    • toString

      public static String toString(Map<String,Object> options, Object arguments)
      Output the toString for the argument(s) with various options to configure. Configuration options: 
       
      
     
      safe
      provides protection if the toString throws an exception, in which case the exception is swallowed and a dumber default toString is used
      
     
      maxSize
      will attempt to truncate the output to fit approx the maxSize number of characters, -1 means don't truncate
      
     
      inspect
      if false, render a value by its toString, otherwise use its inspect value
      
     
      escapeBackSlashes
      whether characters like tab, newline, etc. are converted to their escaped rendering ('\t', '\n', etc.)
      
     
      verbose
      shorthand to turn on both inspect and escapeBackslashes
      Parameters:
      options - a map of configuration options
      arguments - the argument(s) to calculate the toString for
      Returns:
      the string rendering of the argument(s)
