47. #### def stringOf(arg: Any, maxElements: Int): String

48. #### def stringOf(arg: Any): String

    Given any Scala value, convert it to a String.

    Given any Scala value, convert it to a String.

    The primary motivation for this method is to provide a means for correctly obtaining a String representation of a value, while avoiding the pitfalls of naïvely calling toString on said value. In particular, it addresses the fact that (a) toString cannot be called on null and (b) depending on the apparent type of an array, toString may or may not print it in a human-readable form.

    arg

      the value to stringify

    returns

      a string representation of arg.
