AbstractFbWireInputBlob

protected AbstractFbWireInputBlob(FbWireDatabase database,
 FbWireTransaction transaction,
 BlobParameterBuffer blobParameterBuffer,
 long blobId)

Method Details

getBlobId

public final long getBlobId()

Returns:

The Firebird blob id

isOutput

public final boolean isOutput()

Returns:

true if this is an output blob (write only), false if this is an input blob (read only)

putSegment

public final 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.

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.
