PHP 클래스 lithium\data\Source

In addition to utility methods and standardized properties, it defines the implementation tasks for all Lithium classes that work with external data, such as connections to remote resources (connect() and disconnect()), introspecting available data objects (entities() and describe()), and a standard read/write interface (create(), read(), update() and delete()). Subclasses may implement any other non-standard functionality, but the above methods define the requirements for interacting with Model objects, and other classes within lithium\data. 파일 보기 프로젝트 열기: unionofrad/lithium 1 사용 예제들

메소드	설명
__construct ( array $config = [] ) : void	Constructor.
__destruct ( ) : void	Destructor. Ensures the connection is closed, before the object is destroyed.
applyStrategy ( array $options, object $context )	Applying a strategy to a lithium\data\model\Query object
configureClass ( string $class ) : array	A method which can be optionally implemented to configure a model class.
connect ( )	Abstract. Must be defined by child classes.
create ( mixed $query, array $options = [] ) : boolean	Create a record. This is the abstract method that is implemented by specific data sources.
delete ( mixed $query, array $options = [] ) : boolean	Abstract. Must be defined by child classes.
describe ( mixed $entity, array $schema = [], array $meta = [] ) : array	Gets the column schema for a given entity (such as a database table).
disconnect ( )	Abstract. Must be defined by child classes.
enabled ( string $feature = null ) : boolean	With no parameter, checks a specific supported feature.
isConnected ( array $options = [] ) : boolean	Checks the connection status of this data source. If the 'autoConnect' option is set to true and the source connection is not currently active, a connection attempt will be made before returning the result of the connection status.
methods ( ) : array	Returns the list of methods which format values imported from Query objects. Should be overridden in subclasses.
name ( string $name ) : string	Quotes data-source-native identifiers, where applicable.
read ( mixed $query, array $options = [] ) : boolean	Abstract. Must be defined by child classes.
relationFieldName ( $type, $name ) : string	Returns the field name of a relation name (underscore).
relationship ( $class, $type, $name, array $options = [] ) : array	Defines or modifies the default settings of a relationship between two models.
sources ( string $class = null ) : array	Returns a list of objects (sources) that models can bind to, i.e. a list of tables in the case of a database, or REST collections, in the case of a web service.
update ( mixed $query, array $options = [] ) : boolean	Updates a set of records in a concrete data store.
