Uniquely identifying an Inventory?

I want to be able to tell when a player opens/closes a certain (virtual) inventory.

I've tried saving the Inventory object in an array, but through a variable debugger, I can see that the object gets changed between the two events happening. I've also had a look at most of the methods, and haven't seen one that jumped out as being a unique way of identifying them.

I know in the past people used the inv.getName(), but now that you can rename a chest whatever, that's quite useless.

I'm not sure if its the same as inventory.getName() but what if you do inventory.getTitle() and compair the titles with .equals or .equalsIgnoreCase + with color checks?

 

Maybe when they open it, rename the chest to their player name, and then display that or something

 

xize I think that colour idea could be good. Have a specific sequence of colours that relate to the type of chest, which would be invisible to the player. The players wouldn't be able to find it easily and rename a chest, but it means I can easily compare it with a static variable.

I'll try that out, and report back!
