Package javax.json.stream

Interface JsonGeneratorFactory

public interface JsonGeneratorFactory
Factory to create JsonGenerator instances. If a factory instance is configured with some configuration, the configuration applies to all generator instances created using that factory instance.

The class Json also provides methods to create JsonGenerator instances, but using JsonGeneratorFactory is preferred when creating multiple generator instances as shown in the following example: 

 
 JsonGeneratorFactory factory = Json.createGeneratorFactory();
 JsonGenerator generator1 = factory.createGenerator(...);
 JsonGenerator generator2 = factory.createGenerator(...);

All the methods in this class are safe for use by multiple concurrent threads.

      out - i/o stream to which JSON is written

    • createGenerator

      JsonGenerator createGenerator(OutputStream out, Charset charset)
      Creates a JSON generator to write JSON text to a byte stream. Characters written to the stream are encoded into bytes using the specified charset. The generator is configured with the factory's configuration.
      Parameters:
      out - i/o stream to which JSON is written
      charset - a charset

    • getConfigInUse

      Map<String,?> getConfigInUse()
      Returns a read-only map of supported provider specific configuration properties that are used to configure the JSON generators. If there are any specified configuration properties that are not supported by the provider, they won't be part of the returned map.
      Returns:
      a map of supported provider specific properties that are used to configure the created generators. The map may be empty but not null
