getInputStream

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

Description copied from interface: Storage

Returns an InputStream that can be used to read the stored data. The input stream should be closed by the caller when it is no longer needed.

Note: The stream should NOT be wrapped in a BufferedInputStream by the caller. If the implementing Storage creates a stream which would benefit from being buffered it is the Storage's responsibility to wrap it.

Specified by:

getInputStream in interface Storage

Returns:

an InputStream for reading the stored data.

Throws:

java.io.IOException - if an I/O error occurs.
