Interface IEnumTopologyParent

All Superinterfaces:

Serializable

All Known Implementing Classes:

IEnumTopologyParentProxy

public interface IEnumTopologyParent
extends Serializable

Provides access to the set of parents of a topology element.

Remarks

Unlike most enumerators in the Geodatabase API, the Next method of this interface does not return objects, but esriTopologyParent structs. Since structs are a value types, checking whether a return value is null should not be used as a conditional statement to iterate through the enumerator's values (it will never be null). However, this interface provides a Count property, which can be used to iterate through the values a specific number of times, instead of checking for a terminating condition such as a null value.
