Class Public methods
new(utime = 0.0, stime = 0.0, cutime = 0.0, cstime = 0.0, real = 0.0, label = nil)

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 415
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
Instance Public methods
*(x)

Returns a new Tms object obtained by memberwise multiplication of the individual times for this Tms object by x.

# File lib/benchmark.rb, line 460
def *(x); memberwise(:*, x) end
+(other)

Returns a new Tms object obtained by memberwise summation of the individual times for this Tms object with those of the other Tms object. This method and #/() are useful for taking statistics.

# File lib/benchmark.rb, line 447
def +(other); memberwise(:+, other) end
-(other)

Returns a new Tms object obtained by memberwise subtraction of the individual times for the other Tms object from those of this Tms object.

# File lib/benchmark.rb, line 454
def -(other); memberwise(:-, other) end
/(x)

Returns a new Tms object obtained by memberwise division of the individual times for this Tms object by x. This method and #+() are useful for taking statistics.

# File lib/benchmark.rb, line 467
def /(x); memberwise(:/, x) end
add()

Returns a new Tms object whose times are the sum of the times for this Tms object, plus the time required to execute the code block (blk).

# File lib/benchmark.rb, line 424
def add(&blk) # :yield:
  self + Benchmark.measure(&blk)
end
add!(&blk)

An in-place version of add.

# File lib/benchmark.rb, line 431
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
format(format = nil, *args)

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 486
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
to_a()

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 511
def to_a
  [@label, @utime, @stime, @cutime, @cstime, @real]
end
to_s()

Same as format.

# File lib/benchmark.rb, line 501
def to_s
  format
end
Instance Protected methods
memberwise(op, x)

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 +, -, *, /

# File lib/benchmark.rb, line 525
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)
                       )
