public class InputStreamResource
Resource
implementation for a given InputStream. Should only
be used if no 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 it if you need to keep the resource
descriptor somewhere, or if you need to read a stream multiple times.
