EOAccessGenericFaultHandler

Inherits from: EOFaultHandler (EOControl) : NSObject

Package: com.apple.yellow.eoaccess

Class Description

EOAccessGenericFaultHandler is an abstract class that helps an EOAccessFault to fire by fetching data using an EODatabaseContext. Don't use EOAccessGenericFaultHandler directly; instead, use its subclasses EOAccessFaultHandler and EOAccessArrayFaultHandler.

EOAccessGenericFaultHandler lets you chain together all the fault handlers in the access layer, so the batch faulting mechanism can find other faults related to the one that triggered the batch. Use linkAfterHandler to link one fault after another. Use next and previous to traverse the chain.

Instance Methods

generation

public int generation()

Returns the receiver's generation, a number that represents when the fault handler was built.

linkAfterHandler

public void linkAfterHandler( EOAccessGenericFaultHandler faultHandler, int generation)

Adds the receiver to a chain of fault handlers, after faultHandler. generation is a number that represents when the handler was built. All faults in an access layer can be chained together, so the batch faulting mechanism can find other faults related to the one that triggered the batch.

See Also: next, previous

public EOAccessGenericFaultHandler next()

Returns the next fault in the chain.

public EOAccessGenericFaultHandler previous()

Returns the previous fault in the chain.
