- - ### Constructor Detail

    - #### AbstractFbWireInputBlob

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

  - ### Method Detail

    - #### 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 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`.

      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.
