Package javax.json.stream
Interface JsonParserFactory
public interface JsonParserFactory
Factory for creating
JsonParser
instances. If a factory
instance is configured with a configuration, the configuration applies
to all parser instances created using that factory instance.
The class Json
also provides methods to create
JsonParser
instances, but using JsonParserFactory
is
preferred when creating multiple parser instances as shown in the following
example:
JsonParserFactory factory = Json.createParserFactory();
JsonParser parser1 = factory.createParser(...);
JsonParser parser2 = factory.createParser(...);
All the methods in this class are safe for use by multiple concurrent threads.
