All objects that are a part of a collection have a similar set of methods and properties, which are all or a combination of the following.
| Method | Description |
|---|---|
| Save | Saves all the objects within the collection to
persistent storage. Modifications made to the collection will not
be saved until after this method is called.
The Save method is recursive, so calling the Save method of the collection will save every object within the collection. |
| Refresh | Reads the latest saved configuration settings from persistent storage and applies them to the object collection. The Refresh method does not check whether there are any unsaved changes made to the objects, so all changes made after the last Save method call will be lost. The Refresh method is useful when you want to cancel changes that have been made but not yet saved with the Save method. |
| Add | Adds an object to the collection, and returns a
reference to the newly created object. This method takes a string
parameter that identifies the new object. The string parameter can
be used later to retrieve the object by using the Item
method.
To save this new object to persistent storage, call the Save method. |
| Remove | Removes an object from the collection. This method takes a string parameter or index of the object to be removed from the collection. |
| Item | Returns the given object from the collection. This method retrieves an object by an index that is an integer value. It may also retrieve the object by using the name of the object, which is a string value. |
| Property | Description |
|---|---|
| Count | Returns an integer value of the number of objects in the collection. |
| VendorParametersSets | Retrieves a reference to an object for storing and loading of custom data into the collection's storage. The VendorParametersSets property is designed to integrate third-party extensions into ISA Server. |
While most collections of objects work in the same way, see individual collection reference pages for particular descriptions.
Note With Visual C++, you can browse a collection to find a particular item by using the _NewEnum property or the Item method. ISA collections include the _NewEnum property and the Item method. The Item method is described in the ISA Server SDK reference. For more information about _NewEnum, see the ISA Server SDK msfpccom.idl file.
In Visual Basic, you do not need to use the _NewEnum property, because it is automatically used in the implementation of For Each ... Next.
