Rose::DB::Object::MakeMethods::Time - Create time-related methods for
Rose::DB::Object-derived objects.
SYNOPSIS
package MyDBObject;
use base 'Rose::DB::Object';
use Rose::DB::Object::MakeMethods::Time
(
interval =>
[
t1 => { scale => 6 },
t2 => { default => '3 days 6 minutes 5 seconds' },
],
time =>
[
start => { scale => 5 },
end => { default => '12:34:56' },
],
);
...
$o->t1('5 minutes 0.003 seconds');
$dt_dur = $o->t1; # DateTime::Duration object
print $o->t1->minutes; # 5
print $o->t1->nanosecond; # 3000000
$o->start('12:34:56.12345');
print $o->start->nanosecond; # 123450000
print $o->start->as_string; # 12:34:56.12345
$o->end('6pm');
$tc = $o->end; # Time::Clock object
print $o->end->hour; # 18
print $o->end->ampm; # PM
print $o->end->format('%I:%M %p'); # 6:00 PM
$o->end->add(hours => 1);
print $o->end->format('%I:%M %p'); # 7:00 PM
DESCRIPTION
"Rose::DB::Object::MakeMethods::Time" creates methods that deal with times, and inherits
from Rose::Object::MakeMethods. See the Rose::Object::MakeMethods documentation to learn
about the interface. The method types provided by this module are described below.
All method types defined by this module are designed to work with objects that are
subclasses of (or otherwise conform to the interface of) Rose::DB::Object. In particular,
the object is expected to have a db method that returns a Rose::DB-derived object. See
the Rose::DB::Object documentation for more details.
METHODS TYPES
interval
Create get/set methods for interval (years, months, days, hours, minutes, seconds)
attributes.
Options
"default"
Determines the default value of the attribute.
"end_of_month_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
method will be set to the specified 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.
"hash_key"
The key inside the hash-based object to use for the storage of this attribute.
Defaults to the name of the method.
"interface"
Choose the interface. The default is "get_set".
"scale"
An integer number of places past the decimal point preserved for fractional
seconds. Defaults to 0.
Interfaces
"get_set"
Creates a get/set method for a interval (years, months, days, hours, minutes,
seconds) attribute. When setting the attribute, the value is passed through
the parse_interval method of the object's db attribute. If that fails, a
fatal error will occur.
When saving to the database, the method will pass the attribute value through
the format_interval method of the object's db attribute before returning it.
This method is designed to allow interval values to make a round trip from and
back into the database without ever being "inflated" into DateTime::Duration
objects. Any use of the attribute (get or set) outside the context of loading
from or saving to the database will cause the value to be "inflated" using the
parse_interval method of the object's db attribute.
"get"
Creates an accessor method for a interval (years, months, days, hours,
minutes, seconds) attribute. This method behaves like the "get_set" method,
except that the value cannot be set.
"set"
Creates a mutator method for a interval (years, months, days, hours, minutes,
seconds) attribute. This method behaves like the "get_set" method, except
that a fatal error will occur if no arguments are passed.
Example:
package MyDBObject;
use base 'Rose::DB::Object';
use Rose::DB::Object::MakeMethods::Time
(
time =>
[
't1' => { scale => 6 },
't2' => { default => '3 days 6 minutes 5 seconds' },
],
);
...
$o->t1('5 minutes 0.003 seconds');
$dt_dur = $o->t1; # DateTime::Duration object
print $o->t1->minutes; # 5
print $o->t1->nanosecond; # 3000000
time
Create get/set methods for time (hours, minutes, seconds) attributes. Fractional
seconds up to nanosecond precision are supported.
Options
"default"
Determines the default value of the attribute.
"hash_key"
The key inside the hash-based object to use for the storage of this attribute.
Defaults to the name of the method.
"interface"
Choose the interface. The default is "get_set".
"scale"
An integer number of places past the decimal point preserved for fractional
seconds. Defaults to 0. The maximum value is 9.
Interfaces
"get_set"
Creates a get/set method for a time attribute. When setting the attribute,
the value is passed through the parse_time method of the object's db
attribute. If that fails, a fatal error will occur.
When saving to the database, the method will pass the attribute value through
the format_time method of the object's db attribute before returning it.
This method is designed to allow time values to make a round trip from and
back into the database without ever being "inflated" into Time::Clock objects.
Any use of the attribute (get or set) outside the context of loading from or
saving to the database will cause the value to be "inflated" using the
parse_time method of the object's db attribute.
"get"
Creates an accessor method for a time attribute. This method behaves like the
"get_set" method, except that the value cannot be set.
"set"
Creates a mutator method for a time attribute. This method behaves like the
"get_set" method, except that a fatal error will occur if no arguments are
passed.
Example:
package MyDBObject;
use base 'Rose::DB::Object';
use Rose::DB::Object::MakeMethods::Time
(
time =>
[
start => { scale => 5 },
end => { default => '12:34:56' },
],
);
...
$o->start('12:34:56.12345');
print $o->start->nanosecond; # 123450000
print $o->start->as_string; # 12:34:56.12345
$o->end('6pm');
$tc = $o->end; # Time::Clock object
print $o->end->hour; # 18
print $o->end->ampm; # PM
print $o->end->format('%I:%M %p'); # 6:00 PM
$o->end->add(hours => 1);
print $o->end->format('%I:%M %p'); # 7:00 PM
