NAME

Top

Rose::DB::Object::Metadata::Column::BigInt - Big integer column metadata.

SYNOPSIS

Top

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

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

DESCRIPTION

Top

Objects of this class store and manipulate metadata for big integer (sometimes called "int8") columns in a database. Values are stored internally and returned as Math::BigInt objects. If the Math::BigInt::GMP module is installed, it will be used transparently for better peformance.

This class inherits from Rose::DB::Object::Metadata::Column::Integer. Inherited methods that are not overridden will not be documented a second time here. See the Rose::DB::Object::Metadata::Column::Integer documentation for more information.

METHOD MAP

Top

If perl is compiled to use 64-bit integers, then the method map is:

get_set

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

get

Rose::DB::Object::MakeMethods::Generic, scalar, interface => 'get', ...

get_set

Rose::DB::Object::MakeMethods::Generic, scalar, interface => 'set', ...

Otherwise, the method map is:

get_set

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

get

Rose::DB::Object::MakeMethods::Generic, scalar, interface => 'get', ...

get_set

Rose::DB::Object::MakeMethods::Generic, scalar, interface => 'set', ...

See the Rose::DB::Object::Metadata::Column documentation for an explanation of this method map.
