DialogDependencies interface
Interface for dialogs that have child dialog dependencies.
Example
class MyComplexDialog extends Dialog implements DialogDependencies {
private textPrompt = new TextPrompt('textPrompt');
private confirmPrompt = new ConfirmPrompt('confirmPrompt');
getDependencies(): Dialog[] {
return [this.textPrompt, this.confirmPrompt];
}
}
Remarks
Implement this interface on dialog classes that need to register child dialogs with their parent dialog set. When a dialog implementing this interface is added to a DialogSet, the DialogSet will automatically call getDependencies() and add all returned child dialogs to itself, ensuring proper dialog registration and avoiding runtime errors when the dialog tries to call child dialogs.
This is particularly useful for complex dialogs that compose multiple sub-dialogs or for dialog libraries that need to ensure their dependencies are available.
Methods
| get |
Returns an array of child dialogs that this dialog depends on. |
Method Details
getDependencies()
Returns an array of child dialogs that this dialog depends on.
function getDependencies(): Dialog<{}>[]Returns
Dialog<{}>[]
An array of Dialog instances that should be added to the parent DialogSet.
Remarks
This method is called automatically by DialogSet.add() when a dialog implementing this interface is added to the set. All returned dialogs will be recursively added to the same DialogSet, ensuring they are available when needed during dialog execution.
The returned dialogs should be the actual Dialog instances that will be called by this dialog, not new instances. This ensures proper dialog lifecycle management and state consistency.
