    37  * infer an enclosing method and/or class.

    39  * <p>A Scope does not itself contain the details of the elements corresponding

    40  * to the parameters, methods and fields of the methods and classes containing

    41  * its position. However, these elements can be determined from the enclosing

    42  * elements.

    44  * <p>Scopes may be contained in an enclosing scope. The outermost scope contains

    45  * those elements available via "star import" declarations; the scope within that

    46  * contains the top level elements of the compilation unit, including any named

    47  * imports.
