Retrieving Class Definitions

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

• If localOnly is true, getClass returns only noninherited properties and methods.

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

Example 4–16 Retrieving a Class Definition

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

• CIMNameSpace – Create a new name space

• 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
