Member Function Documentation

static EOKeyGlobalID createGlobalID	(	String	entityName,
		Object[]	values
	)			[static]

static NSMutableArray fetchObjectsWithGlobalIDs	(	EOEditingContext	ec,
		NSArray	globalIDs,
		boolean	refreshesRefetchedObjects
	)			[static]

Fetches an array of objects defined by the globalIDs in a single fetch per entity.

Parameters:

	ec	the editing context to fetch within
	globalIDs	the global ids to fetch
	refreshesRefetchedObjects	whether or not to refresh refetched objects

Returns:

the fetched EO's

static NSMutableArray fetchObjectsWithGlobalIDs	(	EOEditingContext	ec,
		NSArray	globalIDs
	)			[static]

Fetches an array of objects defined by the globalIDs in a single fetch per entity without refreshing refetched objects.

Parameters:

	ec	the editing context to fetch within
	globalIDs	the global ids to fetch

Returns:

the fetched EO's

static EOEnterpriseObject fetchObjectWithGlobalID	(	EOEditingContext	ec,
		EOGlobalID	gid
	)			[static]

Fetches an object defined by gid without refreshing refetched objects.

Parameters:

	ec	the editing context to fetch within
	gid	the global id to fetch

Returns:

the fetched EO

static NSArray fireFaultsForGlobalIDs	(	EOEditingContext	ec,
		NSArray	globalIDs
	)			[static]

Fires all faults in the given global IDs on one batch. This is much more efficient than triggering the individual faults later on. The method should use only 1 fetch for all objects per entity.

Parameters:

	ec
	globalIDs

static NSArray fireFaultsForGlobalIDs	(	EOEditingContext	ec,
		NSArray	globalIDs,
		NSArray	prefetchingKeypaths
	)			[static]

Fires all faults in the given global IDs on one batch together with their relationships. This is much more efficient than triggering the individual faults and relationships later on. The method should use only 1 fetch for all objects per entity and then one for each relationship per entity.

Parameters:

	ec
	globalIDs
	prefetchingKeypaths

static NSDictionary globalIDsGroupedByEntityName

(

NSArray

globalIDs

)

[static]

Groups an array of global IDs by their entity name.

Parameters:

globalIDs

static NSArray<EOGlobalID> globalIDsWithPrimaryKeyValues	(	String	entityName,
		NSArray< Object >	values
	)			[static]

Translates an array of single-value raw primary values to EOGlobalIDs.

Parameters:

	entityName
	values

static NSArray<Object> primaryKeyValuesWithGlobalIDs

(

NSArray< EOGlobalID >

globalIDs

)

[static]

Translates an array of EOGlobalID to primary key values. Returns null if the given global IDs are not EOKeyValueGlobalIDs and the primary keys are not single values.

Parameters:

globalIDs
