EndOfTurn

Gets a default end-of-turn result.

DialogTurnResult

Remarks

This result indicates that a dialog (or a logical step within a dialog) has completed processing for the current turn, is still active, and is waiting for more input.

string

Inherited From Dialog.id

Method Details

beginDialog(DialogContext, O)

Called when the Dialog is started and pushed 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 | ConverterFactory

Parameters

property

Object

The key of the conditional selector configuration.

Returns

Converter | ConverterFactory

The converter for the selector configuration.

resumeDialog(DialogContext, DialogReason, any)

Called when a child Dialog completed its turn, returning control to this dialog.

function resumeDialog(dc: DialogContext, reason: DialogReason, result?: any): Promise<DialogTurnResult>

Parameters

dc

DialogContext

The DialogContext for the current turn of conversation.

reason

DialogReason

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

result

any

Optional. Value returned from the dialog that was called. The type of the value returned is dependent on the child dialog.

Returns

Promise<DialogTurnResult>

A Promise representing the asynchronous operation.

Inherited Method Details

configure(Record<string, unknown>)

Fluent method for configuring the object.

function configure(config: Record<string, unknown>): this

Parameters

config

Record<string, unknown>

Configuration settings to apply.

Returns

this

The Configurable after the operation is complete.

Inherited From Configurable.configure

continueDialog(DialogContext)

When overridden in a derived class, continues the dialog.

function continueDialog(dc: DialogContext): Promise<DialogTurnResult>

Parameters

dc

DialogContext

The context for the current dialog turn.

Returns

Promise<DialogTurnResult>

A promise resolving to the dialog turn result.

Remarks

Derived dialogs that support multiple-turn conversations should override this method. By default, this method signals that the dialog is complete and returns.

The DialogContext calls this method when it continues the dialog.

To signal to the dialog context that this dialog has completed, await DialogContext.endDialog before exiting this method.

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

getDependencies()

Gets the child Dialog dependencies so they can be added to the containers Dialog set.

function getDependencies(): Dialog<__type>[]

Returns

Dialog<__type>[]

The child Dialog dependencies.

Inherited From BaseInvokeDialog.getDependencies

getVersion()

An encoded string used to aid in the detection of bot changes on re-deployment.

function getVersion(): string

Returns

string

Unique string which should only change when dialog has changed in a way that should restart the dialog.

Remarks

This defaults to returning the dialogs id but can be overridden to provide more precise change detection logic. Any dialog on the stack that has its version change will result in a versionChanged event will be raised. If this event is not handled by the bot, an error will be thrown resulting in the bots error handler logic being run.

Returning an empty string will disable version tracking for the component all together.

Inherited From Dialog.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.
