Custom DataType handler

[Christian Domsch]

Hi all,

Yesterday, I wrote a quick plugin to display custom blob content of our application (we put zipped streams into a blob, so essentially it just unzippes the stream). Works like a charm and the API of Squirrel SQL is really nice.

Now, my problem is that the IDataTypeComponentFactory.matches(DialectType, int, String) method only allows to match for column type. That means all BLOB columns will now be handled by my plugin. Clearly, that will fail for columns not associated with our application.

Is there a way to have a more fine granular control? Or is there a way to have a fallback from my plugin to the normal DataTypeBlob class?

Thanks in advance,
Christian

Hi Christian,
On a quick read of the source, if you return null from your readResultSet method it should fall back to the default handling.
Of course the default handling for a Blob is not useful, however that should work.
