Constructor Detail

• public StreamingJsonDelegate(Writer w, boolean first)

• public 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)

• public void call(String name, Object value)

  Writes the name and value of a JSON attribute

  throws:

  IOException

  Parameters:

  name - The attribute name

  value - The value

  Writes the name and value of a JSON attribute

  throws:

  IOException

  Parameters:

  name - The attribute name

  value - The value

• public void call(String name, @DelegatesTo(StreamingJsonDelegate.class) Closure value)

  Writes the name and another JSON object

  throws:

  IOException

  Parameters:

  name - The attribute name

  value - The value

• public void call(String name, JsonUnescaped json)

  Writes an unescaped value. Note: can cause invalid JSON if passed JSON is invalid

  throws:

  IOException

  Parameters:

  name - The attribute name

  json - The value

• public void call(String name, Writable json)

  Writes the given Writable as the value of the given attribute name

  throws:

  IOException

  Parameters:

  name - The attribute name

  json - The writable value
