public class JSONPathQuery
extends PathQuery<JSONResource,Object>

Create a path query for a JSON object. Usualy this is done by calling Resty.path(...) A JSONPathQuery is similar to JsonPath or XPath in that you can create access paths into an JSON object. It uses dot '.' as a path separator and [] to access arrays. The array index is either a number or an expression to evaluate for each object in the array. The first matching object is returned. I.e.

store.book[price>7 && price<12.999].author

In the example above the JSON object with a prive value between 7 and 12.999 is selected and the author returned. Boolean expressions are supported with && (and), || (or), ! (not). Values can be compared with =,<,>.
