Detailed Description

Provides a cache for to-many faults. Useful when you have a lot (say a few thousand) objects for which you need to access a to-many relationship that hasn't been fetched yet.

The idea is that instead of batch-faulting you could fetch all the entries for a given to-many relationship in one fetch (as raw rows), group them in memory and register the faults here. Then you set up your EODatabaseContext delegate to use this object to try and clear the fault first.

Member Function Documentation

boolean clearFault

(

Object

obj

)

Attempts to clear a fault by looking up the source global id and faulting in the corresponding destination values.

Parameters:

obj

Returns:

true if the fault could be cleared or it wasn't a fault in the first place, false if not

void registerRelationshipCacheEntries	(	String	entityName,
		String	relationshipName,
		NSDictionary	entries
	)

Register the to-many faults by entity name and relationship name. The entries are a dictionary where the key is the source EOGlobalID for the relationship and the values are arrays of global IDs for the destination.

Parameters:

	entityName
	relationshipName
	entries

NSDictionary relationshipCacheEntriesForEntity	(	String	entityName,
		String	relationshipName
	)			[private]
