void Aspose::Words::Revision::Accept()

Examples

Shows how to work with revisions in a document.

auto builder = MakeObject<DocumentBuilder>(doc);

// Normal editing of the document does not count as a revision.
builder->Write(u"This does not count as a revision. ");

ASSERT_FALSE(doc->get_HasRevisions());

// To register our edits as revisions, we need to declare an author, and then start tracking them.
doc->StartTrackRevisions(u"John Doe", System::DateTime::get_Now());

builder->Write(u"This is revision #1. ");

ASSERT_TRUE(doc->get_HasRevisions());
ASSERT_EQ(1, doc->get_Revisions()->get_Count());

// This flag corresponds to the "Review" -> "Tracking" -> "Track Changes" option in Microsoft Word.
// The "StartTrackRevisions" method does not affect its value,
// and the document is tracking revisions programmatically despite it having a value of "false".
// If we open this document using Microsoft Word, it will not be tracking revisions.
ASSERT_FALSE(doc->get_TrackRevisions());

// We have added text using the document builder, so the first revision is an insertion-type revision.
SharedPtr<Revision> revision = doc->get_Revisions()->idx_get(0);
ASSERT_EQ(u"John Doe", revision->get_Author());
ASSERT_EQ(u"This is revision #1. ", revision->get_ParentNode()->GetText());

// Adding a new revision places it at the beginning of the revision collection.

ASSERT_EQ(2, doc->get_Revisions()->get_Count());

// Insert revisions show up in the document body even before we accept/reject the revision.
// Rejecting the revision will remove its nodes from the body. Conversely, nodes that make up delete revisions
// also linger in the document until we accept the revision.
ASSERT_EQ(u"This does not count as a revision. This is revision #1.", doc->GetText().Trim());

// Accepting the delete revision will remove its parent node from the paragraph text
// and then remove the collection's revision itself.

ASSERT_EQ(8, doc->get_Revisions()->get_Count());
ASSERT_EQ(u"This is revision #2.\rThis is revision #1. \rThis is revision #2.", doc->GetText().Trim());

// The moving revision is now at index 1. Reject the revision to discard its contents.
