# Bio::DB::SeqFeature::NormalizedTableFeatureI(3pm)

## NAME

Bio::DB::SeqFeature::NormalizedTableFeatureI -- Interface for normalized features whose hierarchy is stored in a table

## SYNOPSIS

none

## DESCRIPTION

This is an extremely simple interface that contains a single method, **subfeatures\_are\_stored\_in\_a\_table()**. This method returns a true value.

Bio::DB::SeqFeature::Store feature classes will inherit this interface to flag that in addition to being able to store features in a normalized way, they will use the Bio::DB::SeqFeature::Store database to record their parent/child relationships. A class that inherits from NormalizedTableFeatureI will also inherit from NormalizedFeatureI, as the first is a subclass of the second.

## BUGS

None, but the whole class design might be flawed.
