PHP Class Horde_Rdo_Mapper, horde

Controls mapping of entity obects (instances of Horde_Rdo_Base) from and to Horde_Db_Adapters. Public properties: $adapter - Horde_Db_Adapter that stores this Mapper's objects. $inflector - The Horde_Support_Inflector this mapper uses to singularize and pluralize PHP class, database table, and database field/key names. $table - The Horde_Db_Adapter_Base_TableDefinition object describing the main table of this entity.

Inheritance: implements Countable

Protected Properties

Property	Type	Description
$_classname	string	What class should this Mapper create for objects? Defaults to the Mapper subclass' name minus "Mapper". So if the Rdo_Mapper subclass is UserMapper, it will default to trying to create User objects.
$_defaultSort	string	Default sorting rule to use for all queries made with this mapper. This is a SQL ORDER BY fragment (without 'ORDER BY').
$_factory	Horde_Rdo_Factory	The caching factory, if used
$_lazyFields	array	Fields that should only be read from the database when they are accessed.
$_lazyRelationships	array	Relationships that should only be read from the database when they are accessed.
$_relationships	array	Relationships for this entity.
$_setTimestamps	boolean	Timestamps are always GMT for portability.
$_tableDefinition	Horde_Db_Adapter_Base_TableDefinition	The definition of the database table (or view, etc.) that holds this Mapper's objects.

Public Methods

Method	Description
__construct ( Horde_Db_Adapter $adapter )
__get ( string $key ) : mixed	Provide read-only, on-demand access to several properties. This method will only be called for properties that aren't already present; once a property is fetched once it is cached and returned directly on any subsequent access.
addRelation ( string $relationship, Horde_Rdo_Base $ours, Horde_Rdo_Base $theirs )	Adds a relation.
count ( mixed $query = null ) : integer	Count objects that match $query.
create ( array $fields ) : Horde_Rdo_Base	Create a new object in the backend with $fields as initial values.
delete ( string \| Horde_Rdo_Base \| Horde_Rdo_Query $object ) : integer	Deletes a record from the backend. $object can be either a primary key, an Rdo_Query object, or an Rdo object.
exists ( mixed $query ) : boolean	Check if at least one object matches $query.
find ( $arg = null )	find() can be called in several ways.
findOne ( $arg = null )	findOne can be called in several ways.
map ( array $fields = [] ) : Horde_Rdo_Base	Create an instance of $this->_classname from a set of data.
mapFields ( Horde_Rdo_Base $object, array $fields = [] )	Update an instance of $this->_classname from a set of data.
mapperToEntity ( ) : string	Transform this mapper's class name to an entity class name.
mapperToTable ( ) : string	Transform this mapper's class name to a database table name.
removeRelation ( string $relationship, Horde_Rdo_Base $ours, Horde_Rdo_Base $theirs = null ) : integer	Removes a relation to one of the relationships defined in the mapper.
setFactory ( Horde_Rdo_Factory $factory = null ) : Horde_Rdo_Mapper	Attach a Horde_Rdo_Factory to the mapper.
sortBy ( string $sort )	Set a default sort rule for all queries done with this Mapper.
tableToMapper ( string $table ) : Horde_Rdo_Mapper	Transform a table name to a mapper class name.
update ( string \| Rdo $object, array $fields = null ) : integer	Updates a record in the backend. $object can be either a primary key or an Rdo object. If $object is an Rdo instance then $fields will be ignored as values will be pulled from the object.

Method Details

$adapter	Horde_Db_Adapter

__get() public method

These properties are available: adapter: The Horde_Db_Adapter this mapper is using to talk to the database. factory: The Horde_Rdo_Factory instance, if present inflector: The Horde_Support_Inflector this Mapper uses to singularize and pluralize PHP class, database table, and database field/key names. table: The database table or view that this Mapper manages. tableDefinition: The Horde_Db_Adapter_Base_TableDefinition object describing the table or view this Mapper manages. fields: Array of all field names that are loaded up front (eager loading) from the table. lazyFields: Array of fields that are only loaded when accessed. relationships: Array of relationships to other Mappers. lazyRelationships: Array of relationships to other Mappers which are only loaded when accessed.

public __get ( string $key ) : mixed
$key	string	Property name to fetch
return	mixed	Value of $key

addRelation() public method

- For one-to-one relations, simply updates the relation field. - For one-to-many relations, updates the related object's relation field. - For many-to-many relations, adds an entry in the "through" table. - Performs a no-op if the peer is already related.

public addRelation ( string $relationship, Horde_Rdo_Base $ours, Horde_Rdo_Base $theirs )
$relationship	string	The relationship key in the mapper.
$ours	Horde_Rdo_Base	The object from this mapper to add the relation.
$theirs	Horde_Rdo_Base	The other object from any mapper to add the relation.

count() public method

Count objects that match $query.

public count ( mixed $query = null ) : integer
$query	mixed	The query to count matches of.
return	integer	All objects matching $query.

create() public method

Create a new object in the backend with $fields as initial values.

public create ( array $fields ) : Horde_Rdo_Base
$fields	array	Array of field names => initial values.
return	Horde_Rdo_Base	The newly created object.

delete() public method

Deletes a record from the backend. $object can be either a primary key, an Rdo_Query object, or an Rdo object.

public delete ( string \| Horde_Rdo_Base \| Horde_Rdo_Query $object ) : integer
$object	string \| Horde_Rdo_Base \| Horde_Rdo_Query	The Rdo object, Horde_Rdo_Query, or unique id to delete.
return	integer	Number of objects deleted.

exists() public method

Check if at least one object matches $query.

public exists ( mixed $query ) : boolean
$query	mixed	Either a primary key, an array of keys => values, or a Horde_Rdo_Query object.
return	boolean	True or false.

find() public method

Primary key mode: pass find() a numerically indexed array of primary keys, and it will return a list of the objects that correspond to those keys. If you pass find() no arguments, all objects of this type will be returned. If you pass find() an associative array, it will be turned into a Horde_Rdo_Query object. If you pass find() a Horde_Rdo_Query, it will return a list of all objects matching that query.

public find ( $arg = null )

findOne() public method

Primary key mode: pass find() a single primary key, and it will return a single object matching that primary key. If you pass findOne() no arguments, the first object of this type will be returned. If you pass findOne() an associative array, it will be turned into a Horde_Rdo_Query object. If you pass findOne() a Horde_Rdo_Query, it will return the first object matching that query.

public findOne ( $arg = null )

map() public method

Create an instance of $this->_classname from a set of data.

Transform this mapper's class name to a database table name.

public mapperToTable ( ) : string
return	string	The database table name.

removeRelation() public method

- For one-to-one and one-to-many relations, simply sets the relation field to 0. - For many-to-many, either deletes all relations to this object or just the relation to a given peer object. - Performs a no-op if the peer is already unrelated. This is a proxy to the mapper's removeRelation method.

public removeRelation ( string $relationship, Horde_Rdo_Base $ours, Horde_Rdo_Base $theirs = null ) : integer
