holdTempFile

public void holdTempFile()

releaseTempFileHold

public void releaseTempFileHold()

registerCallback

public void registerCallback(CachedWriterCallback cb)

deregisterCallback

public void deregisterCallback(CachedWriterCallback cb)

getCallbacks

public List<CachedWriterCallback> getCallbacks()

doFlush

protected void doFlush()
                throws IOException
Perform any actions required on stream flush (freeze headers, reset output stream ... etc.)

Throws:
IOException

flush

public void flush()
           throws IOException
Specified by:
flush in interface Flushable
Specified by:
flush in class Writer
Throws:
IOException

doClose

protected void doClose()
                throws IOException
Perform any actions required on stream closure (handle response etc.)

Throws:
IOException

postClose

protected void postClose()
                  throws IOException
Perform any actions required after stream closure (close the other related stream etc.)

Throws:
IOException

lockOutputStream

public void lockOutputStream()
                      throws IOException
Locks the output stream to prevent additional writes, but maintains a pointer to it so an InputStream can be obtained

Throws:
IOException

close

public void close()
           throws IOException
Specified by:
close in interface Closeable
Specified by:
close in class Writer
Throws:
IOException

equals

public boolean equals(Object obj)
Overrides:

resetOut

public void resetOut(Writer out,

Replace the original stream with the new one, optionally copying the content of the old one into the new one. When with Attachment, needs to replace the xml writer stream with the stream used by AttachmentSerializer or copy the cached output stream to the "real" output stream, i.e. onto the wire.

Parameters:
out - the new output stream
copyOldContent - flag indicating if the old content should be copied
