/**
This class defines the set of methods implemented by an association 
provider.  A providers that derives from this class must implement all of 
the methods.  The minimal method implementation simply throws the 
NotSupported exception. The methods implemented match the association
operations defined for the client:
    <UL>
    <LI> referenceNames
    <LI> references
    <LI> associatorNames
    <LI> associators
    </UL>
Note that the major difference is that the attributes implemented are not exactly
the same as the attributes of the operations implemented for the client.

    /** Enumerates CIM Objects (Instances only) that are associated to a
        particular source CIM Object. Returns CIM Objects. NOTE: if the objects
        do not include the host and namespace information this information will
        be inserted by the CIMOM based on the name of the host in which the cimom
        resides and the namespace in the request.

        @param context Contains security and locale information relevant for the 
        lifetime of this operation.  

        @param objectName The ObjectName input parameter defines the source CIM 
        Object whose associated Objects are to be returned.  This may be either a 
        Class name or Instance name (CIMObjectpath).  
            
        @param associationClass The AssocClass input parameter, if not NULL, MUST 
        be a valid CIM Association Class name.  It acts as a filter on the 
        returned set of Objects by mandating that each returned Object MUST be 
        associated to the source Object via an Instance of this Class or one of 
        its subclasses.  
            
        @param resultClass If not NULL, this parameter MUST be a valid CIM class 
        name.  It act as a filter on the returned set of Objects by mandating that 
        each returned Object MUST be either an Instance of this Class (or one of 
        its subclasses).  
            
        @param role If not NULL, this parameter MUST be a valid Property name.  It 
        acts as a filter on the returned set of Objects by mandating that each 
        returned Object MUST be associated to the source Object via an Association 
        in which the source Object plays the specified role (i.e.  the name of the 
        Property in the Association Class that refers to the source Object MUST 
        match the value of this parameter).  
            
        @param resultRole If not NULL, this parameter MUST be a valid Property 
        name.  It acts as a filter on the returned set of Objects by mandating 
        that each returned Object MUST be associated to the source Object via an 
        Association in which the returned Object plays the specified role (i.e.  
        the name of the Property in the Association Class that refers to the 
        returned Object MUST match the value of this parameter).  
            
        @param includeQualifiers If 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 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 not NULL, the members of the array define one or 
        more roperty names.  Each returned Object MUST NOT include elements for 
        any Properties missing from this list.  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.  

    @param handler Asynchronously processes the results of this operation.

    @exception NotSupported Methods not all supported by the provider return this
    exception.
    @exception InvalidParameter If a parameter is not specified correctly.
