    This class defines the external client operations for Pegasus These
    operations are based on the WBEM operations defined in the DMTF CIM
    CIMOperations over HTTP operations Specification. They duplicate the names,
    functions, and parameters of those CIMOperations. Each WBEM operation is a
    method in this class.

    This library (operations.h) defines the external APIs for the Pegasus MSB.
    These are synchronous calls and match the operations defined by the DMTF in
    the document "Specification for CIM CIMOperations over HTTP" Version 1.0
    with
    errata

    The CIMOperations class is used by other classes such as the client,
    provider, and repository classes to instantiate the operations interfaces.

	@param className The <TT>className</TT> input parameter defines the name
	of the Class to be retrieved.

	@param localOnly If the <TT>localOnly</TT> input parameter is true, this
	specifies that only CIM Elements (properties, methods and qualifiers)
	overriden within the definition of the Class are returned.  If false,
	all elements are returned.  This parameter therefore effects a CIM
	Server-side mechanism to filter certain elements of the returned object
	based on whether or not they have been propagated from the parent Class
	(as defined by the PROPAGATED attribute).

	@param includeQualifiers If the <TT>includeQualifiers</TT> input
	parameter is true, this specifies that all Qualifiers for that Class
	(including Qualifiers on the Class and on any returned Properties,
	Methods or CIMMethod Parameters) MUST be included as <QUALIFIER>
	elements in the response.  If false no <QUALIFIER> elements are
	present in the returned Class.

	parameter is true, this specifies that the CLASSORIGIN attribute MUST be
	present on all appropriate elements in the returned Class. If false, no
	CLASSORIGIN attributes are present in the returned Class.

	@param propertyList If the <TT>propertyList</TT> input parameter is not
	NULL, the members of the array define one or more CIMProperty names. The
	returned Class MUST NOT include elements for any Properties missing from
	this list. Note that if LocalOnly is specified as true this acts as an
	additional filter on the set of Properties returned (for example, if
	CIMProperty A is included in the PropertyList but LocalOnly is set to
	true and A is not local to the requested Class, then it will not be

        the Class are created as new elements of the Instance.

        <LI>Any CIMQualifier previously defined in the Instance but not
        defined in the Class, and which is not present in the
        <TT>ModifiedInstance</TT> parameter, is removed from the Instance.

        <LI>If a CIMProperty is specified in the <TT>ModifiedInstance</TT>
        parameter, the value assigned to that property therein
        (including NULL) becomes the value of the property for the Instance.
        Note that it is a Client error to specify a CIMProperty that does not
        belong to the Class.

        <LI>If a CIMProperty of the Class is not specified in the Instance,
        then that CIMProperty is inherited without modification by the Instance
        (so that any previous changes to that CIMProperty in the Instance are
        lost).
        <LI>Any Qualifiers defined in the Class with a <TT>TOINSTANCE</TT>
        attribute value of <TT>true</TT> appear in the Instance (it is not
        possible remove a propagated CIMQualifier from an Instance. Qualifiers
        in the Class with a <TT>TOINSTANCE</TT> attribute value of <TT>false</TT>
        MUST NOT be propagated to the Instance.
        <LI>Any CIMQualifier propagated from the Class cannot be modified by the
        Server if the <TT>OVERRIDABLE</TT> attribute of that CIMQualifier was
        set to <TT>false</TT> in the Class. It is a Client error to specify such

        type and flavor attribute settings of the
        <TT>&lt;QUALIFIER&gt;</TT> element, and the value of the CIMQualifier).
        <LI>Any CIMQualifier propagated from the Class cannot be modified in
        the Instance if the <TT>OVERRIDABLE</TT> attribute of that CIMQualifier
        was
        set to <TT>false</TT> in the Class. It is a Client error to specify such
        a CIMQualifier in the <TT>ModifiedInstance</TT> with a different

    Only elements (properties, methods and qualifiers) defined or

    included in the name part of the method response, but not in the value
    information.

    parameter is <TT>true</TT>, this specifies that, for each
    returned Instance of the Class, all properties of the Instance MUST
    be present (subject to constraints imposed by the other
    parameters), including any which were added by subclassing the specified
    Class. If <TT>false</TT>, each returned Instance includes only
    properties defined for the specified Class.

    The Enumerate Instances operation returns the same number of instances
    regardless of whether or not the DeepInheritance flag is set.  The
    DeepInheritance flag is only used to determine whether or not the subclass
    property values should be returned.

    @param includeQualifiersIf the <TT>includeQualifiers</TT> input
    parameter is <TT>true</TT>, this specifies that all Qualifiers
    for each Instance (including Qualifiers on the Instance

    <TT>&lt;QUALIFIER&gt;</TT> elements are present in each

    @param nameSpace The nameSpace parameter is a string that defines the target
    namespace. See defintion of

    @param objectName The <TT>objectName</TT> input parameter defines the target
    CIM Object whose referring Objects are to be returned. This is either a
    Class name or Instance name (model path).

    @param resultClass The <TT>resultClass</TT> input parameter, if not NULL,
    MUST be a valid CIM Class name. It acts as a filter on the returned set of
    Objects by mandating that each returned Object MUST be an Instance of this
    Class (or one of its subclasses), or this Class (or one of its subclasses).

    @param role The <TT>role</TT> input parameter, if not NULL, MUST be a valid
    CIMProperty name. It acts as a filter on the returned set of Objects by
    mandating that each returned Objects MUST refer to the target Object via a
    CIMProperty whose name matches the value of this parameter.

    @param includeQualifiers.  If the <TT>includeQualifiers</TT> input parameter
    is true, this specifies that all Qualifiers for each Object (including
    Qualifiers on the Object and on any returned Properties) MUST be included as
    <QUALIFIER> elements in the response.  If false no <QUALIFIER> elements are
    present in each returned Object.

    @param includeClassOrigin If the <TT>includeClassOrigin</TT> input parameter
    is true, this specifies that the CLASSORIGIN attribute MUST be present on
    all appropriate elements in each returned Object. If false, no CLASSORIGIN
    attributes are present in each returned Object.

    @param propertyList If the <TT>propertyList</TT> input parameter is not
    NULL, the members of the array define one or more CIMProperty names.  Each
    returned Object MUST NOT include elements for any Properties missing from
    this list. Note that if LocalOnly is specified as true (or DeepInheritance
    is specified as false) this acts as an additional filter on the set of
    Properties returned (for example, if CIMProperty A is included in the
    PropertyList but LocalOnly is set to true and A is not local to a returned
    Instance, then it will not be included in that Instance). If the
    PropertyList input parameter is an empty array this signifies that no
    Properties are included in each returned Object. If the PropertyList input
    parameter is NULL this specifies that all Properties (subject to the
    conditions expressed by the other parameters) are included in each returned
    Object.

    If the PropertyList contains duplicate elements, the Server MUST ignore the
    duplicates but otherwise process the request normally.  If the PropertyList
    contains elements which are invalid CIMProperty names for any target Object,
    the Server MUST ignore such entries but otherwise process the request
    normally.

    Clients SHOULD NOT explicitly specify properties in the PropertyList
    parameter unless they have specified a non-NULL value for the ResultClass
    parameter.

    @return If successful, the method returns zero or more CIM Classes or
    Instances meeting the requested criteria.  Since it is possible for CIM
    Objects from different hosts or namespaces to be associated, each returned
    Object includes location information.

    method, where the first applicable error in the list (starting with the
    first element of the list, and working down) is the error returned. Any
