/**
* JsonPath is an alternative to using XPath for easily getting values from a Object document. It follows the
* Groovy GPath syntax when getting an object from the document. You can regard it as an alternative to XPath for JSON.
* E.g. given the following Object document:
*
* { "store": {
* "book": [
* { "category": "reference",
* "author": "Nigel Rees",
* "title": "Sayings of the Century",
* "price": 8.95
* },
* { "category": "fiction",
* "author": "Evelyn Waugh",
* "title": "Sword of Honour",
* "price": 12.99
* },
* { "category": "fiction",
* "author": "Herman Melville",
* "title": "Moby Dick",
* "isbn": "0-553-21311-3",
* "price": 8.99
* },
* { "category": "fiction",
* "author": "J. R. R. Tolkien",
* "title": "The Lord of the Rings",
* "isbn": "0-395-19395-8",
* "price": 22.99
* }
* ],
* "bicycle": {
* "color": "red",
* "price": 19.95
* }
* }
* }
*
* To get a list of all book categories:
*
* List<String> categories = with(Object).get("store.book.category");
*
*
* Get the first book category:
*
* String category = with(Object).get("store.book[0].category");
*
*
* Get the last book category:
*
* String category = with(Object).get("store.book[-1].category");
*
*
* Get all books with price between 5 and 15:
*
* List<Map> books = with(Object).get("store.book.findAll { book -> book.price >= 5 && book.price <= 15 }");
*
*
* The JsonPath implementation of rest-assured uses a Groovy shell to evaluate expressions so be careful when injecting
* user input into the expression. For example avoid doing this:
*
* String name = System.console().readLine();
* List<Map> books = with(Object).get("store.book.findAll { book -> book.author == " + name + " }");
*
* Instead use the {@link #param(java.lang.String, java.lang.Object)} method like this:
*
* String name = System.console().readLine();
* List<Map> books = with(Object).param("name", name).get("store.book.findAll { book -> book.author == name }");
*
