Join Alex Theedom for an in-depth discussion in this video Introduction to the object model, part of JSON Processing with Java EE.
- [Instructor] The JSON P model is a memory-based model,…which loads the entire JSON document into memory.…As it is loaded, it is parsed into a JSON object structure,…with the JsonValue class at the top.…All classes related to the object model are located…in the the JSON X dot JSON package and consists…of the following principle APIs.…JsonBuilder, JsonReader, and JsonWriter.…As you can see from the tree diagram of the class structure,…every value in the model is of type JsonValue.…
More specific types are defined as JsonObject…or JsonArray.…These three types are the only types necessary…to represent all of the possible data types…in a JSON document.…So, JsonObject represent a JSON object.…The JsonArray represents a JSON array.…And all other values, such as string and number,…are represented by JsonValue.…As mentioned in a previous video, the JsonObject class…implements a map and the JsonArray implements…a list interface.…What this means is that the normal functionality…of maps and collections can be applied to these types,…
In this course, discover how to use the Java Enterprise Edition (EE) JSON-Processing API. With its two programming models, JSON-Processing is one of the simplest ways to generate, query, and parse JSON data, and you'll find that implementing it in your projects is quick and easy. Join Alex Theedom as he covers an array of topics, including how to use both the object model and the streaming model, how to traverse a JSON structure, and how to parse JSON data using the extensive builder APIs. When you wrap up this course, you'll be ready to develop with this essential and powerful API.
