public class JsonToMapResourceBuilder
extends AbstractJsonResourceBuilder

Load a JSON array as a resource tuple. This builder reads the input file or resource using a streaming strategy and parse the JSON on the fly.

A new resource tuple is created at each loading. It can be used to atomically switch from one loaded resource to the other. This is however the caller responsibility.
