RelationCollection Properties

The RelationCollection type exposes the following members.

Properties
  NameDescription
Public propertyCapacity
Returns the capacity of the collection
Public propertyCount
returns the number of relations in this collection
Public propertyCustomFilterParameters
Gets Custom Filter Parameters, created in ToQueryText and which are used in custom filters.
Public propertyDatabaseSpecificCreator
Object which will be used to create valid parameter objects, field names, including prefix/postfix characters, and conversion routines, and field names, including prefix/postfix characters. Uses the strategy pattern so the generic code can work with more than one target database.
Public propertyFromClauseDirectives
Gets from clause directives which are to be set on FROM clause elements in the resulting SQL query.
Public propertyItem
Indexer in the collection.
Public propertyObeyWeakRelations
Gets / sets ObeyWeakRelations, which is the flag to signal the collection what kind of join statements to generate in the ToQueryText statement, which is called by the DQE. Weak relationships are relationships which are optional, for example a customer with no orders is possible, because the relationship between customer and order is based on a field in order. When this property is set to true (default: false), weak relationships will result in LEFT JOIN statements. When set to false (which is the default), INNER JOIN statements are used.
Public propertySelectListAlias
Optional alias for select list fields. Used in entity fetches where the entity type to fetch has to be aliased because the source of the data is a derived table or requires aliasing because the relations used require that. If specified, all predicates referring to the entity type to fetch have to use the same alias.
Public propertyWillPotentiallyCauseDuplicateRows
Gets a value indicating whether the contents of this relation collection will result in joins which result in duplicate data. This is the case if there's at least one 1:n or m:n relation.
