Constructor Detail

V10OutputBlob

public V10OutputBlob(FbWireDatabase database,
                     FbWireTransaction transaction,
                     BlobParameterBuffer blobParameterBuffer)

Method Detail

open

public void open()
          throws SQLException

Description copied from interface: FbBlob

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

Specified by:

open in interface FbBlob

Throws:

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

putSegment

public void putSegment(byte[] segment)
                throws SQLException

Description copied from interface: FbBlob

Writes a segment of blob data.

Implementation must handle segment length exceeding FbBlob.getMaximumSegmentSize() by batching. TODO: reconsider and let caller handle that?

Passing a section that is length 0 will throw an SQLException.

Specified by:

putSegment in interface FbBlob

Parameters:

segment - Segment to write

Throws:

SQLException - If this is an input blob, the blob is closed, the transaction is not active, the segment is length 0 or longer than the maximum segment size, or a database connection error occurred.
