NAME

Rose::DB::Object::Metadata::Column::TimestampWithTimeZone - Timestamp with time zone column metadata.

SYNOPSIS

Top

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

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

DESCRIPTION

Top

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

METHOD MAP

Top

get_set

Rose::DB::Object::MakeMethods::Date, timestamp, interface => 'get_set', ...

get

Rose::DB::Object::MakeMethods::Date, timestamp, interface => 'get', ...

set

Rose::DB::Object::MakeMethods::Date, timestamp, interface => 'set', ...

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

OBJECT METHODS

Top

parse_value DB, VALUE

Convert VALUE to the equivalent DateTime object. VALUE maybe returned unmodified if it is a valid timestamp keyword or otherwise has special meaning to the underlying database. DB is a Rose::DB object that is used as part of the parsing process. Both arguments are required.
