Interface IRelationship

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

AttributedRelationship, IRelationshipProxy, Relationship, SimpleRelationship

public interface IRelationship

extends java.io.Serializable

Provides access to members that return information about the relationship.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Remarks

The IRelationship interface provides read-only information about a relationship. It is most useful with attributed relationships, since it can form a bridge between the attribute information, which is in row form, and the related objects.

When dealing with relationships you will normally use the IRelationshipClass interface, rather than IRelationship.

The SimpleRelationship object represents a pair of related geodatabase objects or features. There are no attribute values associated with the relationship.

You should not cocreate a simple relationship. Instead use IRelationshipClass::CreateRelationship.

The AttributedRelationship object is a kind of row that represents a pair of related objects or features with extra information about the pairing. The extra information is stored in the row.

You should not co-create an attributed relationship. Instead use IRelationshipClass::CreateRelationship.
