Constructor Detail

BinaryBlob

public BinaryBlob(Binary binary,
                  String key,
                  String filename,
                  String mimeType,
                  String encoding,
                  String digest,
                  long length)

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 AbstractBlob

Returns:

the data length or -1 if not known

getStream

public InputStream getStream()
                      throws IOException

Description copied from interface: Blob

Gets an InputStream for the data of this blob.

The contract of Blob is that this method can be called several times and will correctly return a new InputStream each time. In other words, several reads of the Blob can be done.

Like all InputStream, the result must be closed when done with it to avoid resource leaks.

Specified by:

getStream in interface Blob

Returns:

the stream

Throws:

IOException

getBinary

public Binary getBinary()

Gets the Binary attached to this blob.

Returns:

the binary

Since:

5.9.4

getDigestAlgorithm

public String getDigestAlgorithm()

Specified by:

getDigestAlgorithm in interface Blob

Overrides:

getDigestAlgorithm in class AbstractBlob

getDigest

public String getDigest()

Specified by:

getDigest in interface Blob

Overrides:

getDigest in class AbstractBlob

getKey

public String getKey()

Description copied from interface: ManagedBlob

Gets the stored representation of this blob.

Specified by:

getKey in interface ManagedBlob

Returns:

the stored representation

getProviderId

public String getProviderId()

Description copied from interface: ManagedBlob

Gets the id of the BlobProvider managing this blob.

Specified by:

getProviderId in interface ManagedBlob

Returns:

the blob provider id

getFile

public File getFile()

Description copied from interface: Blob

If this blob is backed by an actual file, returns it.

The returned file may be short-lived (temporary), so should be used immediately.

Specified by:

getFile in interface Blob

Overrides:

getFile in class AbstractBlob

Returns:

a file, or null if the blob is not backed by a file

equalsStream

protected boolean equalsStream(Blob blob)

Overrides:

equalsStream in class AbstractBlob
