Interface BlobParameterBuffer

public interface BlobParameterBuffer

Instance of this interface represents a BLOB Parameter Buffer from the Firebird API documentation and specifies attributes for GDS.iscCreateBlob2(IscDbHandle, IscTrHandle, IscBlobHandle, BlobParameterBuffer) or GDS.iscOpenBlob2(IscDbHandle, IscTrHandle, IscBlobHandle, BlobParameterBuffer) 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 GDS.iscSeekBlob(IscBlobHandle, int, int) for more details).
