IEntityRelation Methods

The IEntityRelation type exposes the following members.

Methods
  NameDescription
Public methodAddEntityFieldPairTEntityField
Adds a new pair of entity fields of type TEntityField to the relation, including persistence info. Primary Key fields and Foreign Key Fields have to be added in pairs. Used by Adapter template set.
Public methodGetAllFKEntityFieldCoreObjects
Returns in an arraylist all IEntityFieldCore objects for the FK fields in this entityrelation
Public methodGetAllFKFieldPersistenceInfoObjects
Returns in an arraylist all IFieldPersistenceInfo objects for the FK fields in this entityrelation
Public methodGetAllPKEntityFieldCoreObjects
Returns in an arraylist all IEntityFieldCore objects for the PK fields in this entityrelation
Public methodGetAllPKFieldPersistenceInfoObjects
Returns in an arraylist all IFieldPersistenceInfo objects for the PK fields in this entityrelation
Public methodGetFKEntityFieldCore
Gets the IEntityFieldCore information about the FK field at index specified
Public methodGetFKFieldPersistenceInfo
Gets the IFieldPersistenceInfo data for the FK field at index specified.
Public methodGetPKEntityFieldCore
Gets the IEntityFieldCore information about the PK field at index specified
Public methodGetPKFieldPersistenceInfo
Gets the IFieldPersistenceInfo data for the PK field at index specified.
Public methodGetUsedEntityTypeNamesAndAliases
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. Also, if the relation contains derived tables, the fields filed under the alias of the derived table are returned.
(Inherited from IRelation.)
Public methodReadXml
Deserializes the object data on the xml reader into this instance
(Inherited from IRelation.)
Public methodSetAliases
Sets the aliases for the start entity and the end entity formed by the fields stored in this entityrelation. The start entity and end entity are determined based on the type of the relation and the primary key / foreign key fields. Mainly used by RelationCollection.Add().
Public methodSetFKFieldPersistenceInfo
Sets the IFieldPersistenceInfo data for the FK field at index specified.
Public methodSetPKFieldPersistenceInfo
Sets the IFieldPersistenceInfo data for the PK field at index specified.
Public methodToggleArtificialAliasingForTargetPerEntityRelations
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 this relation. 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.
(Inherited from IRelation.)
Public methodWriteXml
Serializes the object as xml to the writer specified.
(Inherited from IRelation.)
