objectEntries
objectEntries ( object : object ) : collection
| Parameter | Type | Description | |
|---|---|---|---|
| object | object | -> | Object to return contents |
| Result | collection | <- | Collection of objects with key / value properties |
Description
The objectEntries command returns a collection of objects containing the contents of the object as key / value property pairs.
Each returned object contains the following properties:
| Property | Type | Description |
|---|---|---|
| key | string | Enumerable property name of the object |
| value | variant | Enumerable property value of the object |
Only first-level property names are returned (property names of sub-objects are not returned). The order of properties within the returned collection follows the definition order of the properties.
Example
Using an object as an hash map (key / value system) provides a quick and direct access to data, just like when using an index (e.g., if we need Mary's age, we can write: persons["Mary"])
var individual, persons : object
var names, ages : collection
var result1, result2 : string
persons = newObject
persons["John"] = 42
persons["Andy"] = 24
persons["Mary"] = 30
persons["Paul"] = 50
result1 = "The average age is "+string(objectValues(persons).average())
result1 = result1+"/rThere are "+string(objectKeys(persons).length)+" persons"
ages = objectEntries(persons).query("value>:1",25)
result2 = "There are "+string(ages.length)+" persons who are over 25"
result2 = result2+"/rTheir names are: "+ages.extract("key").join("-")
