aoqi@0 | 35 | * Designates that a field, return value, argument, or a variable is supposed |
aoqi@0 | 36 | * to be an {@link String#intern() interned} string. |
aoqi@0 | 37 | * |
aoqi@0 | 38 | * <p> |
aoqi@0 | 39 | * In many places in the istack, we assume Strings to be interned for |
aoqi@0 | 40 | * the performance reason. Similarly, In many other places, we don't |
aoqi@0 | 41 | * make such an assumption for the performance reason (because intern |
aoqi@0 | 42 | * isn't free.) |
aoqi@0 | 43 | * |
aoqi@0 | 44 | * <p> |
aoqi@0 | 45 | * Therefore, distinguishing which part is supposed to be interned and |
aoqi@0 | 46 | * which part is supposed to be not is important. This annotation |
aoqi@0 | 47 | * allows us to capture that in the code. |
