erm wtf

I dont really understand your question

#

do you want a data structure that only stores unique objects?

sleek verge
#

Lets say theres a record named B and a set named A
now I want it soo that only 1 instance of record B can exist in A at a time

use a map

Its like
Theres an interface named ItemModifier which is implemented by many records, all those records are stored in an set but I dont want more than 2 instances of same record existing in set

tight epoch
# 
Map<Class<?>, Object> map```

hmm

tight epoch
#

each key can only exist once. a hash set is just a hashmap under the hood

sleek verge
#

I guess

tight epoch
#

Set does not provide the functionality you want. but you can replicate it
