Properties
  NameDescription
Public propertyActiveContext
Gets / sets the active context this entity is in. Setting this property is adding the entity to the context, and it will make contained entities be added to the passed in context as well. If the entity is already in a context, setting this property has no effect. Setting this property is done by framework code, use the Context's Add/Get methods to work with contexts and entities.
Public propertyAuditorToUse
Gets or sets the Auditor for this entity.
Public propertyAuthorizerToUse
Gets or sets the Authorizer for this entity.
Public propertyConcurrencyPredicateFactoryToUse
Gets / sets the IConcurrencyPredicateFactory to use for GetConcurrencyPredicate(ConcurrencyPredicateType).

Methods
  NameDescription
Protected methodAddInternalsToContext

Protected methodCreateAuthorizer
Creates the authorizer object for this entity. Routine is called when the entity is constructed. Implement in an entity class to set a particular entity authorizer object at construction time. Use this method if you don't want to use LLBLGen Pro's build in dependency injection mechanism.
Protected methodCreateConcurrencyPredicateFactory
Creates the concurrency predicate factory for this entity. Routine is called from the entity constructor. Implement in an entity class to set a particular ConcurrentyPredicateFactory object at construction time. Use this method if you don't want to use LLBLGen Pro's build in dependency injection mechanism.
Protected methodCreateEntityFactoryCore
Creates a new entity factory instance related to this entity.
Protected methodCreateFields

Public methodDiscardSavedFields
Removes all saved field sets from the internal hashtable, clearing up space. This method is also called when an entity is saved.
Protected methodEntity2Xml
Produces the actual XML for this entity, recursively. Because it recurses through referenced entities, it keeps track of which objects are processed so cyclic references are not resulting in cyclic recursion and thus a crash.
Public methodEquals
Compares passed in object with the given object. This is a compare of PK fields. These have to be the same in VALUES. When the values are not the same, or the type is not the same as the current type, false is returned, true otherwise. When this doesn't have any PK fields, all fields are compared. null values are considered as the same value.
(Overrides ObjectEquals(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.)
Protected methodFixupDeserialization(IFieldInfoProvider)

(Overrides ObjectGetHashCode.)
Protected methodGetInheritanceInfoProvider
Gets the inheritance info provider instance of the project this entity instance is located in.

Not called if a fieldvalue set action failed. This method is called before changed events are raised.
Protected methodOnGetFetchNewAuthorizationFailureResultHint
Returns the FetchNewAuthorizationFailureResultHint as returned by the authorizer. Only called when the CanGetLoad failed (authorization failed, so load was denied)

This method is only called when standard checks already succeeded, so value isn't null, and value does match the destination column definition of the EntityField related to fieldIndex.
Protected methodPerformCustomXmlDeserialization
Performs custom XML deserialization for properties which have the CustomXmlSerializationAttribute. The xmlreader should be used to read the xml from. The reader is positioned on the StartElement of the property which has the name of the property. Check if the element is empty and if not, read till the reader is positioned on the EndElement of the property (which also has the same name). Your override has to set the property's value, using the descriptor's SetValue method.
Protected methodPerformCustomXmlSerialization
Performs custom XML serialization for properties which have the CustomXmlSerializationAttribute. Override this method if for some property the data has to be serialized into the output. The xmlwriter should be used to write xml to. You shouldn't emit a startelement with the propertyname, that's already done. Also you shouldn't emit an endelement with the propertyname, that will be done for you. Simply emit XML with the data. Be sure the xml data is valid. You can use the XmlHelper class if necessary.

