The
JsonGenerator class can be responsible for writing JSON data to the stream instead of building the object model in memory. The list of settings that can be turned on/off exists in the enumeration JsonGenerator.Feature, which contains the static method values( ) , which returns a An array containing constants of this enumeration type.
public static enum JsonGenerator.Feature extends Enum<JsonGenerator.Feature>
import java.io.*; import com.fasterxml.jackson.core.*; public class JsonGeneratorSettingsTest { public static void main(String[] args) throws IOException { StringWriter writer = new StringWriter(); JsonFactory jsonFactory = new JsonFactory(); JsonGenerator jsonGenerator = jsonFactory.createGenerator(writer); for(JsonGenerator.Feature feature : JsonGenerator.Feature.values()) { boolean result = jsonGenerator.isEnabled(feature); System.out.println(feature.name() + ":" + result); } jsonGenerator.close(); } }
