Class HashingOutputStream

    • Method Detail

      • write

        public void write​(int b)
                   throws IOException
        Description copied from class: java.io.FilterOutputStream
        Writes the specified byte to this output stream.

        The write method of FilterOutputStream calls the write method of its underlying output stream, that is, it performs out.write(b).

        Implements the abstract write method of OutputStream.

        Overrides:
        write in class FilterOutputStream
        Parameters:
        b - the byte.
        Throws:
        IOException - if an I/O error occurs.
      • write

        public void write​(byte[] bytes,
                          int off,
                          int len)
                   throws IOException
        Description copied from class: java.io.FilterOutputStream
        Writes len bytes from the specified byte array starting at offset off to this output stream.

        The write method of FilterOutputStream calls the write method of one argument on each byte to output.

        Note that this method does not call the write method of its underlying output stream with the same arguments. Subclasses of FilterOutputStream should provide a more efficient implementation of this method.

        Overrides:
        write in class FilterOutputStream
        Parameters:
        bytes - the data.
        off - the start offset in the data.
        len - the number of bytes to write.
        Throws:
        IOException - if an I/O error occurs.

      • hash

        public HashCode hash()
        Returns the HashCode based on the data written to this stream. The result is unspecified if this method is called more than once on the same instance.
