/**

*
* This is the lowest abstraction that encapsulates the difference
* between reading inline annotations and external binding files.
*
*
* Because the former operates on a {@link Field} and {@link Method}
* while the latter operates on a "property", the methods defined
* on this interface takes both, and the callee gets to choose which
* to use.
*
*
* Most of the get method takes {@link Locatable}, which points to
* the place/context in which the annotation is read. The returned
* annotation also implements {@link Locatable} (so that it can
* point to the place where the annotation is placed), and its
* {@link Locatable#getUpstream()} will return the given
* {@link Locatable}.
*
*
*
* Errors found during reading annotations are reported through the error handler.
* A valid {@link ErrorHandler} must be registered before the {@link AnnotationReader}
* is used.
