PersistentObject::ezcPersistentObjectDefinition

Class ezcPersistentObjectDefinition

Main definition of a persistent object.

Each persistent object will have exactly one definition. The purpose of the definition is to provide information about how the database table is structured and how it is mapped to the data object.

For an elaborate example see ezcPersistentSession.

Properties

string	read/write	`$class` Class-name of the PersistentObject.
array(string=>ezcPersistentObjectProperty)	read/write	`$columns` The fields of the Persistent Object as an array of ezcPersistentObjectProperty. The key is the name of the original database column.
ezcPersistentObjectIdProperty	read/write	`$idProperty` Holds the identifier property.
array(string=>ezcPersistentObjectProperty)	read/write	`$properties` The fields of the Persistent Object as an array of ezcPersistentObjectProperty.
array(string=>ezcPersistentRelation)	read/write	`$relations` Contains the relations of this object. An array indexed by class names of the related object, assigned to a instance of a class derived from ezcPersistentRelation.
string	read/write	`$table` Name of the database table to use.

Member Variables

protected array(string=>mixed)


              $propertyArray
               = array(
        'table'      => null,
        'class'      => null,
        'idProperty' => null,
        'properties' => null,

        'relations'  => null,

Method Summary

public static ezcPersistentObjectDefinition	`__set_state( $array )` Returns a new instance of this class with the data specified by $array.
public ezcPersistentObjectDefinition	`__construct( [ $table = ''] , [ $class = ''] , [ $properties = array()] , [ $relations = array()] , [ $idProperty = null] )` Constructs a new PersistentObjectDefinition.

Methods

__set_state

static ezcPersistentObjectDefinition __set_state( $array )

Returns a new instance of this class with the data specified by $array.

$array contains all the data members of this class in the form: array('member_name'=>value).

__set_state makes this class exportable with var_export. var_export() generates code, that calls this method when it is parsed with PHP.

Parameters:

Name	Type	Description
`$array`	array(string=>mixed)

__construct

ezcPersistentObjectDefinition __construct( [string $table = ''] , [string $class = ''] , [ $properties = array()] , [ $relations = array()] , [ezcPersistentObjectIdProperty $idProperty = null] )

Constructs a new PersistentObjectDefinition.

Parameters:

Name	Type	Description
`$table`	string	The name of the database table to map to.
`$class`	string	The name of the PHP class to map to.
`$properties`	array	The properties of the class. See $properties
`$relations`	array	The relations of the class. See $relations
`$idProperty`	ezcPersistentObjectIdProperty	The primary key of the class/table.
