927 * ObjectActor ID for which it desires to evaluate an expression. The
928 * Debugger.Object pointed at by the actor ID is bound such that it is
929 * available during expression evaluation (evalInGlobalWithBindings()).
930 *
931 * Example:
932 * _self['foobar'] = 'test'
933 * where |_self| refers to the desired object.
934 *
935 * The |frameActor| property allows the Web Console client to provide the
936 * frame actor ID, such that the expression can be evaluated in the
937 * user-selected stack frame.
938 *
939 * For the above to work we need the debugger and the Web Console to share
940 * a connection, otherwise the Web Console actor will not find the frame
941 * actor.
942 *
943 * The Debugger.Frame comes from the jsdebugger's Debugger instance, which
944 * is different from the Web Console's Debugger instance. This means that
945 * for evaluation to work, we need to create a new instance for the jsterm
946 * helpers - they need to be Debugger.Objects coming from the jsdebugger's
947 * Debugger instance.
948 *
949 * When |bindObjectActor| is used objects can come from different iframes,
950 * from different domains. To avoid permission-related errors when objects
951 * come from a different window, we also determine the object's own global,
952 * such that evaluation happens in the context of that global. This means that
953 * evaluation will happen in the object's iframe, rather than the top level
954 * window.
955 *
956 * @param string aString
957 * String to evaluate.
958 * @param object [aOptions]
959 * Options for evaluation:
960 * - bindObjectActor: the ObjectActor ID to use for evaluation.
961 * |evalWithBindings()| will be called with one additional binding:
962 * |_self| which will point to the Debugger.Object of the given
963 * ObjectActor.
964 * - frameActor: the FrameActor ID to use for evaluation. The given
965 * debugger frame is used for evaluation, instead of the global window.
966 * @return object
967 * An object that holds the following properties:
968 * - dbg: the debugger where the string was evaluated.
969 * - frame: (optional) the frame where the string was evaluated.
970 * - window: the Debugger.Object for the global where the string was
971 * evaluated.
