OB Keys
OB Keys ( object ) -> Function result
| Parameter | Type | Description | |
|---|---|---|---|
| object | Object | → | Object to return property names |
| Function result | Collection | ← | Collection of property names (strings) |
This command is not thread-safe, it cannot be used in preemptive code.
Description
The OB Keys command returns a collection of strings containing all of the enumerable property names of the object.
Only first-level property names are returned (property names of sub-objects are not returned). The order of names within the returned collection follows the definition order of the properties.
Example
You want a collection with all first-level property names of an object:
var $person : Object
var $col : Collection
$person:=New object
$person.lastName:="Smith"
$person.firstName:="Jenny"
$person.children:=New object("Mary";12;"Mark";8)
$col:=OB Keys($person)
//$col[0]="lastName"
//$col[1]="firstName"
//$col[2]="children"
