IPersistPropertyBag interface
Works with IPropertyBag and IErrorlog to define an individual property-based persistence mechanism.
Members
The IPersistPropertyBag interface inherits from IPersist. IPersistPropertyBag also has these types of members:
- Methods
Methods
The IPersistPropertyBag interface has these methods.
| Method | Description |
|---|---|
| InitNew | Informs the object that it is being initialized as a newly created object. |
| Load | Instructs the object to initialize itself using the properties available in the property bag, and to notify the provided error log object when errors occur. |
| Save | Instructs the object to save its properties to the given property bag, and optionally, to clear the object's dirty flag. |
Remarks
A mechanism such as IPersistStream gives an object an IStream in which to store its binary data, while IPersistPropertyBag provides an object with an IPropertyBag interface through which it can save and load individual properties. The object that implements IPropertyBag can then save those properties in various ways, such as name/value pairs in a text file. Errors encountered in the process (on either side) are recorded in an error log through IErrorlog. This error reporting mechanism works on a per-property basis instead of on all properties at once.
