Method until

java/src/org/openqa/selenium/support/ui/Wait.java:45–45

Implementations should wait until the condition evaluates to a value that is neither null nor false. Because of this contract, the return type must not be Void. If the condition does not become true within a certain time (as defined by the implementing class), this method will throw a non-specif

(Function<? super F, ? extends V> isTrue)

   * @return truthy value from the isTrue condition
   */
  <V extends @Nullable Object> @NonNull V until(Function<? super F, ? extends V> isTrue);
}
