Method Detail- 
getBlobIdpublic final long getBlobId() - Returns:
- The Firebird blob id
 
 - 
isOutputpublic final boolean isOutput() - Returns:
- trueif this is an output blob (write only),- falseif this is an input blob (read only)
 
 - 
putSegmentpublic final void putSegment(byte[] segment) throws java.sql.SQLExceptionDescription copied from interface:FbBlobWrites 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:
- java.sql.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.
