Join Alex Theedom for an in-depth discussion in this video Introduction to the streaming model, part of JSON Processing with Java EE.
- [Instructor] The streaming model reads JSON data…one element at a time and fires an event…each time it reaches one of the following elements:…The start and end of an object,…the start and end of an array, a key name,…and any string, number, Boolean, and NULL value.…The parser stops at each event.…It can then either process the element or discard it.…It moves on to the next event…until all elements in the JSON…data stream have been parsed.…This is very efficient low-level API…designed for passing large quantities of JSON data.…
API consists of two principal interfaces,…JsonParser and JsonGenerator.…Both interfaces are located…in the Javax.json.stream package.…The JsonParser interface provides read-only access…to the JSON data as it parses it.…It traverses in the forward direction only.…The next element in the JSON document…is pulled by calling…the next method in the parser interface.…This continues until the data is exhausted.…The JsonGenerator interface provides…a collection of methods that write JSON to a stream.…
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.
