=head1 NAME
Rose::DB::Object::Metadata::Column::Bitfield - Bitfield column metadata.
=head1 SYNOPSIS
use Rose::DB::Object::Metadata::Column::Bitfield;
$col = Rose::DB::Object::Metadata::Column::Bitfield->new(...);
$col->make_methods(...);
...
=head1 DESCRIPTION
Objects of this class store and manipulate metadata for bitfield columns in a database. Column metadata objects store information about columns (data type, size, etc.) and are responsible for parsing, formatting, and 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.
B<Important note:> if you are using MySQL 5.0.3 or later, you I<must> L<allow inline column values|Rose::DB::Object::Metadata/allow_inline_column_values> in any L<Rose::DB::Object>-derived class that has one or more bitfield columns. (That is, columns that use the C<BIT> data type.) This requirement may be relaxed in the future.
=head1 METHOD MAP

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<bits [INT]>
Get or set the number of bits in the column.
=item B<parse_value DB, VALUE>
Convert VALUE to the equivalent C<Bit::Vector> object. The return value of the column object's C<bits()> method is used to determine the length of the bitfield in bits. DB is a L<Rose::DB> object that is used as part of the parsing process. Both arguments are required.
=item B<type>
Returns "bitfield".
