Class B2InputStreamExcerpt

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable

    public class B2InputStreamExcerpt
    extends java.io.InputStream
    B2InputStreamExcerpt is a stream that provides the contents of an underlying stream starting from the start'th byte and continuing up to and including the (start + length - 1)'th byte. It relies on skip() working and working efficiently. It does NOT support mark/reset. If it throws an exception at any point, its state becomes undefined and you should stop using it. THREAD-SAFETY: this class is NOT thread-safe on its own.
