aoqi@0 | 80 | * Compile all the classes in a class spec, and put them on the classpath. |

aoqi@0 | 82 | * The spec is the specification for a nest of classes, using the following notation |
aoqi@0 | 83 | * A, B represent abstract classes |
aoqi@0 | 84 | * C represents a concrete class |
aoqi@0 | 85 | * I, J, K represent interfaces |
aoqi@0 | 86 | * Lowercase 'c' following a class means that the method m() is concrete |
aoqi@0 | 87 | * Lowercase 'a' following a class or interface means that the method m() is abstract |
aoqi@0 | 88 | * Lowercase 'd' following an interface means that the method m() is default |
aoqi@0 | 89 | * A number 0, 1, or 2 following the lowercase letter indicates the return type of that method |
aoqi@0 | 90 | * 0 = Object, 1 = Number, 2 = Integer (these form an inheritance chain so bridges are generated) |
aoqi@0 | 91 | * A classes supertypes follow its method spec, in parentheses |
aoqi@0 | 92 | * Examples: |
aoqi@0 | 93 | * C(Ia0, Jd0) -- C extends I and J, I has abstract m()Object, J has default m()Object |
aoqi@0 | 94 | * Cc1(Ia0) -- C has concrete m()Number, extends I with abstract m()Object |
aoqi@0 | 95 | * If a type must appear multiple times, its full spec must be in the first occurrence |
aoqi@0 | 96 | * Example: |
aoqi@0 | 97 | * C(I(Kd0), J(K)) |
