public class InputStreamResource extends AbstractResource
Resource
implementation for a given InputStream
.
Should only be used if no other specific Resource
implementation
is applicable. In particular, prefer ByteArrayResource
or any of the
file-based Resource
implementations where possible.
In contrast to other Resource
implementations, this is a descriptor
for an already opened resource - therefore returning true
from
isOpen()
. Do not use an InputStreamResource
if you need to
keep the resource descriptor somewhere, or if you need to read from a stream
multiple times.
