processTextAction abstract method
Returns a Future that resolves to a String when the text action returns a transformed text or null when the text action did not return a transformed text.
The id
parameter is the text action unique identifier returned by
queryTextActions.
The text
parameter is the text to be processed.
The readOnly
parameter indicates that the transformed text, if it exists,
will be used as read-only.
