      • readUnsignedInt

        public long readUnsignedInt()
                     throws java.io.IOException
        Read an unsigned integer from the contained input stream.
        Returns:
        the next four bytes of this input stream, interpreted as an unsigned 32-bit integer
        Throws:
        java.io.IOException - if an I/O error occurs
        java.io.EOFException - if this input stream reaches the end before reading four bytes

      • readUnsigned3ByteInt

        public int readUnsigned3ByteInt()
                         throws java.io.IOException
        Read an unsigned integer from the contained input stream.
        Returns:
        the next three bytes of this input stream, interpreted as an unsigned 24-bit integer
        Throws:
        java.io.IOException - if an I/O error occurs
        java.io.EOFException - if this input stream reaches the end before reading three bytes

      • skipFully

        public void skipFully​(long n)
               throws java.io.IOException
        Skips over and discards n bytes of data from the input stream. This method attempts to fully skip the number of bytes specified.
        Parameters:
        n - the number of bytes to be skipped
        Throws:
        java.io.IOException - if an I/O error occurs
        java.io.EOFException - if this input stream reaches the end before skipping the given number of bytes
