Class RelationDefinitionRows
Definition of a relation. This table defines the relations that can exist in the database. Each relation has an active text and a passive text. The table RelationTarget specifies which pairs of tables this relation can connect. Use of the active and passive texts is dependent on which direction the relation is viewed in, e.g., active text = "Owns" and passive text = "Is owned by". Collection of RelationDefinitionRow. Each element of the collection represents one row in the RelationDefinition table.

Syntax
public class RelationDefinitionRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, ISoCollection, INotifyCollectionChanged, IBindingList, IList, ICollection, IEnumerable
Remarks
Row collections can be created in several ways.
- Use the static CreateNew() method to create a new, empty collection. You can then add objects of type RelationDefinitionRow to it, and use methods like Save to operate on the whole collection.
- You can create a (nested) RelationDefinitionRows RelationDefinitionRows.CustomSearch object to obtain a query pre-populated with the correct tableinfo and return fields. This query can be modified with restrictions, etc. Then, use the static GetFromCustomSearch(CustomSearch) method to apply the query to the database and obtain the result as a Rows object, with one item for each table row that matched your query.
- For each non-unique index defined for the table, there is a corresponding GetFromIdx method to make retrieving data via the indexes easy.
