Understanding pointer fields in structs

[spring jay]

any pointers currently alive to an object will prevent that object from being collected

once those OTP objects themselves are collected, then the pointed-to objects become available to collect (if no other pointers to them remain)

Thanks for answer, lets say i have a global map of otps, and there is going to be atleast one otp in that map, are saying all those otps that i removed from map will stay there for ever?

i mean their pointers

[spring jay]

if no pointers to an object remain, it can be collected

i'm not following precisely what you mean by "their pointers"

pointers to them, or pointers that they contain?

[shell orbit]

lets say i have a map of with 100 OTP objects and all of their pointers have values, now when i delete 50 of those otp objects, what happens to deleted objects pointers and values?
