interface provides methods for saving and loading objects that use a simple
serial stream for their storage needs. The primary purpose of this interface is
to support OLE moniker implementations. Each of the OLE-provided moniker
interfaces provide an IPersistStream
implementation through which the moniker saves or loads itself. An instance
of the OLE generic composite moniker class calls the IPersistStream
methods of its component monikers to load or save the components in the
proper sequence in a single stream.
OLE containers with embedded and linked component objects do not use this
interface; they use the IPersistStorage
When to Implement
Typically, applications do not implement the IPersistStream
interface. However, the IMoniker
interface is derived from the IPersistStream
interface, so you must implement the IPersistStream
interface if you are implementing a new moniker class.
When to Use
Typically, applications do not use the IPersistStream
interface directly. The default link handler uses the IPersistStream
interface to save and load the monikers that identify the link source. These
monikers are stored in a stream in the storage for the linked object. If you
are writing a custom link handler for your class of components, you will need to
use the IPersistStream
interface to load and save these monikers.
Methods in Vtable Order
||Checks the object for changes since it was last saved.
||Initializes an object from the stream where it was previously saved.
||Saves an object into the specified stream and indicates whether the object
should reset its dirty flag.
||Return the size in bytes of the stream needed to save the object.
