Description
Use TEasyBlobStream to access or modify the value of a BLOB field object. BLOB field objects are TBlobField objects and descendants of TBlobField such as TGraphicField and TMemoField. BLOB fields use BLOB streams to implement a lot of of their data access properties and methods.
TEasyBlobStream allows objects to write to or read from BLOB field data of any type by means of using the uniform stream interface.To use a BLOB stream, create an instance of TEasyBlobStream, use the methods of the stream to read or write the data, and then free the BLOB stream. Do not use the same instance of TEasyBlobStream to access data from more than one record. Instead, create a new TEasyBlobStream object every time you need to read or write BLOB data on a new record.
