All Implemented Interfaces:

Function

public class SpreadFunction
extends FunctionBase
implements Function

From http://docs.jsonata.org/object-functions.html $spread(object) Splits an object containing key/value pairs into an array of objects, each of which has a single key/value pair from the input object. If the parameter is an array of objects, then the resultant array contains an object for every key/value pair in every object in the supplied array.
