Key Classes and Interfaces

Use

The following are the major OBN classes and interfaces:

Class/Interface	Description
`IOBNService`	The interface that enables you to query for OBN data. There are two ways to do this: Resolving Container: When you know the business object you want to explore, get a resolving container for the specific business object. Analyzer: When you want to find the related business objects and operations, for example, for a specific user, page or role, get an analyzing handler. This interface is also used to obtain an `OBNFactory` object.
`OBNFactory`	The factory class that creates basic OBN-related objects.
`IOBNMetadata`	The interface that represents a set of OBN metadata, including business object, operation, parameters and other data. Use this interface to trigger navigation or query OBN data for the specified metadata.
`IOBNResolvingContainer`	The interface that enables you to get OBN information for a specific set of OBN metadata.

The following interfaces enable you to query the OBN implementations for the current user, as described in Querying Content with the Analyzer :

IOBNAnalyzingHandler

The interface that offers a set of methods to create basic objects for analyzing OBN data.

IOBNAnalyzingBOFilter

The interface that defines filtering rules for business objects returned by the OBN analyzer.

For example, you can specify to return only context business objects.

IOBNAnalyzingScope

The interface that defines the scope of the OBN analysis.

A scope is a list of locations in the PCD, such as a role, folder, workset or page.
