Public Methods

Method	Description
CanBypassStoreMethod ( ) : System.Boolean	Indicates if updates to objects can bypass the Store method and OnChange notifications for efficiency.
Init ( IClassHelper classHelper, IPropertySet extensionProperties ) : void	Initializes the extension.
OnChange ( IObject obj ) : void	Fired when an object's attributes or geometry is updated.
OnCreate ( IObject obj ) : void	Fired when a new object is created.
OnDelete ( IObject obj ) : void	Fired when an object is deleted.
SetTimestampFields ( String createdField, String modifiedField, String userField ) : void	Changes the member variables and extension properties to store the provided field names as the created, modified and user fields (positions are also refreshed). Empty strings indicate the values should not be saved in a field.
Shutdown ( ) : void	Informs the extension that the class is being disposed of.

Private Methods

Method	Description
GetCurrentUser ( ) : String	Gets the name of the extension's user. For local geodatabases, this is the username as known by the operating system (in a domain\username format). For remote geodatabases, the IDatabaseConnectionInfo interface is utilized.
InitNewExtension ( ) : void	This method should be called the first time the extension is initialized, when the extension properties are null. This will create a new set of properties with the default field names.
RegisterFunction ( Type registerType ) : void
SetFieldIndexes ( ) : void	Finds the positions of the created, modified and user fields, and verifies that the specified field has the correct data type.
UnregisterFunction ( Type registerType ) : void
