Interfaces

Interfaces Description

IFeatureProject Provides access to project a feature's geometry.
IObject Provides access to the class the row belongs to.

Remarks

A RelQueryRow represents a row of data in a RelQueryTable. A RelQueryRow can be obtained from a RelQueryCursor (ICursor::NextRow) or methods like ITable::GetRow. The ITable::CreateRow method is not supported and will return an error if used.

The IRow, IRowBuffer and IObject interfaces are always implemented by a RelQueryRow. The IFeature, IFeatureBuffer, and IFeatureDraw interfaces are only implemented if the RelQueryTable has a geometry field.  See the RowBuffer and Row class topics as well as the Object and Feature class topics for more information on rows in general.

A RelQueryRow is read-only, therefore some of the properties and methods in these interfaces may not be supported. The following table lists the unsupported properties and methods. If any of these are used, an error is returned:

Interface Unsupported Property/Method
IRowBuffer Value - Set is unsupported, but Get is supported
IRow Store
Delete
IFeature Shape - Set is unsupported, but Get is supported
IFeatureBuffer Shape - Set is unsupported, but Get is supported
