class Benchmark::Tms
A data object, representing the times associated with a benchmark measurement.
Constants
- CAPTION
Default caption, see also Benchmark::CAPTION
- FORMAT
Default format string, see also Benchmark::FORMAT
Attributes
System CPU time of children
User CPU time of children
Label
Elapsed real time
System CPU time
Total time, that is utime
+ stime
+ cutime
+ cstime
User CPU time
Public Class Methods
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.
# File benchmark.rb, line 427 def initialize(utime = 0.0, stime = 0.0, cutime = 0.0, cstime = 0.0, real = 0.0, label = nil) @utime, @stime, @cutime, @cstime, @real, @label = utime, stime, cutime, cstime, real, label.to_s @total = @utime + @stime + @cutime + @cstime end
Public Instance Methods
An in-place version of add
. Changes the times of this Tms
object by making it the sum of the times for this Tms
object, plus the time required to execute the code block (blk
).
# File benchmark.rb, line 446 def add!(&blk) t = Benchmark.measure(&blk) @utime = utime + t.utime @stime = stime + t.stime @cutime = cutime + t.cutime @cstime = cstime + t.cstime @real = real + t.real self end
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
Tms#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
Tms#cutime
%Y
-
Replaced by the children’s system CPU time, as reported by
Tms#cstime
%t
-
Replaced by the total CPU time, as reported by
Tms#total
%r
-
Replaced by the elapsed real time, as reported by
Tms#real
%n
-
Replaced by the label string, as reported by
Tms#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.
# File benchmark.rb, line 501 def format(format = nil, *args) str = (format || FORMAT).dup str.gsub!(/(%[-+.\d]*)n/) { "#{$1}s" % label } str.gsub!(/(%[-+.\d]*)u/) { "#{$1}f" % utime } str.gsub!(/(%[-+.\d]*)y/) { "#{$1}f" % stime } str.gsub!(/(%[-+.\d]*)U/) { "#{$1}f" % cutime } str.gsub!(/(%[-+.\d]*)Y/) { "#{$1}f" % cstime } str.gsub!(/(%[-+.\d]*)t/) { "#{$1}f" % total } str.gsub!(/(%[-+.\d]*)r/) { "(#{$1}f)" % real } format ? str % args : str end
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.
# File benchmark.rb, line 526 def to_a [@label, @utime, @stime, @cutime, @cstime, @real] end
Same as format
.
# File benchmark.rb, line 516 def to_s format end
Protected Instance Methods
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 (x
).
op
can be a mathematical operation such as +
, -
, *
, /
# File benchmark.rb, line 540 def memberwise(op, x) case x when Benchmark::Tms Benchmark::Tms.new(utime.__send__(op, x.utime), stime.__send__(op, x.stime), cutime.__send__(op, x.cutime), cstime.__send__(op, x.cstime), real.__send__(op, x.real) ) else Benchmark::Tms.new(utime.__send__(op, x), stime.__send__(op, x), cutime.__send__(op, x), cstime.__send__(op, x), real.__send__(op, x) ) end end
