class Benchmark::IPS::Job::Entry

Entries in Benchmark Jobs.

def call_times(times)

Returns:
  • (Integer) - Number of times the +@action+ has been called.

Parameters:
  • times (Integer) -- Times to call +@action+. 
def call_times(times)
  raise '#call_times should be redefined per Benchmark::IPS::Job::Entry instance'
end

def compile_block 

def compile_block

      act = @action
      i = 0
      while i < times

def compile_string(str)

Returns:
  • (Symbol) - :call_times.

Parameters:
  • str (String) -- Code to be compiled. 
def compile_string(str)
  m = (class << self; self; end)
  code = <<-CODE
    def call_times(__total);
      __i = 0

def initialize(label, action)

Raises:
  • (ArgumentError) - Raises when action is not String or not responding to +call+.

Parameters:
  • action (String, Proc) -- Code to be benchmarked.
  • label (#to_s) -- Label of Benchmarked code. 
def initialize(label, action)
  @label = label
  # We define #call_times on the singleton class of each Entry instance.
  # That way, there is no polymorphism for `@action.call` inside #call_times.

  else
    unless action.respond_to? :call
      raise ArgumentError, "invalid action, must respond to #call"
