    public final class CountingOutputStream

extends java.io.FilterOutputStream

This class is a FilterOutputStream that counts the number of bytes written to the lower-level OutputStream.

### CountingOutputStream

    public CountingOutputStream(java.io.OutputStream out)

Method Detail

### write

    public void write(int b)
               throws java.io.IOException

  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 `java.io.FilterOutputStream`
  Parameters:
    `b` - the `byte`.
  Throws:
    `java.io.IOException` - if an I/O error occurs.

### write

    public void write(byte[] b)
               throws java.io.IOException

  Writes `b.length` bytes to this output stream.

  The `write` method of `FilterOutputStream` calls its `write` method of three arguments with the arguments `b`, `0`, and `b.length`.

  Note that this method does not call the one-argument `write` method of its underlying stream with the single argument `b`.

  Overrides:
    `write` in class `java.io.FilterOutputStream`
  Parameters:
    `b` - the data to be written.
  Throws:
    `java.io.IOException` - if an I/O error occurs.
  See Also:
    `FilterOutputStream.write(byte[], int, int)`

### write

    public void write(byte[] b,
                      int off,
                      int len)
               throws java.io.IOException

  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 input stream with the same arguments. Subclasses of `FilterOutputStream` should provide a more efficient implementation of this method.

  Overrides:
    `write` in class `java.io.FilterOutputStream`
  Parameters:
    `b` - the data.
    `off` - the start offset in the data.
    `len` - the number of bytes to write.
  Throws:
    `java.io.IOException` - if an I/O error occurs.
  See Also:
    `FilterOutputStream.write(int)`

### getByteCount

    public long getByteCount()

  Get the number of bytes passed through this stream (so far).

  Returns:
    the number of written bytes so far.