Events
  NameDescription
Public eventAfterSave
Event handler declaration for the event that is fired each time this entity is persisted. Related entities can subscribe to this event to start housekeeping actions, like syncing internal FK fields with the PK fields of this entity.
Public eventEntityContentsChanged
Event handler declaration for the event that is fired each time the one of values of this entity are changed. The event does not contain the value / field which is changed, it only signals subscribers the entity is changed and the subscriber should act accordingly, f.e. fire a ListChanged event.
Public eventInitialized
Event which is raised at the end of the initialization method of the entity. This event is also raised if the entity is pre-filled with a filled EntityFields(2) object. In your handler, check the State property of the entity Fields to see if you're dealing with a new entity or with an entity which is new, but pre-initialized with filled field objects.
Public eventInitializing
Event which is raised at the start of the initialization method of the entity. The entity is clean and has no entity fields object yet.
Public eventPropertyChanged
Event fired when a field / property is changed. To fire this event from a derived class, call OnPropertyChanged.
Top
Fields
  NameDescription
Public fieldStatic memberAllowReadsFromDeletedEntities
Flag (default: false) which controls whether reading from an entity object which has been deleted (its Fields.State is EntityState.Deleted) results in an ORMEntityIsDeletedException (false) or not (true).
Public fieldStatic memberBuildInValidationBypassMode
The mode (default: NoBypass) to use for the build-in validation checks. Build-in validation checks are performed on every value a field is set to, unless this mode is set to a different value than NoBypass which makes the code to bypass these build-in validation checks. The build-in validation checks are used to prevent overflow exceptions when the entity is persisted to the database.
Public fieldStatic memberMakeInvalidFieldReadsFatal
Flag (default: false), which can be used to track down errors in code at runtime when migrating from LLBLGen Pro v1.0.xx to v2.0. When set to true, it will make invalid field reads fatal and will make the entity throw an ORMInvalidFieldReadException when a field is read while the field's value hasn't been set yet.
Public fieldStatic memberMakeSettingNonNullableFieldsToNullFatal
Flag (default: false) which directs the built-in validation logic to throw an ArgumentOutOfRangeException exception when a field which is non-nullable is set to null / nothing. When false, the set action is silently ignored if a non-nullable field is set to null and results in a no-op, which is the behavior of v4.2 and earlier. When true, the set action results in the ArgumentOutOfRangeException.
Public fieldStatic memberMarkSavedEntitiesAsFetched
Flag (default: false) which controls if saved entities which aren't fetched back in the same call should be marked as Fetched instead of the default 'OutOfSync'. Setting this to true can save fetch roundtrips to the database to refetch data for the entity already in memory. However setting this setting to true can also cause getting the entity out of sync with the database because another thread has updated the same entity data. Use with care. It's recommended to leave it on its default value: false and only set this to true if you're sure the data in-memory reflects the entity data in the database.
Public fieldStatic memberScaleOverflowCorrectionActionToUse
The action to use when the build-in validation detects a scale overflow (e.g. scale of a field is 2, and the value to set the field to is 10.455, which has a scale of 3). Default is 'Truncate', which means that the overflow value will be truncated to the scale size. If validation is bypassed by setting BuildInValidationBypassMode to a value which makes the build-in validation to be bypassed, this setting has no effect.

