NAME¶
Rose::DB::Object::Metadata::Column::Interval - Interval column metadata.
SYNOPSIS¶
use Rose::DB::Object::Metadata::Column::Interval;
$col = Rose::DB::Object::Metadata::Column::Interval->new(...);
$col->make_methods(...);
...
DESCRIPTION¶
Objects of this class store and manipulate metadata for interval 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. Inherited methods
that are not overridden will not be documented a second time here. See the
Rose::DB::Object::Metadata::Column documentation for more information.
METHOD MAP¶
- "get_set"
- Rose::DB::Object::MakeMethods::Generic, date, ...
- "get"
- Rose::DB::Object::MakeMethods::Time, date, ...
- "get_set"
- Rose::DB::Object::MakeMethods::Time, date, ...
See the Rose::DB::Object::Metadata::Column documentation for an explanation of
this method map.
OBJECT METHODS¶
- end_of_month_mode MODE
- This mode determines how math is done on duration objects.
If defined, the "end_of_month" setting for each
DateTime::Duration object created by this column will have its mode set to
MODE. Otherwise, the "end_of_month" parameter will not be passed
to the DateTime::Duration constructor.
Valid modes are "wrap", "limit", and
"preserve". See the documentation for DateTime::Duration for a
full explanation.
- parse_value DB, VALUE
- Convert VALUE to the equivalent DateTime::Duration object.
VALUE maybe returned unmodified if it is a valid interval 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.
- scale [INT]
- Get or set the integer number of places past the decimal
point preserved for fractional seconds. Defaults to 0.
Returns "interval".
- type
- Returns "interval".
