## Class SkipShieldingInputStream

- java.lang.Object

- All Implemented Interfaces:
    Closeable, AutoCloseable

      public class SkipShieldingInputStream
      extends FilterInputStream

  A wrapper that overwrites `skip(long)` and delegates to `FilterInputStream.read()` instead.

  Some implementations of `InputStream` implement `InputStream.skip(long)` in a way that throws an exception if the stream is not seekable - `System.in` is known to behave that way. For such a stream it is impossible to invoke skip at all and you have to read from the stream (and discard the data read) instead. Skipping is potentially much faster than reading so we do want to invoke `skip` when possible. We provide this class so you can wrap your own `InputStream` in it if you encounter problems with `skip` throwing an exception.
