NAME

Top

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

SYNOPSIS

Top

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

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

DESCRIPTION

Top

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

METHOD MAP

Top

get_set

Rose::DB::Object::MakeMethods::Generic, integer, interface => 'get_set', ...
