Example — Creating a CIM Class

The example in Example 4–22 creates a new CIM class in the default namespace (root\cimv2) on the local host. This class has two properties, one of which is the key property for the class. The example then uses the newInstance method to create an instance of the new class.

Example 4–22 Creating a CIM Class (CIMClass)

{
...
    /* Connect to the root\cimv2 namespace 
    on the local host and create a new class called myclass */

    // Connect to the default namespace on local host. 
    CIMClient cc = new CIMClient();
 
    // Construct a new CIMClass object 
    CIMClass cimclass = new CIMClass();

    // Set CIM class name to myclass. 
    cimclass.setName("myclass"); 

    // Construct a new CIM property object
    CIMProperty cp = new CIMProperty(); 

    // Set property name
    cp.setName("keyprop"); 
     
    // Set property type to one of the predefined CIM data types.
    cp.setType(CIMDatatype.getPredefinedType(CIMDataType.STRING)); 
     
    // Construct a new CIM Qualifier object
    CIMQualifier cq = new CIMQualifier(); 
     
    // Set the qualifier name
    cq.setName("key"); 
     
    // Add the new key qualifier to the property
    cp.addQualfier(cq); 
     
    /* Create an integer property initialized to 10 */
     
    // Construct a new CIM property object
    CIMProperty mp = new CIMProperty();
     
    // Set property name to myprop
    mp.setName("myprop"); 
     
    // Set property type to one of the predefined CIM data types.
    mp.setType(CIMDatatype.getPredefinedType(CIMDataType.SINT16)); 
     
    // Initialize mp to a CIMValue that is a new Integer object 
    // with the value 10. The CIM Object Manager converts this 
    // CIMValue to the CIM Data Type (SINT16) specified for the 
    // property in the mp.setType statement in the line above. 
    // If the CIMValue (Integer 10) does not fall within the range 
    // of values allowed for the CIM Data Type of the property
    // (SINT16), the CIM Object Manager throws an exception.  
    mp.setValue(new CIMValue(new Integer(10)));
     
    /* Add the new properties to myclass and call 
    the CIM Object Manager to create the class. */
     
    // Add the key property to class object
    cimclass.addProperty(cp); 
     
    // Add the integer property to class object
    cimclass.addProperty(mp); 
     
    /* Connect to the CIM Object Manager and pass the new class */
    cc.createClass(new CIMObjectPath(),cimclass);
     
    // Create a new CIM instance of myclass
    ci = cc.newInstance(); 
     
    // If the client connection is open, close it.
		if(cc != null) {
        cc.close();
    }
