The callback function that is fired before the CompareView object attempts to get the text for a page.
Page number to get the text from
LEADDocument to get the text from
A boolean indicating whether the CompareView should get the text for the page.
The default value is null, meaning the CompareView object will always get the text for every page. Add a callback function here to have more fine-grained control over which pages the CompareView actually gets the text for.
Note: The CompareView object only tracks text that is retrieved by calling DocumentViewerText.getDocumentPageText. It will not track text that is called directly from the document via DocumentPage.getText.
