Class Description
EOAccessGenericFaultHandler is an abstract class that helps an EOAccessFault to fire by fetching data using an EODatabaseContext. Don't use EOAcceessGenericFaultHandler 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 linkAfterHandlerUsingGeneration
to link one fault after another. Use next
and previous
to traverse the chain.
Instance Methods
generation
public int generation
()
Returns the the receiver's generation, a number that represents when the fault handler was built.
linkAfterHandlerUsingGeneration
public void linkAfterHandlerUsingGeneration
(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.
next
public EOAccessGenericFaultHandler next
()
Returns the next fault in the chain.
previous
public EOAccessGenericFaultHandler previous
()
Returns the previous fault in the chain.
