protected boolean first

protected StreamingJsonBuilder.StreamingJsonDelegate.State state

protected final Writer writer

Constructor Detail

public StreamingJsonBuilder.StreamingJsonDelegate(Writer w, boolean first)

public StreamingJsonBuilder.StreamingJsonDelegate(Writer w, boolean first, JsonGenerator generator)

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)