Explicit interface implementationPrivate methodIEntityCoreGetAllRelations
Gets a list of all the EntityRelation objects the type of this instance has.
Explicit interface implementationPrivate methodIEntityCoreGetConcurrencyPredicate
Creates the requested predicate of the type specified. If no IConcurrencyPredicateFactory instance is stored in this entity instance, null is returned.
Explicit interface implementationPrivate methodIEntityCoreGetDependentRelatedEntities
Gets a collection of related entities referenced by this entity which this entity depends on (this entity is the FK side of their PK fields). These entities will have to be persisted before this entity during a recursive save.
Explicit interface implementationPrivate methodIEntityCoreGetDependingRelatedEntities
Gets a collection of related entities referenced by this entity which depend on this entity (this entity is the PK side of their FK fields). These entities will have to be persisted after this entity during a recursive save.
Explicit interface implementationPrivate methodIEntityCoreGetEntityDescription(Boolean)
Gets the entity description. This string is used in verbose trace messages. It will produce "EntityCore", if the passed in switch flag is false, to prevent performance loss due to reflection activity for trace results which will never be seen.
Explicit interface implementationPrivate methodIEntityCoreGetEntityDescription(Boolean, IEntityCore)
Gets the entity description. This string is used in verbose trace messages. It will produce "EntityCore", if verbose tracing is switched off for the GeneralSwitch, to prevent performance loss due to reflection activity for trace results which will never be seen.
Explicit interface implementationPrivate methodIEntityCoreGetEntityFactory
Returns a new ready to use factory for the type of this instance.
Explicit interface implementationPrivate methodIEntityCoreGetFieldByName
Helper method which performs a lookup in the fields based on the name specified.
Explicit interface implementationPrivate methodIEntityCoreGetInheritanceInfo
Gets the inheritance info for this entity, if applicable (it's then overriden) or null if not.
Explicit interface implementationPrivate methodIEntityCoreGetInheritanceInfoProvider
Gets the inheritance info provider instance of the project this entity instance is located in.
Explicit interface implementationPrivate methodIEntityCoreGetMemberEntityCollections
Gets a list of all entity collections stored as member variables in this entity. The contents of the list is used by the DataAccessAdapter to perform recursive saves. Only 1:n related collections are returned.
Explicit interface implementationPrivate methodIEntityCoreGetRelatedData
Gets all related data objects, stored by name. The name is the field name mapped onto the relation for that particular data element.
Explicit interface implementationPrivate methodIEntityCoreGetRelationsForFieldOfType
Gets the relation objects which represent the relation the fieldName specified is mapped on.
Explicit interface implementationPrivate propertyIEntityCoreIsDeserializing
Returns true if this entity instance is in the middle of a deserialization process, for example during a ReadXml() call. For internal use only.
Explicit interface implementationPrivate propertyIEntityCoreIsUpdateOnlyEntity
Gets a value indicating whether this instance is an update only entity. UpdateOnly entities are entities which are 'split off' from the main entity and only update rows in the database, never insert rows.
Explicit interface implementationPrivate propertyCode exampleIEntityCoreLLBLGenProEntityName
Returns the full name for this entity, which is important for the DAO to find back persistence info for this entity.
Explicit interface implementationPrivate propertyIEntityCoreLLBLGenProEntityTypeValue
Returns the EntityType enum value for this entity.
Explicit interface implementationPrivate propertyIEntityCoreLLBLGenProIsInHierarchyOfType
Gets the type of the hierarchy this entity is in.
Explicit interface implementationPrivate propertyIEntityCoreMarkedForDeletion
flag which is set when the entity is removed from an entity collection and added to a tracker.
Explicit interface implementationPrivate propertyIEntityCoreObjectID
Gets / sets the unique Object ID which is created at runtime when the entity is instantiated. Can be used for external caches.
Explicit interface implementationPrivate propertyIEntityCorePrimaryKeyFieldInfos
Gets the primary key field infos. Similar to PrimaryKeyFields, but this property doesn't trigger field creation.
Explicit interface implementationPrivate propertyIEntityCorePrimaryKeyFields
List of IEntityField2 references which form the primary key. Reads/Affects .Fields.PrimaryKeyFields. If possible use PrimaryKeyFieldInfos instead.
Explicit interface implementationPrivate methodIEntityCoreRejectChanges
Rejects the changes made to the fields. Used in databinding/service scenarios. Calls RejectChanges on the fields in this entity
Explicit interface implementationPrivate methodIEntityCoreRollbackFields
Replaces the current set of fields with the fields saved under the name specified. If no set of fields is found with the name specified an exception is thrown. Removes the entry after a succesful rollback.
Explicit interface implementationPrivate methodIEntityCoreSaveFields
Saves the current set of fields under the name specified in an internal hashtable. All data inside the field objects is preserved. If there is already a set of fields saved under the name specified, that set of fields is overwritten.
Explicit interface implementationPrivate methodIEntityCoreSetRelatedEntity
Sets the internal parameter related to the fieldname passed to the instance relatedEntity.
Explicit interface implementationPrivate methodIEntityCoreSetRelatedEntityProperty
Sets the related entity property to the entity specified. If the property is a collection, it will add the entity specified to that collection.
Explicit interface implementationPrivate propertyIEntityCoreTypeDefaultValueProviderToUse
Gets or sets the TypeDefaultValue provider to use. This object is used to provide default values for value typed fields which are null and not of type Nullable(Of T)
Explicit interface implementationPrivate methodIEntityCoreUnsetRelatedEntity(IEntityCore, String)
Unsets the internal parameter related to the fieldname passed to the instance relatedEntity. Reverses the actions taken by SetRelatedEntity()
Explicit interface implementationPrivate methodIEntityCoreUnsetRelatedEntity(IEntityCore, String, Boolean)
Unsets the internal parameter related to the fieldname passed to the instance relatedEntity. Reverses the actions taken by SetRelatedEntity()
Explicit interface implementationPrivate propertyITransactionalElementParticipatesInTransaction
Flag to check if the ITransactionalElement implementing object is participating in a transaction or not.
Explicit interface implementationPrivate propertyITransactionalElementTransaction
The ITransaction this ITransactionalElement implementing object is participating in. Only valid if ParticipatesInTransaction is true. If set to null, the ITransactionalElement is no longer participating in a transaction.
Explicit interface implementationPrivate methodITransactionalElementTransactionCommit
When the ITransaction in which this element participates is commited, this element can succesfully finish actions performed by this element. This method is called by ITransaction, you should not call it by yourself. When this element doesn't participate in a transaction it finishes the actions itself, calling this method is not needed.
Explicit interface implementationPrivate methodITransactionalElementTransactionRollback
When the ITransaction in which this element participates is rolled back, this element has to roll back its internal variables. This method is called by ITransaction, you should not call it by yourself.
