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 lib/benchmark.rb, line 413 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.
# File lib/benchmark.rb, line 429 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 #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.
# File lib/benchmark.rb, line 484 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 lib/benchmark.rb, line 509 def to_a [@label, @utime, @stime, @cutime, @cstime, @real] end
Same as format.
# File lib/benchmark.rb, line 499 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.
op
can be a mathematical operation such as +
