BlobDataCell example


The documentation on the BlobDataCell is relatively sparse, so I would like to confirm with you my approach:

I want to put long strings into a cell and was thinking of using the BlobDataCells to hold them. Since this class is abstract I guess I will have to implement my own DataType for this. Is this correct?

And I would just extend the DataValue interface and MyDataCell class that I have to create in order to generate my own data type with BlobDataCell to make this work?

Thanks for any comment, examples, help… :wink:



From my experience it is a simple as implementing any other data type: just subclass from BlobDataCell instead of DataCell and the rest works automatically. So yes, you need to write your own data type, the existing types cannot be converted blobs by any other means.
