Call to Item class when placed into ItemFrames

[Draco18s]

As a result of trying to do attribute boosts when the player owns an item, and trying to avoid performing a complete inventory check onEntityLivingUpdate every N frames for every living entity in order to determine if the item was no longer owned, I have run into an issue:

 

For chests (and chest like objects) I was able to get around the problem by revoking the boost if a container GUI was active.

 

However for ItemFrames this never occurs, the item is simply removed from the player's hand instantly.

 

What I would like would be an additional call in ItemStack's setItemFrame method to tell the ItemStack's item class that it was placed into an ItemFrame

 

i.e. something like this:

 

    public void setItemFrame(EntityItemFrame par1EntityItemFrame)
    {
        this.itemFrame = par1EntityItemFrame;
        this.getItem().nowInFrame(par1EntityItemFrame);
    }

 

This function would be called once with the intent that any effect the Item normally applies to the player can be properly toggled off.

 

It would be nice if there was a similar function for when it's placed into a chest (or other container), but not strictly necessary due to the workaround I have.
