Load Linux bzImage in QEMU?

Question

The code

for ( var i:int = 0; i < markers.length; i++ )
{
    markers[i].addEventListener( MapMouseEvent.CLICK, function( e:Event ):void
    {
        markers[i].openInfoWindow( infoWindows[i] );
    });
    map.addOverlay( markers[i] );
}

I have a list of markers in markers array, and a list of associated InfoWindowOptions in the infoWindow array.

The Issue

By the time the marker is clicked and the anonymous function called, the for loop has already finished and i is now equal to markers.length. So I get an out of bounds error on markers[i] and infoWindows[i].

I would like to create a list of associated functions as well and store it in an array. So I can do something like this instead:

for ( var i:int = 0; i < markers.length; i++ )
{
    markers[i].addEventListener( MapMouseEvent.CLICK, markerListeners[i] );
}

So what I need to know is either,

• How can I can store a list of function references in an array?
• Is there a better way of doing this?

Solution

From qemu's help:

Linux/Multiboot boot specific:
-kernel bzImage use 'bzImage' as kernel image
-append cmdline use 'cmdline' as kernel command line
-initrd file    use 'file' as initial ram disk
-dtb    file    use 'file' as device tree image

A quick test here using Arch's kernel/initrd (qemu -kernel /boot/vmlinuz-linux -initrd /boot/initramfs-linux.img) worked (dropped me into a recovery shell since I didn't provide a root device).

+1 for detailed explanation. Memory leak might be defeated by using weak reference argument in addEventListener, but anonymous handlers approach was bad anyway. I also would not create all InfoWindows at once, if it can be done after marker clicked (this is note for question author).

Yes, that's true, but I don't know enough details about the application to give proper advice. I showed them instantiated that way just so the author could see how a dictionary works.

could I just do qemu -kernel linux/arch/x86/boot/bzimage?

@Coder404 I think so.

Ok thanks! I'll try it and let you know the results!
