Bug 483157 - mozStorageStatementRow needs to use mozIStorageStatement API This makes our language helper use public API instead of calling SQLite directly, which centralizes some of our logic. r=asuth r=bent

 * An nsIRDFResource is an object that has unique identity in the 
 * RDF data model. The object's identity is determined by its URI.
[scriptable, uuid(fb9686a7-719a-49dc-9107-10dea5739341)]
interface nsIRDFResource : nsIRDFNode {
     * The single-byte string value of the resource.
     * @note THIS IS OBSOLETE. C++ should use GetValueConst and script
     *       should use .valueUTF8
    readonly attribute string Value;

     * The UTF-8 URI of the resource.
    readonly attribute AUTF8String ValueUTF8;

     * An unscriptable version used to avoid a string copy. Meant
     * for use as a performance optimization. The string is encoded
     * in UTF-8.
    [noscript] void GetValueConst([shared] out string aConstValue);

     * This method is called by the nsIRDFService after constructing
     * a resource object to initialize its URI. You would not normally
     * call this method directly
    void Init(in string uri);

     * Determine if the resource has the given URI.
    boolean EqualsString(in string aURI);

     * Retrieve the "delegate" object for this resource. A resource
     * may have several delegate objects, each of whose lifetimes is
     * bound to the life of the resource object.
     * This method will return the delegate for the given key after
     * QueryInterface()-ing it to the requested IID.
     * If no delegate exists for the specified key, this method will
     * attempt to create one using the component manager. Specifically,
     * it will combine aKey with the resource's URI scheme to produce
     * a ContractID as follows:
     *   component:/rdf/delegate-factory/[key]/[scheme]
     * This ContractID will be used to locate a factory using the
     * FindFactory() method of nsIComponentManager. If the nsIFactory
     * exists, it will be used to create a "delegate factory"; that
     * is, an object that supports nsIRDFDelegateFactory. The delegate
     * factory will be used to construct the delegate object.
    void GetDelegate(in string aKey, in nsIIDRef aIID,
                     [iid_is(aIID),retval] out nsQIResult aResult);

     * Force a delegate to be "unbound" from the resource.
     * Normally, a delegate object's lifetime will be identical to
     * that of the resource to which it is bound; this method allows a
     * delegate to unlink itself from an RDF resource prematurely.
    void ReleaseDelegate(in string aKey);
