| 35 * Interface for determining locally available program elements, such as | |
| 36 * local variables and imports. | |
| 37 * Upon creation, a Scope is associated with a given program position; | |
| 38 * for example, a {@linkplain Tree tree node}. This position may be used to | |
| 39 * infer an enclosing method and/or class. | |
| 40 * | |
| 41 * <p>A Scope does not itself contain the details of the elements corresponding | |
| 42 * to the parameters, methods and fields of the methods and classes containing | |
| 43 * its position. However, these elements can be determined from the enclosing | |
| 44 * elements. | |
| 45 * | |
| 46 * <p>Scopes may be contained in an enclosing scope. The outermost scope contains | |
| 47 * those elements available via "star import" declarations; the scope within that | |
| 48 * contains the top level elements of the compilation unit, including any named | |
| 49 * imports. | |
