Easy ORM for PHP

Meta data

Beans contain meta data. For instance, the type of the bean is stored in the meta data. To obtain the type of a bean:

    $bean->getMeta('type');

You can also store your own meta data in a bean:

    $bean->setMeta'my.secret.property''secret' );

this data will not get stored in the database.

Tainted

Some meta data is accessible using convenience method. For instance if you would like to know whether a bean has been changed since it got retrieved from the database use the tainted() method.

    $bean->isTainted();

Note that a bean is marked as tainted if a list gets accessed.

Old

To determine if a certain property has changed:

    $book R::load'book'$id );
    
$book->hasChanged'title' ); //returns FALSE
    
$book->title 'New title';
    
$book->hasChanged'title' ); //returns TRUE

To get the old value of the property:

    $book->old'title' );

Testing Equality

To test whether two beans have the same type and primary key ID:

    $bean->equals$otherBean );

Empty

To determine if a bean is empty, or only contains empty values (everything that qualifies as empty() in PHP) use:

    $bean->isEmpty();
