Method Detail

isEmpty

boolean isEmpty()
                throws IOException,
                       AutomationException
Indicates if the TIN contains no data.

Remarks

IsEmpty is TRUE if the TIN contains no user data. In this state the TIN only has the four dummy nodes and two NODATA triangles added automatically by the software at the time the TIN was created.

IsEmpty is FALSE if any user data has been added to the TIN.

getFields

IFields getFields()

The collection of attribute items of the TIN.

Description

Returns fields used to represent intrinsic attributes of the TIN.

While a TIN doesn't have attributes stored in a database table it does have intrinsic properties that can be treated like attributes. In this manner, TINs can 'pretend' to be like other data types that have attributes. An identify operation is an example where this behavior is useful. An identify tool asks the dataset what attributes (fields) it has and what the values are for a selected feature. For TINs it's based on selected location.

Fields are Elevation, Slope, Aspect, Node Tag Value, and Face Tag Value.
