The actual content changes. The content changes describe single state changes to the document. So if there are two content changes c1 (at array index 0) and c2 (at array index 1) for a document in state S then c1 moves the document from S to S' and c2 from S' to S''. So c1 is computed on the state S and c2 is computed on the state S'.
To mirror the content of a document using change events use the following approach:
TextDocumentContentChangeEvents in a single notification in the order
you receive them.The document that did change. The version number points to the version after all provided content changes have been applied.
The change text document notification's parameters.
