=head1 NAME
Rose::DB::Object::Metadata::Column::Varchar - Variable-length character column metadata.
=head1 SYNOPSIS
use Rose::DB::Object::Metadata::Column::Varchar;
$col = Rose::DB::Object::Metadata::Column::Varchar->new(...);
$col->make_methods(...);

=head1 DESCRIPTION
Objects of this class store and manipulate metadata for variable-length character 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::Character>. Inherited methods that are not overridden will not be documented a second time here. See the L<Rose::DB::Object::Metadata::Column::Character> documentation for more information.
