-/**
- * This is the common superclass of all standard classes that filter
- * input. It acts as a layer on top of an underlying <code>InputStream</code>
- * and simply redirects calls made to it to the subordinate InputStream
- * instead. Subclasses of this class perform additional filtering
- * functions in addition to simply redirecting the call.
- * <p>
- * This class is not abstract. However, since it only redirects calls
- * to a subordinate <code>InputStream</code> without adding any functionality
- * on top of it, this class should not be used directly. Instead, various
- * subclasses of this class should be used. This is enforced with a
- * protected constructor. Do not try to hack around it.
- * <p>
- * When creating a subclass of <code>FilterInputStream</code>, override the
- * appropriate methods to implement the desired filtering. However, note
- * that the <code>read(byte[])</code> method does not need to be overridden
- * as this class redirects calls to that method to
- * <code>read(byte[], int, int)</code> instead of to the subordinate
- * <code>InputStream read(byte[])</code> method.
