EndOfTurn
Gets a default end-of-turn result.

Method Details
beginDialog(DialogContext, O)
Starts a new Dialog and pushes it onto the dialog stack.
function beginDialog(dc: DialogContext, _options?: O): Promise<DialogTurnResult>Parameters
- dc
-
DialogContext
The DialogContext for the current turn of conversation.
- _options
-
O
Optional. Initial information to pass to the dialog.
Returns
Promise<DialogTurnResult>
A Promise representing the asynchronous operation.
getConverter(Object)
function getConverter(property: Object): Converter | ConverterFactoryParameters
- property
-
Object
The key of the conditional selector configuration.
Returns
Converter | ConverterFactory
The converter for the selector configuration.
getDependencies()
Gets the child Dialog dependencies so they can be added to the containers Dialog set.
function getDependencies(): Dialog[]Returns
Dialog[]
The child Dialog dependencies.
Inherited Method Details
configure(Record<string, unknown>)
Fluent method for configuring the object.
function configure(config: Record<string, unknown>): thisParameters
- config
-
Record<string, unknown>
Configuration settings to apply.
Returns
this
The Configurable after the operation is complete.
Inherited From Configurable.configure
continueDialog(DialogContext)
Called when the Dialog is continued, where it is the active dialog and the user replies with a new activity.
function continueDialog(dc: DialogContext): Promise<DialogTurnResult>Parameters
- dc
-
DialogContext
The DialogContext for the current turn of conversation.
Returns
Promise<DialogTurnResult>
A Promise representing the asynchronous operation.
Inherited From ActionScope.continueDialog
endDialog(TurnContext, DialogInstance, DialogReason)
When overridden in a derived class, performs clean up for the dialog before it ends.
function endDialog(_context: TurnContext, _instance: DialogInstance, _reason: DialogReason): Promise<void>Parameters
- _context
-
TurnContext
The context object for the turn.
- _instance
-
DialogInstance
Current state information for this dialog.
- _reason
-
DialogReason
The reason the dialog is ending.
Returns
Promise<void>
Remarks
Derived dialogs that need to perform logging or cleanup before ending should override this method. By default, this method has no effect.
The DialogContext calls this method when the current dialog is ending.

Inherited From Dialog.endDialog
getVersion()
Gets a unique string which represents the version of this dialog. If the version
changes between turns the dialog system will emit a DialogChanged event.
function getVersion(): stringReturns
string
Unique string which should only change when dialog has changed in a
way that should restart the dialog.
Inherited From ActionScope.getVersion
onDialogEvent(DialogContext, DialogEvent)
Called when an event has been raised, using DialogContext.emitEvent(), by either the current dialog or a dialog that the current dialog started.
function onDialogEvent(dc: DialogContext, e: DialogEvent): Promise<boolean>Parameters
- dc
-
DialogContext
The dialog context for the current turn of conversation.
- e
-
DialogEvent
The event being raised.
Returns
Promise<boolean>
True if the event is handled by the current dialog and bubbling should stop.
Inherited From Dialog.onDialogEvent
repromptDialog(TurnContext, DialogInstance)
When overridden in a derived class, reprompts the user for input.
function repromptDialog(_context: TurnContext, _instance: DialogInstance): Promise<void>Parameters
- _context
-
TurnContext
The context object for the turn.
- _instance
-
DialogInstance
Current state information for this dialog.
Returns
Promise<void>
Remarks
Derived dialogs that support validation and re-prompt logic should override this method. By default, this method has no effect.
The DialogContext calls this method when the current dialog should re-request input from the user. This method is implemented for prompt dialogs.

Inherited From Dialog.repromptDialog
resumeDialog(DialogContext, DialogReason, any)

function resumeDialog(dc: DialogContext, _reason: DialogReason, result?: any): Promise<DialogTurnResult>Parameters
- dc
-
DialogContext
The DialogContext for the current turn of conversation.
- _reason

(xref:botbuilder-dialogs.DialogReason), reason why the dialog resumed.
- result
-
