The following table describes how CIM elements map to elements of the Java programming language.
Table 7–2 How CIM Elements Map to Java Elements
CIM Element |
Java Element |
---|---|
Class |
The CIM class name is used as the basis for the name of the generated Java source files. The generated Java classes follow the same inheritance as defined in the class-subclass relationships in the MOF. |
Property |
An accessor and a mutator method are created for each CIM property. The CIM property name is used as the basis for the associated accessor and mutator methods. |
Method |
For each CIM method, a comparable Java method is created. The method name is used as the basis for the related Java method name. The return value is the same, accounting for the mapping to a Java data type. Input and output parameters are used as arguments to the Java method. Output parameters are not directly included in the method signature. Instead, output parameters are encapsulated in an output container object that is included as a method parameter. |
Qualifier | |
Association |
Nothing specific required. |
Indication |
Nothing specific required. |
Reference |
For each CIM reference, a reference to a generated Java interface is created. |
Trigger |
Nothing specific required. |
Schema |
Nothing specific required. |
The following table describes how CIM data types map to Java data types.

The following table lists the meta qualifiers that refine the definition of the meta constructs in the model. These qualifiers are mutually exclusive and are used to refine the actual usage of an object class or property declaration within the MOF syntax.

The following table lists the standard qualifiers and the effect that these qualifiers have on the mapping of a CIM object to a bean. There is no support for optional qualifiers. Javadoc API documentation is produced for each interface and class based on this mapping.
Table 7–5 Standard Qualifiers
Qualifier |

Meaning |
---|---|---|
ABSTRACT |
Class, Association, Indication |
The class is abstract and has no effect on the Java programming language interfaces. |
DESCRIPTION |
Any |
The information that is provided generates Javadoc comments in the source file. |
DISPLAYNAME |
Property |
An accessor method for the display name is created: public String displayNameForProperty(); |
IN |
Parameter |
Determines the method signature. |
OUT |
Parameter |
Determines the method parameter signature and return values. |
TERMINAL |
Class |
Class or interface is final. |
UNITS |
Property, Method, Parameter |
Another accessor method is created: public String getpropertyUnits(); |
VALUEMAP |
Property, Method, Parameter |
Beans contain generated constants for each property in a CIM class that has a CIM ValueMap or a Values qualifier. The way in which the constant name and constant value are obtained to generate these class variables depends on the data type of the property and the qualifiers that the property possesses. Note – The ValueMap and Values qualifiers as defined in the CIM specification have meanings contrary to what the qualifier names might imply. ValueMap defines the legal set of values for a property. Values provides translation between an integer value and a string. |
VALUES |
Property, Method, Parameter |
Beans contain generated constants for each property in a CIM class that has a CIM ValueMap or a Values qualifier. The way in which the constant name and constant value are obtained to generate these class variables depends on the data type of the property and qualifiers that the property possesses. Note – The ValueMap and Values qualifiers as defined in the CIM specification have meanings contrary to what the qualifier names might imply. ValueMap defines the legal set of values for a property. Values provides translation between an integer value and a string. |
