public interface IRowEvents
extends EventListener, Serializable

Provides access to events that occur when an object is modified, created or deleted.

Remarks

The IRowEvents interface allows implementers of custom row objects to take special action in response to changes made to the state of a row object. The geodatabase calls the methods in the IRowEvents interface as changes are made to the state of a row object (see the description of the IRow::Store and IRow::Delete methods).

The OnChanged method is called by the geodatabase when an application program calls Store on an existing Row object.

The OnNew method is called by the geodatabase when an application program calls Store on a newly created Row object.

The OnDelete method is called by the geodatabase when an application program calls Delete on a Row object.

The OnInitialize method is called by the geodatabase after hydrating a cocreated Row object with its state (its set of field values) but before handing the Row to an application program. This is an opportunity for the Row object to initialize further state and derived member variables.

The OnValidate method is unused (deprecated).

Method Summary

void	onChanged(IRowEventsOnChangedEvent theEvent) An after event that is fired when a custom object is changed.
void	onDelete(IRowEventsOnDeleteEvent theEvent) An after event that is fired when a custom object is deleted.
void	onInitialize(IRowEventsOnInitializeEvent theEvent) An after event that is fired when a custom object is initialized.
void	onNew(IRowEventsOnNewEvent theEvent) An after event that is fired when a custom object is Stored for the first time.
void	onValidate(IRowEventsOnValidateEvent theEvent) An after event that is fired when a custom object is validated.

Method Detail

onChanged

void onChanged(IRowEventsOnChangedEvent theEvent)
               throws IOException,
                      AutomationException

An after event that is fired when a custom object is changed.

Remarks

The OnChanged method is called by the geodatabase when an application program calls Store on an existing Row object.

Supported Platforms

Windows, Solaris, Linux

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

onDelete

void onDelete(IRowEventsOnDeleteEvent theEvent)
              throws IOException,
                     AutomationException

An after event that is fired when a custom object is deleted.

Remarks

The OnDelete method is called by the geodatabase when an application program calls Delete on a Row object.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Parameters:

theEvent - The event

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

onInitialize

void onInitialize(IRowEventsOnInitializeEvent theEvent)
                  throws IOException,
                         AutomationException

An after event that is fired when a custom object is initialized.

Remarks

The OnInitialize method is called by the geodatabase after hydrating a cocreated Row object with its state (its set of field values) but before handing the Row to an application program. This is an opportunity for the Row object to initialize further state and derived member variables.

                  AutomationException

An after event that is fired when a custom object is Stored for the first time.

Remarks

The OnNew method is called by the geodatabase when an application program calls Store on a newly created Row object.
