public class JsonSyntaxParser
extends Object
implements org.apache.lucene.queryparser.flexible.core.parser.SyntaxParser

Parser for the SIREN's JSON query syntax

This parser is based on the Jackson's JSON parser and uses internally an ObjectMapper to create a tree model of the JSON data. The tree model is then traversed using a property-centric visitor model. The parser works as follows:

1. The JSON data is parsed and a JSON tree model is created.
2. The tree model is then traversed using JsonPropertyParsers. For each property found in the tree model, the corresponding JsonPropertyParser is applied.
