=head1 NAME

Rose::DB::Object::Metadata::Column::Boolean - Boolean column metadata.

=head1 SYNOPSIS

  use Rose::DB::Object::Metadata::Column::Boolean;

  $col = Rose::DB::Object::Metadata::Column::Boolean->new(...);
  $col->make_methods(...);
  ...

=head1 DESCRIPTION

Objects of this class store and manipulate metadata for boolean 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::Scalar>. Inherited methods that are not overridden will not be documented a second time here.  See the L<Rose::DB::Object::Metadata::Column::Scalar> documentation for more information.

=head1 OBJECT METHODS

=over 4

=item B<parse_value DB, VALUE>

Parse VALUE and return true or false according to how the underlying database would view VALUE as the value for a boolean column.  DB is a L<Rose::DB> object that is used as part of the parsing process.  Both arguments are required.

=item B<type>

Returns "boolean".
