EntityCoreTFields Methods

Adds the internals to context.

Will check if the entity should refetch itself. Will use the factory pattern trick. Refetching occurs when the fields are marked OutOfSync and thus not dirty.

Checks if the current value of the field on the index specified is null / not defined.

Determines whether this entity is a subType of the entity represented by the passed in enum value, which represents a value in the EntityType enum

Creates the auditor object for this entity. Routine is called when the entity is constructed. Implement in an entity class to set a particular entity auditor object at construction time. Use this method if you don't want to use LLBLGen Pro's build in dependency injection mechanism.

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.

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.

Creates a new entity factory instance related to this entity.

Creates entity fields object for this entity. Used in constructor to setup this entity in a polymorphic scenario.

Creates the ITypeDefaultValue instance used to provide default values for value types which aren't of type nullable(of T)

Creates the validator object for this entity. Routine is called when the entity is constructed. Implement in an entity class to set a particular entity validator object at construction time. Use this method if you don't want to use LLBLGen Pro's build in dependency injection mechanism.

Private CTor for deserialization

Destructs the synchronization setup between the related entity and this entity, related over the member specified.

Removes all saved field sets from the internal hashtable, clearing up space. This method is also called when an entity is saved.

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.

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.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Fixes deserialization empty references, because fieldinfo isn't serialized into the data.

Fixes deserialization empty references, because fieldinfo isn't serialized into the data.

A method to call OnPropertyChanged for all fields to signal to bound controls that all fields have been changed.

Gets the additional related data, next to the data returned by GetRelatedData. This method appends the additional related data to the passed in toAppendTo dictionary. Key is the property name, value is the entity object or entity collection represented by the property.

Gets a list of all the EntityRelation objects the type of this instance has.

Creates the requested predicate of the type specified. If no IConcurrencyPredicateFactory instance is stored in this entity instance, null is returned.

Gets the current value of the EntityField2 with the index fieldIndex.

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.

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.

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.

Gets the entity static meta data instance from the generated type.

Will retrieve all stored entity synchronization information for the passed in entity. If no information is stored, an empty hashtable is returned. All sync info is stored by fieldname

Gets the EntityType value as int for this entity.

Overrides the GetHashCode method. It will calculate a hashcode for this entity using the eXclusive OR of the hashcodes of the primary key fields in this entity. That hashcode is returned. If no primary key fields are present, the hashcode of the base class is returned, which will not be unique.

Gets the inheritance info provider instance of the project this entity instance is located in.

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.

ISerializable member. Does custom serialization so event handlers do not get serialized.

Gets all related data objects, stored by name. The name is the field name mapped onto the relation for that particular data element.

Gets the relation objects which represent the relation the fieldName specified is mapped on.

Gets the Type of the current instance.

Gets the value of the field with the index specified.

Marks the fields as dirty.

This method is called from the DataAccessAdapter method OnBeforeEntitySave(), unless that method is overriden. You can override this OnSave method instead, which allows you to make last minute changes, though keep the logic to do that in the entity.

Called after BeginEdit is succesfully called.

Method which will check if the caller is allowed to delete entities directly in the database.

Method which will check if the caller is allowed to insert entities directly into the database

Method which will check if the caller is allowed to update entities directly in the database.

Called after CancelEdit is succesfully called.

Method which will check if the caller is allowed to get the field value with the index specified.

Method which will check if the caller is allowed to fill this entity object with entity data from the database or not.

Method which will check if the caller is allowed to save this existing entity object

Method which will check if the caller is allowed to save this new entity object

Method which will check if the caller is allowed to set the field value with the index specified.

Called at the end of the deserialization constructor. Method is used when this object is deserialized. Override this method to tap into the deserialization sequence. (binary/soap formatter specific).

Called after EndEdit is succesfully called.

Event handler which is called by a related entity after that entity is persisted.

Called when the entity's contents has been changed.

Method which is called right after a field's value has been changed. There are a couple of methods called in the process of setting a field's value. This particular method is solely there to act on a field's value set action. It doesn't raise an event, though it receives the old and new value of the field. Not called if a fieldvalue set action failed. This method is called before changed events are raised.

