This component automatically removes ``heavy-weight'' columns. To be specific, columns of type "text", "ntext", "blob", "clob", or "bytea". You may use the "remove_column" key in the column info to specify directly whether or not to remove the column automatically. See ``NOTE'' in DBIx::Class::Helper::ResultSet for a nice way to apply it to your entire schema.




returns true if a column should be fetched or not. This fetches a column if it is not of type "text", "ntext", "blob", "clob", or "bytea" or the "remove_column" is set to true. If you only wanted to explicitly state which columns to remove you might override this method like this:

 sub _should_column_fetch {
    my ( $self, $column ) = @_;
    my $info = $self->column_info($column);
    return !defined $info->{remove_column} || $info->{remove_column};


simply returns a list of columns that are fetchable.
