Class JSONSelector

java.lang.Object

org.qbroker.json.JSONSelector

public class JSONSelector
extends java.lang.Object

JSONSelector is to evaluate JSON data with patterns or number ranges. The method of evaluate() returns true if the selector matches the JSON data. Otherwise, it returns false. It supports 3 types of selectors, Pattern, DataSet and Map with keys for JSON Paths and values for patterns or ranges.

JSONSelector of type 1 or type 3 can be used to store data for overloading. One example is to store the json path on the current JSON data for modifications. The method of getValue() returns the original string from type 1 selector only. The method of getValue(String key) returns the String value at the given key from type 3 selector only.
