IVssWriterComponents class (vswriter.h)

The IVssWriterComponents interface is a C++ (not COM) interface that contains methods used to obtain and modify component information (in the form of IVssComponent objects) associated with a given writer but stored in a requester's Backup Components Document.

The CVssWriter base class is responsible for passing an instance of the IVssWriterComponents interface to the following event handlers:

• CVssWriter::OnPrepareBackup
• CVssWriter::OnBackupComplete
• CVssWriter::OnPreRestore
• CVssWriter::OnPostRestore
• CVssWriter::OnPostSnapshot

In addition, an instance of the IVssWriterComponentsExt interface, which implements a requester-side version of the IVssWriterComponents interface, is returned by IVssBackupComponents::GetWriterComponents.

IVssWriterComponents defines the following methods.

Method	Description
GetComponent	Returns the components belonging to a given writer instance.
GetComponentCount	Returns the number of components belonging to a given writer instance.
GetWriterInfo	Returns the instance and class identifier of the writer responsible for the components.

Methods

The IVssWriterComponents class has these methods.

IVssWriterComponents::GetComponent The GetComponent method returns an IVssComponent interface to one of a given writer's components explicitly stored in the Backup Components Document.
IVssWriterComponents::GetComponentCount The GetComponentCount method returns the number of a given writer's components explicitly stored in the Backup Components Document.
IVssWriterComponents::GetWriterInfo The GetWriterInfo method gets the instance and class identifier of the writer responsible for the components.
