Retrieving Class Definitions

The getClass method gets a CIM class. When a class is created, it inherits the methods and properties of the class from which it is derived, and all parent classes in the class hierarchy. The getClass method takes the localOnly Boolean argument.

• If localOnly is true, getClass returns only non-inherited properties and methods.

• If localOnly is false, getClass returns all properties in the class.

Example 3-16 Retrieving a Class Definition

This example uses the following methods to retrieve a class definition:

• CIMNameSpace – Create a new namespace

• CIMClient – Create a new client connection to the CIM Object Manager

• CIMObjectPath – Create an object path, which is an object to contain the name of the class to retrieve

• getClass – Retrieve the class from the CIM Object Manager
