Interface BlobParameterBuffer

All Superinterfaces:

Iterable<Parameter>, ParameterBuffer

All Known Implementing Classes:

BlobParameterBufferImp

public interface BlobParameterBuffer
extends ParameterBuffer

Instance of this interface represents a BLOB Parameter Buffer from the Firebird API documentation and specifies attributes for FbDatabase.createBlobForOutput(org.firebirdsql.gds.ng.FbTransaction, BlobParameterBuffer) or FbDatabase.createBlobForInput(org.firebirdsql.gds.ng.FbTransaction, BlobParameterBuffer, long) operations.

Two features are available:

• Specifying the source and target BLOB types (server uses BLOB filters to perform the conversion)
• Specifying type of the BLOB - either segmented or stream. The only visible to user difference between segmented and stream BLOBs is the fact that "seek" operation is not defined for segmented BLOBs (see FbBlob.seek(int, org.firebirdsql.gds.ng.FbBlob.SeekMode) for more details).
