- def filter[T](p: (P) => T)(implicit wt: CanBeQueryCondition[T]): O
Return this Option if it is non-empty and applying the predicate p to this Option's value returns true.
Return this Option if it is non-empty and applying the predicate p to this Option's value returns true. Otherwise, return None.
- def flatMap[QO](f: (P) => Rep[Option[QO]]): Rep[Option[QO]]
Return the result of applying
f
to this Option's value if this Option is non-empty, otherwise None. - def flatten[QO](implicit ev: <:<[P, Rep[Option[QO]]]): Rep[Option[QO]]
Flatten a nested Option.

Deprecated Value Members

- Definition Classes
- StringFormat
- Annotations
- @deprecated @inline()
- Deprecated
(Since version 2.12.16) Use
formatString.format(value)
instead ofvalue.formatted(formatString)
, or use thef""
string interpolator. In Java 15 and later,formatted
resolves to the new method in String which has reversed parameters.
- def →[B](y: B): (AnyOptionExtensionMethods[O, P], B)

- Deprecated
(Since version 2.13.0) Use
->
instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
