Method Summary
	`__init__(self, keyGlobalID, aDatabaseContext, anEditingContext)` Initializes the 'AccessFaultHandler' with the objects it needs to get the data back from the Database.
	`completeInitializationOfObject(self, anObject)` Abstract method implemented by subclasses to populate 'anObject'
	`globalID(self)` Returns the 'KeyGlobalID' of the object this FaultHandler is responsible for.
Inherited from AccessGenericFaultHandler
	`databaseContext(self)` Returns the 'DatabaseContext' object the fault handler uses to fetch data rows from a database.
	`editingContext(self)` Returns the underlying EditingContext --see _setContext().
	`faultWillFire(self, anObject)` Removes itself from the chain of handlers
	`generation(self)` Return the ``generation'' of the fault --see: 'linkAfterHandler()'.
	`linkAfterHandler(self, anAccessGenericFaultHandler, generation)` Adds the FaultHandler to the chain ended by 'anAccessGenericFaultHandler'.
	`next(self)` Returns the successor of 'self' in the chain, or None.
	`previous(self)` Returns the predecessor of 'self' in the chain, or None
	`_handleECDeletion(self, ref)` Automatically called when the EditingContext the FaultHandler (weak-) references is deleted ; simply removes itself from the chain of handlers.
	`_removeSelfFromChain(self)` Removes itself from the chain.
	`_setContext(self, aDatabaseContext, anEditingContext)` Initializes the AccessGenericFaultHandler ; subclasses typically call this method in their '__init__()' method.

Method Details

init(self, keyGlobalID, aDatabaseContext, anEditingContext)
(Constructor)

Initializes the 'AccessFaultHandler' with the objects it needs to get the data back from the Database.

Parameters:

keyGlobalID -- the KeyGlobalID for the faulted object

aDatabaseContext -- the 'DatabaseContext' object responsible for fetching

the data for the object identified by 'keyGlobalID'

anEditingContext -- the 'EditingContext' object managing the graph of

objects in which the object identified by 'keyGlobalID' participates.

completeInitializationOfObject(self, anObject)

Abstract method implemented by subclasses to populate 'anObject'

Parameter:

anObject -- an object implementing the 'Faulting' interface. Within the

framework, it is typically a 'DatabaseObject'

Overrides:: Modeling.FaultHandler.AccessGenericFaultHandler.completeInitializationOfObject (inherited documentation)

globalID(self)

Returns the 'KeyGlobalID' of the object this FaultHandler is responsible for.
