=head1 NAME
Rose::DB::Object::Metadata::Column::Interval - Interval column metadata.
=head1 SYNOPSIS
  use Rose::DB::Object::Metadata::Column::Interval;
  $col = Rose::DB::Object::Metadata::Column::Interval->new(...);
  $col->make_methods(...);
  ...
=head1 DESCRIPTION
Objects of this class store and manipulate metadata for interval columns in a database.  Column metadata objects store information about columns (data type, size, etc.) and are responsible for creating object methods that manipulate column values.
This class inherits from L<Rose::DB::Object::Metadata::Column>. Inherited methods that are not overridden will not be documented a second time here.  See the L<Rose::DB::Object::Metadata::Column> documentation for more information.
=head1 METHOD MAP
=over 4
=item C<get_set>
L<Rose::DB::Object::MakeMethods::Generic>, L<date|Rose::DB::Object::MakeMethods::Time/interval>, ...
=item C<get>
L<Rose::DB::Object::MakeMethods::Time>, L<date|Rose::DB::Object::MakeMethods::Time/interval>, ...
=item C<get_set>
L<Rose::DB::Object::MakeMethods::Time>, L<date|Rose::DB::Object::MakeMethods::Time/interval>, ...
=back
See the L<Rose::DB::Object::Metadata::Column|Rose::DB::Object::Metadata::Column/"MAKING METHODS"> documentation for an explanation of this method map.
=head1 OBJECT METHODS
=over 4
=item B<end_of_month_mode MODE>
This mode determines how math is done on duration objects.  If defined, the C<end_of_month> setting for each L<DateTime::Duration> object created by this column will have its mode set to MODE.  Otherwise, the C<end_of_month> parameter will not be passed to the L<DateTime::Duration> constructor.
Valid modes are C<wrap>, C<limit>, and C<preserve>.  See the documentation for L<DateTime::Duration> for a full explanation.
=item B<parse_value DB, VALUE>
Convert VALUE to the equivalent L<DateTime::Duration> object.  VALUE maybe returned unmodified if it is a valid interval keyword or otherwise has special meaning to the underlying database.  DB is a L<Rose::DB> object that is used as part of the parsing process.  Both arguments are required.
=item B<scale [INT]>
Get or set the integer number of places past the decimal point preserved for fractional seconds.  Defaults to 0.
Returns "interval".
=item B<type>
Returns "interval".
