Methods
| add |
Called once for each dialog within a library to give the dialog a chance to add its
|
| begin<T>(Session, T) | Called when a new dialog session is being started. |
| begin |
Binds an action to the dialog that will start another dialog anytime it's triggered. The new dialog will be pushed onto the stack so it does not automatically end the current task. The current task will be continued once the new dialog ends. The built-in prompts will automatically re-prompt the user once this happens but that behaviour can be disabled by setting the promptAfterAction flag when calling a built-in prompt. |
| cancel |
Binds an action to the dialog that will cancel the dialog anytime it's triggered. When canceled, the dialogs parent will be resumed with a resumed code indicating that it was canceled. |
| clone(Action |
Returns a clone of an existing ActionSet. |
| custom |
Binds a custom action to the dialog that will call the passed in onSelectAction handler when triggered. |
| dialog |
Called when a root dialog is being interrupted by another dialog. This gives the dialog that's being interrupted a chance to run custom logic before it's removed from the stack. The dialog itself is responsible for clearing the dialog stack and starting the new dialog. |
| dialog |
A child dialog has ended and the current one is being resumed. |
| end |
Binds an action that will end the conversation with the user when triggered. |
| find |
Called during the Library.findRoutes() call for each dialog on the stack to determine if any of the dialogs actions are triggered by the users utterance. |
| recognize(IRecognize |
Parses the users utterance and assigns a score from 0.0 - 1.0 indicating how confident the dialog is that it understood the users utterance. This method is always called for the active dialog on the stack. A score of 1.0 will indicate a perfect match and terminate any further recognition. When the score is less than 1.0, every dialog on the stack will have its recognizeAction() method called as well to see if there are any named actions bound to the dialog that better matches the users utterance. Global actions registered at the bot level will also be evaluated. If the dialog has a score higher then any bound actions, the dialogs replyReceived() method will be called with the result object returned from the recognize() call. This lets the dialog pass additional data collected during the recognize phase to the replyReceived() method for handling. Should there be an action with a higher score then the dialog the action will be invoked instead of the dialogs replyReceived() method. The dialog will stay on the stack and may be resumed at some point should the action invoke a new dialog so dialogs should prepare for unexpected calls to dialogResumed(). |
| reload |
Binds an action to the dialog that will cause the dialog to be reloaded anytime it's triggered. This is useful to implement logic that handle user utterances like "start over". |
| reply |
|
| select |
Selects the route that had the highest confidence score for the utterance. |
| trigger |
Binds an action to the dialog that will make it the active dialog anytime it's triggered. The default behaviour is to interupt any existing dialog by clearing the stack and starting the dialog at the root of the stack. The dialog being interrupted can intercept this interruption by adding a custom onInterrupted handler to their trigger action options. Additionally, you can customize the way the triggered dialog is started by providing a custom onSelectAction handler to your trigger action options. |
Method Details
addDialogTrigger(ActionSet, string)
Called once for each dialog within a library to give the dialog a chance to add its
triggerAction() to the libraries global action set. These triggers get mapped to
a beginDialogAction() that starts the dialog when the trigger condition is met.
function addDialogTrigger(actions: ActionSet, dialogId: string)Parameters
- actions
- ActionSet
Libraries global action set.
- dialogId
-
string
The fully qualified ID of the dialog to trigger.
begin<T>(Session, T)
Called when a new dialog session is being started.
function begin<T>(session: Session, args?: T)Parameters
- session
- Session
Session object for the current conversation.
- args
-
T
(Optional) arguments passed to the dialog by its parent.
beginDialogAction(string, string, IBeginDialogActionOptions)
Binds an action to the dialog that will start another dialog anytime it's triggered. The new dialog will be pushed onto the stack so it does not automatically end the current task. The current task will be continued once the new dialog ends. The built-in prompts will automatically re-prompt the user once this happens but that behaviour can be disabled by setting the promptAfterAction flag when calling a built-in prompt.
function beginDialogAction(name: string, id: string, options?: IBeginDialogActionOptions)Parameters
- name
-
string
Unique name to assign the action.
- id
-
string
ID of the dialog to start.
- options
- IBeginDialogActionOptions
(Optional) options used to configure the action. If matches is specified the action will listen for the user to say a word or phrase that triggers the action, otherwise the action needs to be bound to a button using CardAction.dialogAction() to trigger the action. You can also use dialogArgs to pass additional params to the dialog being started.
Returns
cancelAction(string, TextOrMessageType, ICancelActionOptions)
Binds an action to the dialog that will cancel the dialog anytime it's triggered. When canceled, the dialogs parent will be resumed with a resumed code indicating that it was canceled.
function cancelAction(name: string, msg?: TextOrMessageType, options?: ICancelActionOptions)Parameters
- name
-
string
Unique name to assign the action.
(Optional) message to send the user prior to canceling the dialog.
- options
- ICancelActionOptions
(Optional) options used to configure the action. If matches is specified the action will listen for the user to say a word or phrase that triggers the action, otherwise the action needs to be bound to a button using CardAction.dialogAction() to trigger the action.
Returns
clone(ActionSet)
Returns a clone of an existing ActionSet.
function clone(copyTo?: ActionSet)Parameters
- copyTo
- ActionSet
(Optional) instance to copy the current object to. If missing a new instance will be created.
Returns
customAction(IDialogActionOptions)
Binds a custom action to the dialog that will call the passed in onSelectAction handler when triggered.
function customAction(options: IDialogActionOptions)Parameters
- options
- IDialogActionOptions
The options used to configure the action. If matches is specified the action will listen for the user to say a word or phrase that triggers the action. Custom matching logic can be provided using onFindAction.
Returns
dialogInterrupted(Session, string, any)
Called when a root dialog is being interrupted by another dialog. This gives the dialog that's being interrupted a chance to run custom logic before it's removed from the stack. The dialog itself is responsible for clearing the dialog stack and starting the new dialog.
