DocumentVersion

Description:
This class uniquely identifies an edition of a given document.

Remarks:

DocumentVersion consists of two parts - a GUID and an integer. The GUID is updated as new elements are created in the document, but it is not necessarily changed whenever any individual change is made to the document. The integer is updated when the document is saved.

The GUID will change as changes are made to a model, so it should not be treated as a static value.

This class does not contain any time information - you cannot compare two DocumentVersions and know which document is newer. It can be used to tell whether a document has changed since it was last inspected. See [!:Autodesk::Revit::DB::BasicFileInfo::GetDocumentVersion()]

Name	Return Type	Description
M Dispose()	None	Releases all resources used by the
M IsEqual(DocumentVersion)	bool	Checks whether two DocumentVersions are identical. They are identical if both the GUID and number of saves are equal. If two DocumentVersions are identical, they come from the same document, with the same set of changes.

Name	Return Type	Description
P IsValidObject	bool	Specifies whether the .NET object represents a valid Revit entity.
P NumberOfSaves	int	The number of times the document has been saved. The save number and GUID are both necessary to uniquely identify a document version.
P VersionGUID	Guid	The GUID portion of the DocumentVersion. The GUID is updated when changes are made to the document, but may not update with every change to the document. The GUID and save number are both necessary to uniquely identify a document version.
