Initializes a new instance.

Implement to create the columns. This method will be called each time the inputs of the producer changes or the GetConfigureColumnsTriggerCore fires. The purpose is to add the metadata about each output column that should be created and which inputs it has to the configurator. If this is the first call to the method those columns will be created. If there are already existing output columns those will be matched against those provided in the configurator, primarily on external id, and those no longer present will be removed, new ones added and those still remaining updated with the new information provided.

Creates an event relay. An event relay is a property in the document model which propagates event. An event is raised for the event relay whenever when the trigger returned by the specified dependencyDeclarer fires.

Creates an VirtualColumnInputCollection associated with the given inputIdentifier.

Creates an UndoableList T  and assigns it to the specified field. The UndoableList T  will have the specified propertyName.

Creates an UndoableSet T  and assigns it to the specified field. The UndoableSet T  will have the specified propertyName.

Creates an UndoableCrossReferenceProperty T  and assigns it to the specified field. The UndoableCrossReferenceProperty T  will have the specified propertyName and initialValue.

Creates an UndoableProperty T  and assigns it to the specified field. The UndoableProperty T  will have the specified propertyName and initialValue.

Creates an UndoableDictionary TKey, TValue  and assigns it to the specified field. The UndoableDictionary TKey, TValue  will have the specified propertyName.

Creates an UndoableKeyedCollection TKey, TNode  and assigns it to the specified field. The UndoableKeyedCollection TKey, TNode  will have the specified propertyName.

Creates a read-only property of type T and assigns it to the specified field.

Creates a runtime constant. A runtime constant is a property in the document model whose value is computed once when first accessed. The value is then disposed along with the DocumentNode.

Creates a RuntimeProperty T .

Creates a RuntimeProperty T .

Override this method to declare handlers of internal events.

Deserializes an UndoableCrossReferenceProperty T  with value of type T stored in info with key propertyName.

Deserializes an UndoableList T  with value of type T stored in info with key given by propertyName.

Deserializes an UndoableProperty T  with value of type T stored in info with key propertyName.

Deserializes an UndoableSet T  with value of type T stored in info with key propertyName.

Deserializes an UndoableDictionary TKey, TValue  stored in info with key given by propertyName.

Deserializes an UndoableKeyedCollection TKey, TNode  stored in info with key given by propertyName.

Deserializes a read-only property of type T stored in info with key propertyName.

Returns a copy of the sub tree spanned from this node that has the same outwards non-owning references. The returned copy will be in state New and is intended to be attached to the document immediately.

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

Implement to return an object that serves as a cache key for the producer. The returned object should implement Equals so that it returns a different value for each model state that influences if the resultvalue returned for a given VirtualValueRequest is different. The object should also implement GetHashCode to match that. This method will be called when GetCacheKeyTriggerCore  fires.

Override this method to provide a trigger that fires when the settings in the producer changes so that a result value returned for a given VirtualValueRequest changes.

Implement this method to provide a trigger that fires when the output columns needs to be created or changed. This trigger should not include the inputs changing as that is added automatically by the framework.

If the producer has credentials that needs to be filled in by the user, then this method should be implemented to return a credentialsmodel that has been registered with an appropriate UI-component in the ViewRegistry. The default implementation returns null which means no credentials are necessary.

Gets the inputs for the given identifier.

Implement this to indicate if the producer needs prompting in order to set up its parameters, not including credentials.

Can be used in the deserialization constructor to get the type name that the class corresponding to this class had when it was originally serialized. Will return null if the specified caller type has no correspondence in the serialized information

Can be used in the deserialization constructor to get the persistence version that this class was marked with when it was originally serialized. Will return null if the specified caller type has no correspondence in the serialized information

Override this method to provide services accessible from this node and its descendants. If you can not provide the requested service, you should call base.GetService which relays the request to the owner or to the AnalysisApplication if no owner is set.

Override this method to specify the worker threading model of the producer's virtual value worker.

Gets the Type of the current instance.

Starts an internal transaction on the document model by executing the specified executor delegate.

Creates a shallow copy of the current Object.

Allows a node to configure itself to the surrounding document.

Allows a node to configure itself to the surrounding document.

Allows a node to reconfigure itself to a new part of the surrounding document.

Allows a node to reconfigure itself to a new part of the surrounding document.

Prompts the registered ui to fill in any settings if allowed and GetNeedsPromptingCore determines that prompting is necessary.

Serializes an Undoable*Property with value of type T storing it in info with key property.Name.

Serializes an UndoableList with values of type T storing it in info with key list.Name.

Serializes an UndoableProperty with value of type T storing it in info with key property.Name.

Serializes an UndoableSet storing it in info with key given by the property name of the set.

Serializes an UndoableDictionary storing it in info with key given by the property name of the dictionary.

Serializes an UndoableKeyedCollection TKey, TNode  storing it in info with key given by the property name of the keyedCollection.

Serializes a read-only property of type T stored in info with key propertyName.

Sets the inputs for the given identifier. Setting the inputs causes configurecolumnscore to happen. Any previous inputs for this identifier are replaced.

Validates that the node is attached.

Gets the signatures for any input columns that are possible to choose from as inputs. In a typical scenario they would be exposed either to the end user in the UI or through the api for an apiuser to select among. Once some are selected they can be used in SetInputs(VirtualColumnInputIdentifier, IEnumerable DataColumnSignature ) to set the inputs for a particular VirtualColumnInputIdentifier. Each output column is associated with an identifier and thus the set inputs in ConfigureColumnsCore(VirtualColumnsConfigurator).

Gets the produced columns.

Gets the context of this node.

Gets a value indicating whether this node is attached.

Gets a collection of methods for executing transactions on the document.

Gets the type identifier for the producer.
