Retrieving Class Definitions

Use the getClass method to get a CIM class. When a class is created, it inherits the methods and properties of the class it is derived from and all parent classes in the class hierarchy. The getClass method takes the Boolean argument localOnly. If localOnlyis true, this method returns only non-inherited properties and methods. If localOnly is false, all properties in the class are returned.

Example — Retrieving a Class Definition

The code shown in Example 4–18, uses the following methods to retrieve a class definition:

• CIMNameSpace – to create a new namespace

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

• CIMObjectPath – to create an object path, an object to contain the name of the class to retrieve

• getClass – to retrieve the class from the CIM Object Manager
