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.
