Using Custom Loader Classes

You can provide any of the following static methods in your custom xPDOObject derivative classes to override their behavior, including in driver-specific classes:

• _loadRows
• _loadInstance
• _loadCollectionInstance
• load
• loadCollection
• loadCollectionGraph

This is done with the help of the xPDO::call() method.

Overriding these methods allows you to implement additional behavior or completely change the behavior of loading your table objects via the object and collection methods provided by xPDO and xPDOObject. For instance, it can be used to perform security checks or to add i18n processing before allowing a row to be loaded.

In xPDO 3.x, the xPDO::call() method is used to invoke these static methods on the appropriate class. You can override the behavior by defining these methods in your model classes.
