Rose::DB::Object::Metadata::Column::Interval
Interval column metadata.

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


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


METHOD MAP

get_set
the Rose::DB::Object::MakeMethods::Generic manpage, date, ...

get
the Rose::DB::Object::MakeMethods::Time manpage, date, ...

get_set
the Rose::DB::Object::MakeMethods::Time manpage, 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 the DateTime::Duration manpage object created by this column will have its mode set to MODE. Otherwise, the end_of_month parameter will not be passed to the the DateTime::Duration manpage constructor.

Valid modes are wrap, limit, and preserve. See the documentation for the DateTime::Duration manpage for a full explanation.

parse_value DB, VALUE
Convert VALUE to the equivalent the DateTime::Duration manpage object. VALUE maybe returned unmodified if it is a valid interval keyword or otherwise has special meaning to the underlying database. DB is a the Rose::DB manpage 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''.
