IRelationCollection Methods

Adds the passed in IDynamicRelation instance to the list

Adds the passed in IEntityRelation instance to the list.

Adds the passed in relation to this collection

Adds the passed in IEntityRelation instance to the list.

Adds the passed in IEntityRelation instance to the list, under the alias specified for the end entity. The start entity gets no alias. The weakness of the relation is considered based on the ObeyWeakRelations setting.

Adds the passed in IEntityRelation instance to the list, under the alias specified for the end entity and will consider the relation's weakness based on the hint value. The start entity gets no alias.

Adds the passed in IEntityRelation instance to the list, under the aliases specified and will consider the relation's weakness based on the hint value. The start entity gets no alias.

Adds the from clause directives specified to this collection

Adds the range of IRelation objects stored in c to this collection.

Gets all derived tables in the relations inside this relation collection.

Returns an enumerator that iterates through a collection.

Gets per alias specified in a relation all entity names covered by that alias. This means that if an entity in a relation is based on multiple entities (through inheritance) it will return all entity names the entity is based on, from the actual entity to the root of the hierarchy path and every entity name in between.

Adds the passed in IRelation instance to the list at position index.

Deserializes the object data on the xml reader into this instance

Removes the passed in IRelation instance. Only the first instance will be removed.

Enables / disables the artificial aliasing for target per entity relations. This method is used to enable the artificial aliasing of entities which are in a hierarchy of TargetPerEntity and which are in the relations of this collection. This is switched on for dyn/typedlist fetches to be sure dyn/typedlists with fields from multiple entities in the same inheritance hierarchy will be retrievable properly, as they need aliasing under the hood but if the developer didn't alias the entities, the query will fail because the supertype(s) aren't joined multiple types.

Converts the set of relations to a set of nested JOIN query elements using ANSI join syntaxis. Oracle 8i doesn't support ANSI join syntaxis and therefore the OracleDQE has its own join code. It uses a database specific creator object for database specific syntaxis, like the format of the tables / views and fields.

Serializes the object as xml to the writer specified.

Clones the relationcollection without the first relation.

Determines whether the specified relation collection is empty. A null passed in is also considered empty.

Gets the last relation in the passed in relations collection or null if it's empty

Removes the last relation from the passed in relationcollection. Assumes last entry is an entity relation
