Allows items in a collection to be enumerated.
Retrieves the next item or items in an enumeration.
Enum.Next(OutputVar1 [, OutputVar2, ...])
| OutputVar1, OutputVar2 | Receives an implementation-specific value. |
| ... | Additional parameters, if supported. |
| Returns | A non-zero integer if successful, zero if there were no items remaining, or an empty string if parameters were incorrect. |
Enumerators returned by ObjNewEnum() are called once for each key-value pair, and allow up to two parameters:
| OutputVar1 | Receives the key in a key-value pair. |
| OutputVar2 | Receives the value associated with OutputVar1. |
Key-value pairs are returned in an implementation-defined order. That is, they are typically not returned in the same order that they were assigned. Existing key-value pairs may be modified during enumeration, but inserting or removing keys may cause some items to be enumerated multiple times or not at all.
; Create some sample data.
obj := Object("red", 0xFF0000, "blue", 0x0000FF, "green", 0x00FF00)
; Enumerate!
enum := obj._NewEnum()
While enum[k, v]
t .= k "=" v "`n"
MsgBox % t
; Requires [AHK_L 59+]
For k, v in obj
s .= k "=" v "`n"
MsgBox % s
