Class Instance should destroy itself

General
1

Hi

I’ve got an Array where some Class-Instances are inside.

var PbsToRelease()  as Mod_Playback.Playback

Now at some time, some Class-Instances should be remove themself.
In only know the method with .removeAtRow(x) … but in my case I don’t know the index of each Element because the element inside the Array should destroy/remove itself.
I wanna call a method of the instance to remove itself from the array.
How is that possible?

Thank you, Markus.

If you keep a reference to the array you can do:

theArray.removeAtRow(theArray.IndexOf(instance))

If there is an updated name for IndexOf with the API2 array naming nonsense you’ll need to use that instead

Thank you Jason, I didn’t know that IndexOf will work with Classobjects!

have the constructor get a reference to the array and then when this “playback” is at the point it should remove itself it can find itself in the array and remove itself

Class Playback      
	whatArray() as Mod_Playback.Playback

	Sub Constructor( arrayImIn() as Mod_Playback.Playback)
		self.whatArray = arrayImIn
	End Sub

	Sub EndMe()
		if whatArray is nil then
			return
		end if
		dim index as integer = whatarray.indexof(self)
		if index < 0 then
			return
		end if
		// note if this is the last reference 
		// then we'll see the destructor run next             
		whatArray.remove index
	End Sub
End Class

and add new ones like

   var PbsToRelease()  as Mod_Playback.Playback
 
   PbsToRelease.append new Mod_Playback.Playback(pbsToRelease)

note you cant use the destructor since the instance is in an array and until the item is nil’d theres a reference so the destructor wont be executed :slight_smile:
