 org.apache.commons.io.output.CountingOutputStream
| CountingOutputStream | | public class CountingOutputStream extends ProxyOutputStream (Code) | | A decorating output stream that counts the number of bytes that have passed
through the stream so far.
A typical use case would be during debugging, to ensure that data is being
written as expected.

| Method Summary | |
| public synchronized long | getByteCount()
The number of bytes that have passed through this stream. | | public synchronized int | getCount()
The number of bytes that have passed through this stream. | | public synchronized long | resetByteCount()
Set the byte count back to 0. | | public synchronized int | resetCount()
Set the byte count back to 0. | | public void | write(byte[] b)
Writes the contents of the specified byte array to this output stream
keeping count of the number of bytes written. | | public void | write(byte[] b, int off, int len)
Writes a portion of the specified byte array to this output stream
keeping count of the number of bytes written. | | public void | write(int b)
Writes a single byte to the output stream adding to the count of the
number of bytes written. |
| CountingOutputStream | | public CountingOutputStream(OutputStream out)(Code) | | Constructs a new CountingOutputStream.
Parameters:
out - the OutputStream to write to |
| getByteCount | | public synchronized long getByteCount()(Code) | | The number of bytes that have passed through this stream.
NOTE: This method is an alternative for getCount().
It was added because that method returns an integer which will
result in incorrect count for files over 2GB.
the number of bytes accumulated
since:
Commons IO 1.3 |
| getCount | | public synchronized int getCount()(Code) | | The number of bytes that have passed through this stream.
NOTE: From v1.3 this method throws an ArithmeticException if the
count is greater than can be expressed by an int.
See
CountingOutputStream.getByteCount() for a method using a long.
the number of bytes accumulated
throws:
ArithmeticException - if the byte count is too large |
| resetByteCount | | public synchronized long resetByteCount()(Code) | | Set the byte count back to 0.
NOTE: This method is an alternative for resetCount().
It was added because that method returns an integer which will
result in incorrect count for files over 2GB.
the count previous to resetting
since:
Commons IO 1.3 |
| resetCount | | public synchronized int resetCount()(Code) | | Set the byte count back to 0.
NOTE: From v1.3 this method throws an ArithmeticException if the
count is greater than can be expressed by an int.
See
CountingOutputStream.resetByteCount() for a method using a long.
the count previous to resetting
throws:
ArithmeticException - if the byte count is too large |
| write | | public void write(byte[] b, int off, int len) throws IOException(Code) | | Writes a portion of the specified byte array to this output stream
keeping count of the number of bytes written.
Parameters:
b - the bytes to write, not null
Parameters:
off - the start offset in the buffer
Parameters:
len - the maximum number of bytes to write
throws:
IOException - if an I/O error occurs
