NEVER
Never cache. Perform the calculation every time the method is called. -
LAZY
Cache the result of the first invocation ofhashCode
and use it for subsequent invocations. This can improve performance if all fields used for calculating thehashCode
are immutable and thus every invocation ofhashCode
will always return the same value. Do not use this if there's any chance that different invocations ofhashCode
might return different values.
