* Multi Bean Loader Helper

|

|
|
* This code was originally part of the facade, however it has
|
|
* been decided to remove unique features to service classes like
|
|
* this to make them available to developers not using the facade class.
|
|
*
|
|
* This helper class offers limited support for one-to-one
|
|
* relations by providing a service to load a set of beans
|
|
* with differnt types and a common ID.

/**
|
|
* Loads multiple types of beans with the same ID.
|
|
* This might look like a strange method, however it can be useful
|
|
* for loading a one-to-one relation. In a typical 1-1 relation,
|
|
* you have two records sharing the same primary key.
|
|
* RedBeanPHP has only limited support for 1-1 relations.
|
|
* In general it is recommended to use 1-N for this.
|
|
*
|
|
* Usage:
|
|
*
|
|
* <code>
|
|
* list( $author, $bio ) = R::loadMulti( 'author, bio', $id );
|
|
* </code>
|

*
|
|
* @param OODB $oodb OODB object
|
|
* @param string|array $types the set of types to load at once
|
|
* @param mixed $id the common ID

* @return OODBBean
