aoqi@0 | 38 | * <p> |
aoqi@0 | 39 | * This is the lowest abstraction that encapsulates the difference |
aoqi@0 | 40 | * between reading inline annotations and external binding files. |
aoqi@0 | 41 | * |
aoqi@0 | 42 | * <p> |
aoqi@0 | 43 | * Because the former operates on a {@link Field} and {@link Method} |
aoqi@0 | 44 | * while the latter operates on a "property", the methods defined |
aoqi@0 | 45 | * on this interface takes both, and the callee gets to choose which |
aoqi@0 | 46 | * to use. |
aoqi@0 | 47 | * |
aoqi@0 | 48 | * <p> |
aoqi@0 | 49 | * Most of the get method takes {@link Locatable}, which points to |
aoqi@0 | 50 | * the place/context in which the annotation is read. The returned |
aoqi@0 | 51 | * annotation also implements {@link Locatable} (so that it can |
aoqi@0 | 52 | * point to the place where the annotation is placed), and its |
aoqi@0 | 53 | * {@link Locatable#getUpstream()} will return the given |
aoqi@0 | 54 | * {@link Locatable}. |
aoqi@0 | 55 | * |
aoqi@0 | 56 | * |
aoqi@0 | 57 | * <p> |
aoqi@0 | 58 | * Errors found during reading annotations are reported through the error handler. |
aoqi@0 | 59 | * A valid {@link ErrorHandler} must be registered before the {@link AnnotationReader} |
aoqi@0 | 60 | * is used. |
