Class Description

EOKeyGlobalID is a concrete subclass of EOGlobalID whose instances represent persistent IDs based on EOModel information: an entity and the primary key values for the object being identified. When creating an EOKeyGlobalID, the key values must be supplied following alphabetical order for their attribute names. EOKeyGlobalID defines the globalIDWithEntityName for creating instances, but it's much more convenient to create instances from fetched rows using EOEntity's globalIDForRow method. (EOEntity and EOModel are defined in EOAccess.) Note that you don't use a constructor to create EOKeyGlobalIDs.

Static Methods

globalIDWithEntityName

public static EOKeyGlobalID globalIDWithEntityName( String entityName, NSArray keyValues)

Returns an EOKeyGlobalID based on entityName and keyValues.

EOKeyGlobalIDs are more conveniently created using EOEntity's globalIDForRow method (EOAccess).

Instance Methods

entityName

public String entityName()

Returns the name of the entity governing the object identified by the receiver. This is used by EODatabaseContexts (EOAccess) to identify an EOEntity (EOAccess) in methods such as faultForGlobalID.

equals

public boolean equals(Object anObject)

Returns true if the receiver and anObject share the same entity name and key values, false if they don't.
