| 37 | * We have five kinds of classes: |
| 38 | * a) Top level classes |
| 39 | * b) Nested classes (static member classes) |
| 40 | * c) Inner classes (non-static member classes) |
| 41 | * d) Local classes (named classes declared within a method) |
| 42 | * e) Anonymous classes |
| 43 | * |
| 44 | * Each one can be within a package or not. |
| 45 | * Kinds b-e can/must be within kinds a-e. |
| 46 | * This gives us a three dimensional space: |
| 47 | * 1. dimension: b-e |
| 48 | * 2. dimension: a-e |
| 49 | * 3. dimension: packages |
| 50 | * |
| 51 | * We make a two dimensional matrix of (b-e)x(a-e) and change the |
| 52 | * package configuration on that: |
| 53 | * |
| 54 | * b c d e |
| 55 | * a x x x x |
| 56 | * b x x x x |
| 57 | * c o x x x where o means "not legal" |
