ObjCount() - Call to nonexistent function | 2.0-a097-60f26de Topic is solved

[Flipeador]

Code: Select all

MsgBox ObjCount({}) ; Call to nonexistent function
MsgBox {1:0,2:0}.Count() ; 2

.. and it does not appear in the list of methods:

Not in the list of methods, but the example is there below:

Count := Object.Count()
Returns the number of key-value pairs present in the object.

Code: Select all

MsgBox % {A: 1, Z: 26}.Count()    ;  2
MsgBox % ["A", "B", "C"].Count()  ;  3
MsgBox % ["A",    , "C"].Count()  ;  2

Edit: I do see it says Object.Count, and not ObjCount

Just ran this, the msgbox says "4":

Code: Select all

myObject := Array("1","2","3","4")
msgbox myObject.Count()

Each method also has an equivalent function, which can be used to bypass any custom behaviour implemented by the object [..]

btw: works well on AHKv1.

I see what you mean now. Point taken.
EDIT: As you say, it works in V1, with the appropriate tweaking:

Code: Select all

myObject := Array("1","2","3","4")
x := myObject.Count()
msgbox %x% ; "4"

y := ObjCount(myObject) ; also "4"
msgbox %y%

It's not in the built-in function array in script.cpp. (Lexikos probably overlooked it, since it's just one line missing).

BIFn(ObjCount, 1, 1, BIF_ObjXXX),

After BIFn(ObjClone, 1, 1, BIF_ObjXXX),

If you need it right now to finish something.

Yes, you are right. I had not seen the source code. It's nothing important. Thank you.

[lexikos]

Yes, it was overlooked when I merged with v1. The v1 code base uses a giant if-else-if ladder instead of a table of functions.

[2020-06-28: Note that ObjCount has since been renamed to ObjOwnPropCount, although more typically one would use myMap.Count. See v2.0-a104-3e7a969d.]
