Constructor Detail

V11InputBlob

public V11InputBlob(FbWireDatabase database,
                    FbWireTransaction transaction,
                    BlobParameterBuffer blobParameterBuffer,
                    long blobId)
             throws java.sql.SQLException

Throws:

java.sql.SQLException

Method Detail

open

public void open()
          throws java.sql.SQLException

Description copied from interface: FbBlob

Opens an existing input blob, or creates an output blob.

Specified by:

open in interface FbBlob

Overrides:

open in class V10InputBlob

Throws:

java.sql.SQLException - If the blob is already open, this is a (closed) output blob and it already has a blobId, the transaction is not active, or a database connection error occurred

checkBlobOpen

protected void checkBlobOpen()
                      throws java.sql.SQLException

Description copied from class: AbstractFbBlob

Checks if the blob is open.

NOTE: Subclasses may perform additional side effects, like queuing a server-side open for a deferred open blob.

Overrides:

checkBlobOpen in class AbstractFbBlob

Throws:

java.sql.SQLException - when the blob is closed.

getBlobInfo

public byte[] getBlobInfo(byte[] requestItems,
                          int bufferLength)
                   throws java.sql.SQLException

Description copied from interface: FbBlob

Request blob info.

Specified by:

getBlobInfo in interface FbBlob

Overrides:

getBlobInfo in class AbstractFbWireBlob

Parameters:

requestItems - Array of info items to request

bufferLength - Response buffer length to use

Returns:

Response buffer

Throws:

java.sql.SQLException
