IRelationCollection Properties

Returns the amount of relations in this object

Gets Custom Filter Parameters, created in ToQueryText and which are used in custom filters.

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.

Gets from clause directives which are to be set on FROM clause elements in the resulting SQL query.

Indexer in the collection. Returned value can be IEntityRelation or IDynamicRelation

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.

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.

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.
