Method Detail

getStream

public java.io.InputStream getStream()
                              throws java.io.IOException

Description copied from interface: ContentStream

Get an open stream. You are responsible for closing it. Consider using something like:

   InputStream stream = stream.getStream();
   try {
     // use the stream...
   }
   finally {
     IOUtils.closeQuietly(stream);
   }
  

Only the first call to getStream() or getReader() is guaranteed to work. The runtime behavior for additional calls is undefined. Note: you must call getStream() or getReader() before the attributes (name, contentType, etc) are guaranteed to be set. Streams may be lazy loaded only when this method is called.

Throws:

java.io.IOException

getReader

public java.io.Reader getReader()
                         throws java.io.IOException

If an charset is defined (by the contentType) use that, otherwise use a file reader

Specified by:

getReader in interface ContentStream

Overrides:

getReader in class ContentStreamBase

Throws:

java.io.IOException
