Class Method Detail
new(u = 0.0, s = 0.0, cu = 0.0, cs = 0.0, real = 0.0, l = nil)
Returns an initialized Tms object which has u as the user CPU time, s as the system CPU time, cu as the children‘s user CPU time, cs as the children‘s system CPU time, real as the elapsed real time and l as the label.
Instance Method Detail
*(x)
Returns a new Tms object obtained by memberwise multiplication of the individual times for this Tms object by x.
+(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.
-(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.
/(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.
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).
add!()
An in-place version of add.
format(arg0 = 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 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 fmtstr is not given, FMTSTR is used as default value, detailing the user, system and real elapsed time.
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.
to_s()
Same as format.
