Example 2 with WriterOutputStream

use of org.kohsuke.stapler.framework.io.WriterOutputStream in project hudson-2.x by hudson.

     * @return
     *      if the file is still being written, this method writes the file
     *      until the last newline character and returns the offset to start
     *      the next write operation.
