Check if chest is open.

Is there a way to check in the code if a chest is open?

I found the code to open it:

this.world.addBlockEvent(tileEntity.getPos(), tileEntity.getBlockType(), 1, 1);
            this.world.notifyNeighborsOfStateChange(tileEntity.getPos(), tileEntity.getBlockType());
            this.world.notifyNeighborsOfStateChange(tileEntity.getPos().down(), tileEntity.getBlockType());

and can close it with:

this.world.addBlockEvent(tileEntity.getPos(), tileEntity.getBlockType(), 1, 0);
            this.world.notifyNeighborsOfStateChange(tileEntity.getPos(), tileEntity.getBlockType());
            this.world.notifyNeighborsOfStateChange(tileEntity.getPos().down(), tileEntity.getBlockType());

but is there a way to detect if it has been opened already?
