35. (Roger Kumpf - HP) 30 Oct 2001 - Association classes have keys

whose types are references. These reference values must be

treated specially in the XML encoding, using the VALUE.REFERENCE

tag structure.

Pegasus had been passing reference values simply as String values.

For example, EnumerateInstanceNames returned KEYVALUEs of string

type rather than VALUE.REFERENCEs.

I've modified the XmlReader::getKeyBindingElement() and

CIMReference::instanceNameToXml() methods to read and write the

XML in the proper format. However, making that change required

that a CIMReference object be able to distinguish between a key

of String type and a key of reference type.

I've modified the String format of CIMReferences slightly to

allow efficient processing of references whose keys are also of

reference type. The "official" form uses the same encoding for

key values of String type and of reference type, and so it

would be necessary to retrieve the class definition and look up

the types of the key properties to determine how to treat the

key values. This is clearly too inefficient for internal

transformations between CIMReferences and String values.

The workaround is to encode a 'R' at the beginning of the value

for a key of reference type (before the opening '"'). This allows

the parser to know a priori whether the key is of String or

reference type.

In this example:

MyClass.Key1="StringValue",Key2=R"RefClass.KeyA="StringA",KeyB=10"

Property Key1 of class MyClass is of String type, and so it gets

the usual encoding. Key2 is a reference property, so the extra 'R'

is inserted before its encoded value. Note that this algorithm is

recursive, such that RefClass could include KeyC of reference type,

which would also get encoded with the 'R' notation.

The toString() method inserts the 'R' to provide symmetry. A new

KeyBinding type (REFERENCE) has been defined to denote keys in a

CIMReference that are of reference type. This KeyBinding type must

be used appropriately for CIMReference::ttoString() to behave

correctly.

The files that have been modified to make this change are

CIMReference.h, CIMReference.cpp, and CIMInstanceRep.cpp.

A result of this change is that instances names in the instance

repository will include this extra 'R' character. Thus, you will

need to repopulate your repository when you download the latest

CIMOM version.

Note that for user-facing uses of the String encoding of instance

names (such as might appear in MOF for static association

instances or in the CGI client), this solution is non-standard and

therefore unacceptable. It is likely that these points will need

to process the more expensive operation of retrieving the class

definition to determine the key property types.
