- - ### Constructor Detail

    - #### V10OutputBlob

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

  - ### 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`
      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

    - #### putSegment

          public void putSegment(byte[] segment)
                          throws java.sql.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:
        `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.
