  - ### Method Detail

    - #### public void call(String name, List<Object> list)

      Writes the name and a JSON array

      throws:
        IOException
      Parameters:
        `name` - The name of the JSON attribute
        `list` - The list representing the array

    - #### public void call(String name, Object... array)

      Writes the name and a JSON array

      throws:
        IOException
      Parameters:
        `name` - The name of the JSON attribute
        `array` - The list representing the array

    - #### public void call(String name, Iterable coll, @DelegatesTo(StreamingJsonDelegate.class) Closure c)

      A collection and closure passed to a JSON builder will create a root JSON array applying the closure to each object in the collection

      Example:

           class Author {
                String name
           }
           def authorList = [new Author (name: "Guillaume"), new Author (name: "Jochen"), new Author (name: "Paul")]

           new StringWriter().with { w ->
               def json = new groovy.json.StreamingJsonBuilder(w)
               json.book {
                  authors authorList, { Author author ->
                   name author.name
                 }
               }

               assert w.toString() == '{"book":{"authors":[{"name":"Guillaume"},{"name":"Jochen"},{"name":"Paul"}]}}'
           }

      Parameters:
        `coll` - a collection
        `c` - a closure used to convert the objects of coll

    - #### public void call(String name, Collection coll, @DelegatesTo(StreamingJsonDelegate.class) Closure c)

      Delegates to call(String, Iterable, Closure)

    - #### public void call(String name, Object value)
