19.2 JSON Processing in the Java EE Platform
Java EE includes support for JSR 353, which provides an API to parse, transform, and query JSON data using the object model or the streaming model described in Generating and Parsing JSON Data. The Java API for JSON Processing contains the following packages.
-
The
javax.jsonpackage contains a reader interface, a writer interface, and a model builder interface for the object model. This package also contains other utility classes and Java types for JSON elements. Table 19-1 lists the main classes and interfaces in this package. -
The
javax.json.streampackage contains a parser interface and a generator interface for the streaming model. Table 19-2 lists the main classes and interfaces in this package.
