Java JsonPointerBasedFilter-class And Method Code Example

Here is an example of how to use the JsonPointerBasedFilter class from the Apache Commons IO library:

import org.json.JSONObject;

public class Example {
    public static void main(String[] args) {
        // Create a JSONObject
        JSONObject json = new JSONObject("{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}");

        // Create a JsonPointerBasedFilter that filters out the "name" key from the JSON
        JsonPointerBasedFilter filter = new JsonPointerBasedFilter("/name");

        // Apply the filter to the JSONObject
        json = filter.apply(json);

        // Print the filtered JSON

In this example, the JsonPointerBasedFilter class is being used to filter out the "name" key from the JSON Object. The apply method is used to filter the JSON object and the filtered JSON object is printed.

JsonPointerBasedFilter can be useful in case if you want to filter out specific nodes of a JSON object and don't want to use third party libraries.

It's also worth noting that this class uses JSON Pointer (RFC 6901) to filter the JSON object, So it's important to be familiar with the syntax of JSON Pointer.
