             throws IOException

  Specified by:
    `read` in class `InputStream`
  Throws:
    `IOException`
  See Also:
    `InputStream.read()`

### read

    public int read(byte[] b,
                    int off,
                    int len)
             throws IOException

  Overrides:
    `read` in class `InputStream`
  Throws:
    `IOException`
  See Also:
    `InputStream.read(byte[], int, int)`

### read

    public int read(byte[] b)
             throws IOException

  Overrides:
    `read` in class `InputStream`
  Throws:
    `IOException`
  See Also:
    `InputStream.read(byte[])`

### close

    public void close()
               throws IOException

    `InputStream.close()`

### getHash

    public byte[] getHash()

  Get the hash of the content read by this stream. This method will return null if the stream has not yet been closed.

  Returns:
    the hash of the contents as a byte array, or null if the stream has not yet been closed

### getHashAsHexString

    public String getHashAsHexString()

  Get the string representation of the binary hash of the content read by this stream. This method will return null if the stream has not yet been closed.

  Returns:
    the hex-encoded representation of the binary hash of the contents, or null if the stream has not yet been closed
