Constructors

new Relation(int parentId, int childId, IRelationType relationType)

Constructor for creating a new Relation object. The necessary parameters are the Id of the parent item as an int, the Id of the child as an int and the relationType as IRelationType.

new Relation(int parentId, int childId, Guid parentObjectType, Guid childObjectType, IRelationType relationType)

A second constructor exists but it should not be used because it is used to reconstruct a relation from the data source.
