Methods
Name | Description | |
---|---|---|
ConfigureColumnsCore |
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.
| |
CreateEventRelay |
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.
(Inherited from DocumentNode.) | |
CreateInputs |
Creates an VirtualColumnInputCollection associated with the given inputIdentifier.
| |
CreateProperty T (PropertyName, UndoableList T ) |
Creates an UndoableList T and assigns it to the specified field.
The UndoableList T will have the specified propertyName.
(Inherited from DocumentNode.) | |
CreateProperty T (PropertyName, UndoableSet T ) |
Creates an UndoableSet T and assigns it to the specified field.
The UndoableSet T will have the specified propertyName.
(Inherited from DocumentNode.) | |
CreateProperty TNode (PropertyName, UndoableCrossReferenceProperty TNode , TNode) |
Creates an UndoableCrossReferenceProperty T and assigns it to the specified field.
The UndoableCrossReferenceProperty T will have the specified propertyName and initialValue.
(Inherited from DocumentNode.) | |
CreateProperty T (PropertyName, UndoableProperty T , T) |
Creates an UndoableProperty T and assigns it to the specified field.
The UndoableProperty T will have the specified propertyName and initialValue.
(Inherited from DocumentNode.) | |

whose value is computed once when first accessed. The value is then disposed
along with the DocumentNode.

DeserializeProperty T (SerializationInfo, StreamingContext, PropertyName, UndoableCrossReferenceProperty T ) |
Deserializes an UndoableCrossReferenceProperty T with value of type T
stored in info with key propertyName.

stored in info with key propertyName.
(Inherited from DocumentNode.) | |
DuplicateSubtree T | 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. (Inherited from DocumentNode.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetCacheKeyCore |
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.
| |
GetCacheKeyTriggerCore |
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.
| |
GetConfigureColumnsTriggerCore |
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.
| |
GetCredentialsModelCore |
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.
| |
GetInputs |
Gets the inputs for the given identifier.
| |
GetNeedsPromptingCore |
Implement this to indicate if the producer needs prompting
in order to set up its parameters, not including credentials.
| |
GetPersistedTypeName | 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
(Inherited from DocumentNode.) | |
GetPersistedVersion | 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
(Inherited from DocumentNode.) | |
GetService | 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.
(Inherited from Node.) | |
GetThreadingModelCore | Override this method to specify the worker
threading model of the producer's virtual value worker.
| |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
InternalTransaction |

Allows a node to reconfigure itself to a new part of the surrounding document.
(Inherited from DocumentNode.) | |
OnReconfigured |
Allows a node to reconfigure itself to a new part of the surrounding document.
(Inherited from DocumentNode.) | |
Prompt |
Prompts the registered ui to fill in any settings if allowed and GetNeedsPromptingCore determines that
prompting is necessary.

storing it in info with key property.Name.
(Inherited from DocumentNode.) | |

with key given by the property name of the keyedCollection.

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

inputs for this identifier are replaced.
| |

Properties
Name | Description | |
---|---|---|
AvailableInputs |
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).
| |
Columns |
Gets the produced columns.
| |
Context |
Gets the context of this node.
(Inherited from DocumentNode.) | |
IsAttached |
Gets a value indicating whether this node is attached.
(Inherited from DocumentNode.) | |
Transactions |
Gets a collection of methods for executing transactions on the document.
(Inherited from DocumentNode.) | |
TypeId | Gets the type identifier for the producer.
