55 "Rose::DB::Object::MakeMethods::Time" creates methods that deal with
56 times, and inherits from Rose::Object::MakeMethods. See the
57 Rose::Object::MakeMethods documentation to learn about the interface.
58 The method types provided by this module are described below.
59 All method types defined by this module are designed to work with
61 objects that are subclasses of (or otherwise conform to the interface
62 of) Rose::DB::Object. In particular, the object is expected to have a
63 db method that returns a Rose::DB-derived object. See the
64 Rose::DB::Object documentation for more details.
65
67 interval
68 Create get/set methods for interval (years, months, days, hours,
69 minutes, seconds) attributes.
70 Options
72 "default"
73 Determines the default value of the attribute.
74 "end_of_month_mode"
76 This mode determines how math is done on duration objects.
77 If defined, the "end_of_month" setting for each
78 DateTime::Duration object created by this method will be
79 set to the specified mode. Otherwise, the "end_of_month"
80 parameter will not be passed to the DateTime::Duration
81 constructor.
82 Valid modes are "wrap", "limit", and "preserve". See the
84 documentation for DateTime::Duration for a full
85 explanation.
86 "hash_key"
88 The key inside the hash-based object to use for the storage
89 of this attribute. Defaults to the name of the method.
90 "interface"
92 Choose the interface. The default is "get_set".
93 "scale"
95 An integer number of places past the decimal point
96 preserved for fractional seconds. Defaults to 0.
97 Interfaces
99 "get_set"
100 Creates a get/set method for a interval (years, months,
101 days, hours, minutes, seconds) attribute. When setting the
102 attribute, the value is passed through the parse_interval
103 method of the object's db attribute. If that fails, a
104 fatal error will occur.
105 When saving to the database, the method will pass the
107 attribute value through the format_interval method of the
108 object's db attribute before returning it.
109 This method is designed to allow interval values to make a
111 round trip from and back into the database without ever
112 being "inflated" into DateTime::Duration objects. Any use
113 of the attribute (get or set) outside the context of
114 loading from or saving to the database will cause the value
115 to be "inflated" using the parse_interval method of the
116 object's db attribute.
117 "get"
119 Creates an accessor method for a interval (years, months,
120 days, hours, minutes, seconds) attribute. This method
121 behaves like the "get_set" method, except that the value
122 cannot be set.
123 "set"
125 Creates a mutator method for a interval (years, months,
126 days, hours, minutes, seconds) attribute. This method
127 behaves like the "get_set" method, except that a fatal
128 error will occur if no arguments are passed.
129 Example:
131 package MyDBObject;
133 use base 'Rose::DB::Object';
135 use Rose::DB::Object::MakeMethods::Time
137 (
138 time =>
139 [
140 't1' => { scale => 6 },
141 't2' => { default => '3 days 6 minutes 5 seconds' },
142 ],
143 );
144 ...
146 $o->t1('5 minutes 0.003 seconds');
148 $dt_dur = $o->t1; # DateTime::Duration object
150 print $o->t1->minutes; # 5
152 print $o->t1->nanosecond; # 3000000
153 time
155 Create get/set methods for time (hours, minutes, seconds)
156 attributes. Fractional seconds up to nanosecond precision are
157 supported.
158 Options
160 "default"
161 Determines the default value of the attribute.
162 "hash_key"
164 The key inside the hash-based object to use for the storage
165 of this attribute. Defaults to the name of the method.
166 "interface"
168 Choose the interface. The default is "get_set".
169 "scale"
171 An integer number of places past the decimal point
172 preserved for fractional seconds. Defaults to 0. The
173 maximum value is 9.
174 Interfaces
176 "get_set"
177 Creates a get/set method for a time attribute. When
178 setting the attribute, the value is passed through the
179 parse_time method of the object's db attribute. If that
180 fails, a fatal error will occur.
181 When saving to the database, the method will pass the
183 attribute value through the format_time method of the
184 object's db attribute before returning it.
185 This method is designed to allow time values to make a
187 round trip from and back into the database without ever
188 being "inflated" into Time::Clock objects. Any use of the
189 attribute (get or set) outside the context of loading from
190 or saving to the database will cause the value to be
191 "inflated" using the parse_time method of the object's db
192 attribute.
193 "get"
195 Creates an accessor method for a time attribute. This
196 method behaves like the "get_set" method, except that the
197 value cannot be set.
198 "set"
200 Creates a mutator method for a time attribute. This method
201 behaves like the "get_set" method, except that a fatal
202 error will occur if no arguments are passed.
203 Example:
205 package MyDBObject;
207 use base 'Rose::DB::Object';
209 use Rose::DB::Object::MakeMethods::Time
211 (
212 time =>
213 [
214 start => { scale => 5 },
215 end => { default => '12:34:56' },
216 ],
217 );
218 ...
220 $o->start('12:34:56.12345');
222 print $o->start->nanosecond; # 123450000
224 print $o->start->as_string; # 12:34:56.12345
225 $o->end('6pm');
227 $tc = $o->end; # Time::Clock object
229 print $o->end->hour; # 18
231 print $o->end->ampm; # PM
232 print $o->end->format('%I:%M %p'); # 6:00 PM
234 $o->end->add(hours => 1);
235 print $o->end->format('%I:%M %p'); # 7:00 PM
