          public JSONCollection()

  - ### Method Detail

    - #### toString

          public String toString()

      Converts this JSON collection into a parsable string representation. Warning: This method assumes that the data structure is acyclical. Starting in release 5.2, the result will be pretty printed for readability.
      Overrides:
        `toString` in class `Object`
      Returns:
        a printable, displayable, portable, transmittable representation of the object, beginning with `{` (left brace) and ending with `}` (right brace).

    - #### toString

          public String toString(boolean compact)

      Converts the JSONObject to a compact or pretty-print string representation
      Parameters:
        `compact` - if true, return minimal format string.
      Since:
        5.2.0

    - #### toCompactString

          public String toCompactString()

      Prints the JSONObject as a compact string (not extra punctuation). This is, essentially, what Tapestry 5.1 did inside `toString()`.

    - #### print

          public void print(PrintWriter writer,
                            boolean compact)

      Prints the JSONObject to the write (compactly or not).
      Parameters:
        `writer` - to write content to
        `compact` - if true, then write compactly, if false, write with pretty printing
      Since:
        5.2.1

    - #### print

          public void print(PrintWriter writer)

      Prints the JSONObject to the writer compactly (with no extra whitespace).

    - #### prettyPrint

          public void prettyPrint(PrintWriter writer)

      Prints the JSONObject to the writer using indentation (two spaces per indentation level).
