Constructor Detail

OutputStreamCounter

public OutputStreamCounter(java.io.OutputStream out)
Creates a new instance of OutputStreamCounter

Method Detail

close

public void close()
           throws java.io.IOException
Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

The close method of OutputStream does nothing.

Specified by:
close in interface java.io.Closeable
Overrides:
close in class java.io.OutputStream
Throws:
java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException
Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

The flush method of OutputStream does nothing.

Specified by:
flush in interface java.io.Flushable
Overrides:
flush in class java.io.OutputStream
Throws:
java.io.IOException - if an I/O error occurs.

write

public void write(byte[] b)
           throws java.io.IOException
Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).

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

write

public void write(int b)
           throws java.io.IOException
Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Subclasses of OutputStream must provide an implementation for this method.

Specified by:
write in class java.io.OutputStream
Parameters:
b - the byte.
Throws:
java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

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 general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Overrides:
write in class java.io.OutputStream
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. In particular, an IOException is thrown if the output stream is closed.

getCounter

public int getCounter()

resetCounter

public void resetCounter()