Returns the FetchNewAuthorizationFailureResultHint as returned by the authorizer. Only called when the CanGetLoad failed (authorization failed, so load was denied)

Called at the end of GetObjectData. Method is used when this object is serialized. Override this method to tap into the serialization sequence. (binary/soap formatter specific).

Called right at the beginning of GetValue(), which is called from an entity field property getter

Called right at the end of GetValue(), which is called from an entity field property getter

Called when InitClassMembers is complete.

Called at the end of the initialization method. Raises Initialized event.

Called at the start of the initialization method. Raises Initializing event.

Called when a property changed value. Call this method to signal databound controls a property has changed.

Method which is called at the end of the SetRelatedEntity() method. Usable to act on the fact that a related entity has been set.

Method which is called at the end of the UnsetRelatedEntity() method. Usable to act on the fact that an entity has been dereferenced as a related entity by the containing entity.

Method which returns true if this auditor expects to have audit entities to persist and therefore needs a transaction. This method is called in the situation when there's no transaction going on though one should be started right before the single-statement action in the case if the auditor has entities to save afterwards. It's recommended to return true if the auditor might have audit entities to persist after an entity save/delete/direct update/direct delete/direct insert of entities. Default: false

Method which is called in the default clause of the SetRelatedEntityProperty method during the merge process of prefetch path fetches.

Called right at the beginning of SetValue(), which is called from an entity field property setter

Called right at the end of SetValue(), which is called from an entity field property setter

Called after the TransactionCommit method has been finished.

Called after the TransactionRollback method has been finished.

Method to validate the containing entity after it is loaded. This method is called after the entity has been fully loaded.

Method to validate the containing entity right after the entity's save action has been completed and the entity has been refetched (if applicable). Note for adapter users: if the entity wasn't set to be refetched, take into account that reading properties from the containing entity will result in an OutOfSync exception.

Method to validate the containig entity right beforethe entity's delete action will take place.

Method to validate the containing entity right before the save sequence for the entity will start. LLBLGen Pro will call this method right after the containing entity is selected from the save queue to be saved.

Method which will validate, using custom code supplied this class, the field with index fieldIndex if it should accept the specified value. 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.

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.

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.

Performs the dependency injection of related objects. This method will call the Create* methods to create validator, concurrency predicate factory and will then kick in the DependencyInjection functionality build into LLBLGen Pro. This method is called at the end of an entity's InitClassMembers method in the generated code.

Performs the desync setup when an FK field has been changed. The entity referenced based on the FK field will be dereferenced and sync info will be removed.

Routine which is used to perform tasks after a ReadXml() action on this entity instance was performed

Performs the related entity removal.

Method to perform post-fieldvalue set actions, like flagging this object as changed.

Post-processes the value to return from GetValue. Override this method to be able to post-process any value to return from an entity field's property.

Method which is meant to be overriden to pre-process a value right before it is set as a field's new value. In general you don't need to override this method. By default it's a no-op.

Will fill the entity and its containing members (recursively) with the data stored in the XmlNode passed in. The XmlNode has to be filled with Xml in the format written by IEntityCore.WriteXml() and the Xml has to be compatible with the structure of this entity collection.

Will set the passed in information as Entity sync information. If there is no sync information stored yet for the related entity then a new entry is created, otherwise it's info is added to the sync information of this entity, if it isn't already present. If there is already sync information for this field stored for another related entity, that information is removed.

Sets the EntityField2 on index fieldIndex to the new value value. Marks also the entityfields2 as dirty.

Accepts the changes made to the fields. Used in databinding/service scenarios. Calls AcceptChanges on the fields in this entity

Checks whether this instance has pending fk syncs. A pending FK sync is a sync which hasn't been used yet. If an entity has pending FK syncs, it has to be included into a save queue. Only syncs with entities in the passed in queue are considered. If a sync is with an entity which isn't in the passed in queue, the sync isn't honoured anyway, so the fk sync can be ignored.
