Method Detail

memoize

public static <T> java.util.function.Supplier<T> memoize(java.util.function.Supplier<T> supplier)

Returns a memoizing supplier. The original supplier will be called at most once, unless the call fails or returns null. Then the call will be repeated.

The returned supplier does not allow null values, i.e. if the supplier returns null, a NullPointerException will be raised.

The returned supplier is Serializable iff the supplier also is. The memoized value will not be serialized.
