Constructor Detail

public StreamingJsonBuilder.StreamingJsonDelegate(Writer w, boolean first)

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
