public DigestOutputStream (OutputStream stream, MessageDigest digest)

Public Methods

public MessageDigest getMessageDigest ()

Returns the MessageDigest which the receiver uses when computing the hash.

Returns
  • MessageDigest the digest the receiver uses when computing the hash.

public void on (boolean on)

Enables or disables the digest function (default is on).

public void setMessageDigest (MessageDigest digest)

Sets the MessageDigest which the receiver will use when computing the hash.

Parameters
digest MessageDigest the digest to use when computing the hash.
See Also

public String toString ()

Returns a string containing a concise, human-readable description of the receiver.

Returns
  • String a printable representation for the receiver.

public void write (int b)

Writes the specified byte oneByte to this FilterOutputStream. Only the low order byte of oneByte is written. This implementation writes the byte to the target OutputStream.

Parameters
b the byte to be written
Throws
IOException

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

Writes count bytes from the byte array buffer starting at offset to this FilterOutputStream. This implementation writes the buffer to the target OutputStream.

Parameters
b the buffer to be written
off offset in buffer to get bytes
len number of bytes in buffer to write
Throws
IOException
