In order to set or reset the Object for using to write to use for writing Java objects as JsonContent, we use this method.Ībstract JsonGenerator setFeatureMask(int mask)-Bulk set method for (re)setting states of all standard JsonGenerator.Features It is used to define the custom escapes factory uses for JsonGenerators it creates.Ībstract JsonGenerator setCodec(ObjectCodec oc) JsonGenerator setCharacterEscapes(CharacterEscapes esc) It is used to check whether the given feature is enabled or not.

It is used to determine whether the current generator is closed or not.Ībstract boolean isEnabled(JsonGenerator.Feature f) It is used to access the schema that the current parser uses if any. It is an accessor, i.e., used to check whether the current generator has a configured PrettyPrinter. It is used to get access to Object, i.e., used as the target for the generated output. It is an accessor method, i.e., used to test what is the highest unescaped character configured for this generator.

In order to get the state of all standard JsonGenerator.Features, we use this bulk access method. It is used to access the Object used to write Java Object as JSON content. It is used to access the custom escapes factory uses for JsonGenerators it creates. flushing any buffered data to the underlying target. It is used to enable the given parser features.ġ. In order to copy the data of the current event and following events that it encloses pointed by the given parser instance, we use this method.Ībstract JsonGenerator disable(JsonGenerator.Feature f)Ībstract JsonGenerator enable(JsonGenerator.Feature f) In order to copy the data of the current event pointed by the given parser instance, we use this method. It is used to disable or enable the given feature. JsonGenerator configure(JsonGenerator.Feature f, boolean state) It is used for closing the current generator to stop writing content. It is used to check whether the underlying data format supports some kind of Type Ids natively or not.Ībstract void close() - Method called to close this generator so that no more content can be written. It is used to check whether the underlying data format supports some kind of Object Ids natively or not. It is used to check whether the underlying data format supports 'native' binary data or not. It is used to check whether the given schema can be used with the current generator or not. The method is used for checking whether it is ok to omit the writing of Object fields or not.īoolean canUseSchema(FormatSchema schema) It is used for calling appropriate write method to given untyped Object.īoolean canOmitFields() - Introspection method to call to check whether it is ok to omit writing of Object fields or not. Protected void _writeSimpleObject(Object value) It is a helper method that is used to construct and throw JsonGenerationException with the specified base message. It is an object which is used for handling the pretty-printing at the time of output. Constructors of the JsonGenerator Class S.N. Public Person(String name, int height, int weight) we annotate a method with its content will be returned in the object serialization.Protected PrettyPrinter _cfgPrettyPrinter Once we added it to our project, let’s create two classes that we are going to use to instantiate our objects and test our serialization. It is very simple to serialize an object using Jackson, all you need to do is add it to your project using a dependency manager like Maven or add it manually.

Now let’s dive into how to use Jackson to serialize Java objects. So our serialized objects are going to look like this: Deserialization, as you may already have inferred, is the process of converting the serialized form of an object back into a copy of the original object.įor this post, we’re gonna be serializing our objects to JSON using the Jackson library. Serialization is the process of converting the state of an object to a byte stream in a way that the byte stream can be reverted into a copy of the original object. Before we start working with serialization and deserialization in Java we need to understand what these terms actually mean.
