Package com.api.jsonata4java.expressions.functions

Class EachFunction

java.lang.Object

com.api.jsonata4java.expressions.functions.FunctionBase

com.api.jsonata4java.expressions.functions.EachFunction

All Implemented Interfaces:

Function, Serializable

public class EachFunction
extends FunctionBase
implements Function

From https://docs.jsonata.org/object-functions#each $each(object,function($value, $key) Returns an array containing the values return by the function when applied to each key/value pair in the object. The function parameter will get invoked with two arguments: function(value, name) where the value parameter is the value of each name/value pair in the object and name is its name. The name parameter is optional. Examples $each(Address, function($v, $k) {$k & ": " & $v}) results in [ "Street: Hursley Park", "City: Winchester", "Postcode: SO21 2JN" ]
