isMutable

public boolean isMutable()

Description copied from interface: Converter

PUBLIC: If the converter converts the value to a mutable value, i.e. a value that can have its' parts changed without being replaced, then it must return true. If the value is not mutable, cannot be changed without replacing the whole value then false must be returned. This is used within the UnitOfWork to determine how to clone.

                                                      Session session)

Description copied from interface: Converter

PUBLIC: Convert the databases' data representation of the value to the object's representation. For example this could convert between an sql.Time datatype and the Java Calendar type.
