PHP Класс izzum\statemachine\persistence\Redis

Since redis has no schemas (as a nosql db), it should store data based on the way you want to retrieve data. There will be multiple views on the data which should make sense for a lot of use cases (counters, sets, sorted sets, lists, hashes etc) to retrieve the data. All keys that izzum uses in redis can be found in this classes' constants with a 'KEY_' prefix. This class uses the php redis module and your php build should be setup with this module loaded. An instance uses a redis key prefix of 'izzum:' by default. but this can be set to whatever you like. . You can even set the prefix key to something else temporarily for loading the configuration data and then set it to another prefix for writing state data. This allows you to store multiple machine configurations under different prefixes so you can load different machines from different places, which facilitates multiple dev teams working on configuration of different machines without them overwriting other teams' definitions. The configuration of statemachines is a JSON string. The specification of the JSON string can be found in izzum\statemachine\loader\JSON::getJSONSchema. see asset/json/json.schema Internally, this class uses the JSON loader to load the configuration. It can be set up to store multiple configurations under multiple keys. You can use the normal redis connection settings to connect to redis. Показать файл Открыть проект Примеры использования класса

Открытые методы

Метод	Описание
__call ( string $name, mixed $arguments ) : mixed	very very dumb proxy to redis connection. should only be used for testing.
__construct ( string $host = '127.0.0.1', integer $port = 6379, float $timeout, string $reserved = null, integer $retry = null )	The constructor accepts default connection parameters.
__destruct ( )	do some cleanup
__toString ( )
addHistory ( Identifier $identifier, $state, $message = null, $is_exception = false )	{@inheritDoc}
getConfigurationKey ( ) : string	get the configuration key used for storing a json string of machine configurations.
getEntityIds ( $machine, $state = null )	{@inheritDoc}
getPrefix ( ) : string	get the prefix for all keys used
getRedis ( ) : Redis	Gets a lazy loaded \Redis instance that is connected and optionally authenticated.
insertState ( Identifier $identifier, $state, $message = null )	{@inheritDoc}
isPersisted ( Identifier $identifier )	{@inheritDoc}
load ( StateMachine $statemachine )	{@inheritDoc} Load the statemachine with data from a JSON string.
processGetState ( Identifier $identifier )	{@inheritDoc}
setConfigurationKey ( string $key )	set the configuration key to be used for storing a json string of machine configurations.
setConnection ( Redis $redis )	set the redis connection explicitely, useful if you want to share the redis instance when it is created outside this class.
setDatabase ( integer $database )	set the redis database. in case there is an active connection, it switches the database.
setPassword ( string $password )	set password to authenticate to the redis server
setPrefix ( string $prefix )	set the key prefix to be used for all redis keys
setUnixDomainSocket ( $socket )
toString ( )
updateState ( Identifier $identifier, $state, $message = null )	{@inheritDoc}
