Subtypes are records in a table or feature class that have been grouped based on an attribute field. Subtypes are implemented by creating coded values and, therefore, are associated with fields of the data type short or long integer. These integer values each represent a feature in the subtype. For example, the following codes in a subtype named WaterMains could represent valid classes in a feature class for water mains:
1—Transmission water mains
2—Distribution water mains
Each subtype can also have its own attribute domain for a given field. Use FieldDomainInfos properties to retrieve a list of fields that have domains assigned to.
