RelationCollection Methods

The RelationCollection type exposes the following members.

Methods
  NameDescription
Public methodAdd(IDynamicRelation)
Adds the passed in IDynamicRelation instance to the list
Public methodAdd(IEntityRelation)
Adds the passed in IEntityRelation instance to the list.
Public methodAdd(IRelation)
Adds the passed in relation to this collection
Public methodAdd(IEntityRelation, JoinHint)
Adds the passed in IEntityRelation instance to the list.
Public methodAdd(IEntityRelation, String)
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.
Public methodAdd(IEntityRelation, String, JoinHint)
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.
Public methodAdd(IEntityRelation, String, String, JoinHint)
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.
Public methodAddRange
Adds the range of IRelation objects stored in c to this collection.
Public methodClear
Removes all items from the IList.
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetAllDerivedTables
Gets all derived tables in the relations inside this relation collection.
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
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.
Public methodInsert
Adds the passed in IRelation instance to the list at position index.
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodPreprocessRelations
Preprocesses the relations in this relationcollection The start/end entity can have an inheritance info object with them, causing these relations to be inserted at that spot, where the additional relations for the start entity are added BEFORE the actual relation and the relations for the end entity AFTER the actual relation.
Public methodRemove
Removes the passed in IRelation instance. Only the first instance will be removed.
Public methodToQueryText
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.
Public methodToQueryTextNonAnsi
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.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

Extension Methods
  NameDescription
Public Extension MethodCloneWithoutFirst
Clones the relationcollection without the first relation.
(Defined by ORMClassExtensions.)
Public Extension MethodIsEmpty
Determines whether the specified relation collection is empty. A null passed in is also considered empty.
(Defined by ORMClassExtensions.)
Public Extension MethodLast
Gets the last relation in the passed in relations collection or null if it's empty
(Defined by ORMClassExtensions.)
Public Extension MethodRemoveLast
Removes the last relation from the passed in relationcollection. Assumes last entry is an entity relation
(Defined by ORMClassExtensions.)

Explicit Interface Implementations
  NameDescription
Explicit interface implementationPrivate methodIListAdd
Adds an item to the IList.
Explicit interface implementationPrivate methodIListContains
Determines whether the IList contains a specific value.
Explicit interface implementationPrivate methodICollectionCopyTo
Copies the elements of the ICollection to an Array, starting at a particular Array index.
Explicit interface implementationPrivate methodIEnumerableGetEnumerator
Returns an enumerator that iterates through a collection.
Explicit interface implementationPrivate methodIXmlSerializableGetSchema
This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.
Explicit interface implementationPrivate methodIListIndexOf
Determines the index of a specific item in the IList.
Explicit interface implementationPrivate methodIListInsert
Inserts an item to the IList at the specified index.
Explicit interface implementationPrivate methodIDeserializationCallbackOnDeserialization
Runs when the entire object graph has been deserialized.
Explicit interface implementationPrivate methodIXmlSerializableReadXml
Generates an object from its XML representation.
Explicit interface implementationPrivate methodIListRemove
Removes the first occurrence of a specific object from the IList.
Explicit interface implementationPrivate methodIListRemoveAt
Removes the IList item at the specified index.
Explicit interface implementationPrivate methodIXmlSerializableWriteXml
Converts an object into its XML representation.
Explicit interface implementationPrivate methodIRelationCollectionAddFromClauseDirectives
Adds the from clause directives specified to this collection
Explicit interface implementationPrivate methodIRelationCollectionReadXml
Deserializes the object data on the xml reader into this instance
Explicit interface implementationPrivate methodIRelationCollectionToggleArtificialAliasingForTargetPerEntityRelations
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.
Explicit interface implementationPrivate methodIRelationCollectionWriteXml
Serializes the object as xml to the writer specified.
