuracy of the information, only its existence. This handler is more useful in a multi threaded environment due to the fact it maximizes parallelization of resolving records.

use PhpExtended\Information\InformationVisitorInterface;
use PhpExtended\Information\LoggerInformationVisitor;
use Psr\Log\LoggerInterface;

getResolverHandler(Module $module, LoggerInterface $logger) : InformationVisitorInterface

This method gets an information handler to handle all the informations that could be thrown at it. It will try to resolve it like all the other process methods below, and if it cannot, it will store the record like the storage handler up there. This handler is more useful in a single threaded environment due to the fact it minimizes the number of queries to the database.

processForModule(Module $module, LoggerInterface $logger = null) : void

This method processes all kinds of information for given module. In this context, processing means resolving individual information context to be able to store all of those informations within a relational database which is tailored to handle them. All informations that couldn't be stored accordingly stay in the informations database.

deleteForModule(Module $module) : void

This method deletes all informations related to the given module in the informations tables.

processInformationData(Module $module, LoggerInterface $logger = null) : void

This method processes all the informations of type data for given module. Such informations are assuming the receiving database holds a path field in order to store the information's primary key or identifier.

processInformationRelation(Module $module, LoggerInterface $logger = null) : void

This method processes all the informations of type relation for given module. Such informations are assuming the receiving database holds a path field in order to store the information's primary key or identifier.
