-/**
- * This is the common superclass of all standard classes that filter
- * input. It acts as a layer on top of an underlying <code>Reader</code>
- * and simply redirects calls made to it to the subordinate Reader
- * instead. Subclasses of this class perform additional filtering
- * functions in addition to simply redirecting the call.
- * <p>
- * When creating a subclass of <code>FilterReader</code>, override the
- * appropriate methods to implement the desired filtering. However, note
- * that the <code>read(char[])</code> method does not need to be overridden
- * as this class redirects calls to that method to
- * <code>read(yte[], int, int)</code> instead of to the subordinate
- * <code>Reader} read(yte[])</code> method.
