DigestOutputStream (Java SE 21 & JDK 21)

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

A transparent stream that updates the associated message digest using the bits going through the stream.

To complete the message digest computation, call one of the digest methods on the associated message digest after your calls to one of this digest output stream's write methods.

It is possible to turn this stream on or off (see on). When it is on, a call to one of the write methods results in an update on the message digest. But when it is off, the message digest is not updated. The default is for the stream to be on.

Since:

1.2

See Also:

• MessageDigest
• DigestInputStream

• Field Summary

  Fields

  The message digest associated with this stream.

• Constructor Summary

  Constructors

  Creates a digest output stream, using the specified output stream and message digest.

• Method Summary

  Returns the message digest associated with this stream.

  void

  Turns the digest function on or off.

  void

  Associates the specified message digest with this stream.

  Prints a string representation of this digest output stream and its associated message digest object.

  void

  write(byte[] b, int off, int len)

  Updates the message digest (if the digest function is on) using the specified subarray, and in any case writes the subarray to the output stream.

  void

  Updates the message digest (if the digest function is on) using the specified byte, and in any case writes the byte to the output stream.

• Field Details
  • digest

    The message digest associated with this stream.

• Constructor Details
  • DigestOutputStream

    Creates a digest output stream, using the specified output stream and message digest.

    Parameters:

    stream - the output stream.

    digest - the message digest to associate with this stream.

• Method Details
  • getMessageDigest

    Returns the message digest associated with this stream.

    Returns:

    the message digest associated with this stream.

    See Also:

    • setMessageDigest(java.security.MessageDigest)

  • setMessageDigest

    Associates the specified message digest with this stream.

    Parameters:

    digest - the message digest to be associated with this stream.

    See Also:

    • getMessageDigest()

  • write

    Updates the message digest (if the digest function is on) using the specified byte, and in any case writes the byte to the output stream. That is, if the digest function is on (see

    on

    ), this method calls

    update

    on the message digest associated with this stream, passing it the byte

    b

    . This method then writes the byte to the output stream, blocking until the byte is actually written.

    Overrides:

    write in class FilterOutputStream

    Parameters:

    b - the byte to be used for updating and writing to the output stream.

    Throws:

    IOException - if an I/O error occurs.

    See Also:

    • MessageDigest.update(byte)

  • write public void write(byte[] b, int off, int len)

    throws

    IOException

    Updates the message digest (if the digest function is on) using the specified subarray, and in any case writes the subarray to the output stream. That is, if the digest function is on (see

    on

    ), this method calls

    update

    on the message digest associated with this stream, passing it the subarray specifications. This method then writes the subarray bytes to the output stream, blocking until the bytes are actually written.

    Overrides:

    write in class FilterOutputStream

    Parameters:

    b - the array containing the subarray to be used for updating and writing to the output stream.

    off - the offset into b of the first byte to be updated and written.

    len - the number of bytes of data to be updated and written from b, starting at offset off.

    Throws:

    IOException - if an I/O error occurs.

    See Also:

    • MessageDigest.update(byte[], int, int)

  • on

    public void on(boolean on)

    Turns the digest function on or off. The default is on. When it is on, a call to one of the write methods results in an update on the message digest. But when it is off, the message digest is not updated.

    Parameters:

    on - true to turn the digest function on, false to turn it off.

  • toString

    Prints a string representation of this digest output stream and its associated message digest object.

    Overrides:

    toString in class Object

    Returns:

    a string representation of the object.
