CWsbCollectable
|

Class Description:
|
|||
|
|
|
|||
|
|
Base class for collectable objects that are persistable
|
|||
|
|
to/from stream, storage, or file. CWsbObject should be used instead of
|
|||
|
|
this object unless storage and/or file persistence is absolutely necessary!
|
|||
|
|
If the object is persisted as part of a parent
|
|||
|
|
object, then only the parent object (or its parent) needs to support
|
|||
|
|
persistence to storage and/or file.
