NAME

HTML::FormEngine::DBSQL::DtHandler - DBMS datatype handlers

GENERAL INFORMATION ABOUT DATATYPE HANDLERS

To every handler is given:

  • the object reference

  • a reference to the fields form configuration hash

  • a reference to a hash which contains information about the column, the information is extracted with the help of DBIs column_info method, read the documentation of DBI for more information.

The handler then modifies the fields configuration hash and can use information out of the column information hash (which he mustn't modify!).

Which handler is called for which datatype is configured by the skin. The default skin is HTML::FormEngine::DBSQL::SkinClassic.
