Constructor Detail

SQLBlob

public SQLBlob(Binary binary,
       String filename,
       String mimeType,
       String encoding,
       String digest)

Method Detail

getLength

public long getLength()

Description copied from interface: Blob

Gets the data length in bytes if known.

Specified by:

getLength in interface Blob

Overrides:

getLength in class StreamBlob

Returns:

the data length or -1 if not known

getStream

public InputStream getStream()
                      throws IOException

Specified by:

getStream in interface Blob

Throws:

IOException

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).

Specified by:

isPersistent in interface Blob

Returns:

true if persistent, false otherwise

persist

public Blob persist()

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.

Specified by:

persist in interface Blob

Returns:

a persistent version of the blob

getBinary

public Binary getBinary()

getDigest

public String getDigest()

Specified by:

getDigest in interface Blob

Overrides:

getDigest in class DefaultStreamBlob
