Class Description


The EOCustomObject class provides a default implementation of the EOEnterpriseObject interface. If you need to create a custom enterprise object class, you can subclass EOCustomObject and inherit the Framework's default implementations. Some of the methods are for subclasses to implement or override, but most are meant to be used as defined by EOCustomObject. For information on which methods you should implement in your subclass, see the EOEnterpriseObject interface specification.

EOCustomObject's method implementations are described in the specification for the interface that declares them. For example, you can find a description of how EOCustomObject implements valueForKey (introduced in the EOKeyValueCoding interface) in the specification for EOKeyValueCoding, and you can find a description of how EOCustomObject implements classDescription (introduced in the EOEnterpriseObject interface) in the specification for EOEnterpriseObject.

The only methods provided in EOCustomObject that aren't defined in the EOEnterpriseObject interface are the following three static methods:

You would never invoke these methods, rather, they are provided in EOCustomObject to demonstrate the additional API your custom enterprise objects can implement. Similarly, EOCustomObject's constructors are not meant to be invoked; you would never create an instance of EOCustomObject. Rather, EOCustomObject provides the constructors to demonstrate the constructors your custom enterprise objects should implement.

Constructors



EOCustomObject

public EOCustomObject()

Description forthcoming.

public EOCustomObject( EOEditingContext anEOEditingContext, EOClassDescription anEOClassDescription, EOGlobalID anEOGlobalID)

You would never create an instance of EOCustomObject; rather, your subclasses can create constructors of this same form. A subclass's constructors should create a new object and initialize it with the arguments provided.

See Also: createInstanceWithEditingContext (EOClassDescription)




Static Methods



canAccessFieldsDirectly

public static boolean canAccessFieldsDirectly()

Subclasses implement this method to return false if the key-value coding methods should never access the corresponding instance variable directly on finding no accessor method for a property. You don't have to implement this method if the default behavior of accessing instance variables directly is correct for your objects.

See Also: valueForKey, takeValueForKey



shouldUseStoredAccessors

public static boolean shouldUseStoredAccessors()

Subclasses implement this method to return false if the stored value methods (storedValueForKey and takeStoredValueForKey) should not use private accessor methods in preference to public accessors. Returning false causes the stored value methods to use the same accessor method-instance variable search order as the corresponding basic key-value coding methods (valueForKey and takeValueForKey). You don't have to implement this method if the default stored value search order is correct for your objects.



usesDeferredFaultCreation

public static boolean usesDeferredFaultCreation()

Conformance to EODeferredFaulting.
