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.
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
Returns a new Tms object obtained by memberwise multiplication of the individual times for this Tms object by x.
def *(x); memberwise(:*, x) end
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.
def +(other); memberwise(:+, other) end
Returns a new Tms object obtained by memberwise subtraction of the individual times for the other Tms object from those of this Tms object.
def -(other); memberwise(:-, other) end
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.
def /(x); memberwise(:/, x) end
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).
def add(&blk)
self + Benchmark.measure(&blk)
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).
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
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:
Replaced by the user CPU time, as reported by Tms#utime.
Replaced by the system CPU time, as reported by stime (Mnemonic: y of “s*y*stem”)
Replaced by the children's user CPU time, as reported by Tms#cutime
Replaced by the children's system CPU time, as reported by Tms#cstime
Replaced by the total CPU time, as reported by Tms#total
Replaced by the elapsed real time, as reported by Tms#real
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.
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
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.
def to_a
[@label, @utime, @stime, @cutime, @cstime, @real]
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 +, -, *, /
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)
Benchmark::Tms.new(utime.__send__(op, x),
stime.__send__(op, x),
cutime.__send__(op, x),
cstime.__send__(op, x),
real.__send__(op, x)
