TDataSet.CreateBlobStream function
Create blob stream.
Declaration
function CreateBlobStream(Field: TField; Mode: TBlobStreamMode)
: TStream; virtualArguments
Field | BLOB Field for which data should be fetched/written. |
Mode | Mode: read or write. |
Function result
Stream with (for) blob data.
Description
CreateBlobStream is not intended for use by application programmers.
It creates a stream object which can be used to read or write data from a blob field.
Instead, application programmers should use the
LoadFromStream and
SaveToStream methods when reading and writing data from/to BLOB fields.
Which operation must be performed on the stream is indicated in the
Mode parameter,
and the
Field parameter contains the field whose data should be read.
The caller is responsible for freeing the stream created by this function.See also
