InputStream readOnce() throws IOException
InputStream
that consumes the content of this data handler. This method is
similar to DataHandler.getInputStream()
except that it can be invoked only once. If
the content has not been buffered yet, then the implementation may choose to enable streaming
of the content.
The implementation ensures that after the returned input steam is consumed, the data handler
will be in the same state as after a call to purgeDataSource()
.
