public class JSONCreateFunction
extends cascading.nested.core.NestedCreateFunction<JsonNode,ArrayNode>

Class JSONCreateFunction provides for the ability to simply set multiple tuple values onto a new JSON object.

If a SerPredicate is supplied, it will be tested on the current value, if true, the value will be set on the final JSON object. This is useful for prevent null values from being set, artificially increasing the size of the final object.
