A data object, representing the times associated with a benchmark measurement.
CAPTION | = | " user system total real\n" |
Default caption, see also Benchmark::CAPTION |
||
FORMAT | = | "%10.6u %10.6y %10.6t %10.6r\n" |
Default format string, see also Benchmark::FORMAT |
[R] | cstime | System CPU time of children |
[R] | cutime | User CPU time of children |
[R] | label | Label |
[R] | real | Elapsed real time |
[R] | stime | System CPU time |
[R] | total | Total time, that is |
[R] | utime | User CPU time |
Returns an initialized Tms object which has
utime
as the user CPU time, stime
as the system
CPU time, cutime
as the children's user CPU time,
cstime
as the children's system CPU time,
real
as the elapsed real time and label
as the
label.
Returns the contents of this Tms object as a formatted string, according to a format string like that passed to Kernel#format. In addition, format accepts the following extensions:
%u
-
Replaced by the user CPU time, as reported by #utime.
%y
-
Replaced by the system CPU time, as reported by stime (Mnemonic: y of “s*y*stem”)
%U
-
Replaced by the children's user CPU time, as reported by #cutime
%Y
-
Replaced by the children's system CPU time, as reported by #cstime
%t
-
Replaced by the total CPU time, as reported by #total
%r
-
Replaced by the elapsed real time, as reported by #real
%n
-
Replaced by the label string, as reported by #label (Mnemonic: n of “*n*ame”)
If format is not given, FORMAT is used as default value, detailing the user, system and real elapsed time.

Returns a new 6-element array, consisting of the label, user CPU time, system CPU time, children's user CPU time, children's system CPU time and elapsed real time.
Returns a new Tms object obtained by memberwise
operation op
of the individual times for this Tms object with those of the other Tms object.
op
can be a mathematical operation such as +
