Interface CommentBookAssignmentSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface CommentBookAssignmentSession
extends OsidSession

This session provides methods to re-assign Comments to Books. A Comment may map to multiple Books and removing the last reference to a Comment is the equivalent of deleting it. Each Book may have its own authorizations governing who is allowed to operate on it.

Adding a reference of a Comment to another Book is not a copy operation (eg: does not change its Id ).
