Method Detail

getStream

public InputStream getStream()

isPersistent

public boolean isPersistent()

Description copied from interface: Blob

Checks whether this blob is persistent. (i.e. if Blob.getStream() can be successfully called several times).

Returns:

true if persistent, false otherwise

persist

public Blob persist()
             throws IOException

Description copied from interface: Blob

Persist this stream so that Blob.getStream() method can be called successfully several times. The persistence is done in a temporary file or in memory - this is up to the implementation.

Blobs that are already persistent return themselves.

Persistence should update the internal structure of the Blob to make it persistent whenever possible and hence return itself whenever possible. This behavior cannot be guaranteed by every implementation however.

Returns:

a persistent version of the blob

Throws:

IOException
