Class Method Details

.extract_from_lines(lines) ⇒ Array<String>

Optionally, you can define this method instead of #extract. The #extract method will call this method if not overrided.

Parameters:

  • lines (Array<String>) —

    Program output, broken in lines, and the line string elements don’t end in linebreak.

Returns:

  • (Array<String>) —

    The N extracted values, as strings.

def self.extract_from_lines(lines)
  values = ['Total Time ', 'ext_time', 'ext_mem'].map do | label |
    Extractor.get_field(lines, label)
  end
  opt_key = '#The optimal value for the given capacity'
  values << Extractor.get_hfield(lines, opt_key)
end

.names ⇒ Array<String>

Note:

To be on the safe side you should create a new array at each call. If you always return a reference to the same array the array can be modified.

Return the field names for each of the elements returned by extract. Ex.:

['Time', 'Max Mem Use', 'opt', ... ]

Returns:

  • (Array<String>) —

    The strings that will be used to make the column names at the BatchExperiment.experiment method.
