Subject [jira] Created: (IO-92) new ThresholdingOutputStream implementation
Date Mon, 11 Sep 2006 07:41:22 GMT
new ThresholdingOutputStream implementation
-------------------------------------------

                 Key: IO-92
                 URL: http://issues.apache.org/jira/browse/IO-92
             Project: Commons IO
          Issue Type: Improvement
          Components: Streams/Writers
    Affects Versions: 1.2
         Environment: Windows XP SP2, jdk 1.5
            Reporter: Michele Mazzucco


I've extended the ThresholdingOutputStream class with a new class which
behaves different from DeferredFileOutputStream:
- when the stream is closed, the content stored in memory is *always* flushed to disk (in
DeferredFileOutputStream, instead, if the treshold
is not reached data is lost)
- DeferredFileOutputStream maintains data in memory only until the treshold value has been
reached, then it immediately writes every byte
to disk. This new implementation, instead, caches treshold bytes in memory, and every time
that value is reached (that is, treshold, 2 * threshold, etc), it flushes data to disk. In
other words it acts as a cache.
- It implements the java.io.DataOutput interface, that is, it provides utility methods to
write all primitive types (e.g. short, byte, char, int, float, long, double and String in
different formats)
