Value Members

  1. 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.

  2. 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.

  3. def flatten[QO](implicit ev: <:<[P, Rep[Option[QO]]]): Rep[Option[QO]]

    Flatten a nested Option.

  4. def fold[B, BP](ifEmpty: B)(f: (P) => B)(implicit shape: Shape[FlatShapeLevel, B, _, BP]): BP

    Apply f to the value inside this Option, if it is non-empty, otherwise return ifEmpty.

    AnyVal → Any
  6. def getOrElse[M, P2 <: P](default: M)(implicit shape: Shape[FlatShapeLevel, M, _, P2], ol: OptionLift[P2, O]): Unconst[P]

    Get the value inside this Option, if it is non-empty, otherwise the supplied default.

  7. def isDefined: Rep[Boolean]

    Check if this Option is non-empty.

  8. def isEmpty: Rep[Boolean]

    Check if this Option is empty.

  9. def map[Q, QO](f: (P) => Q)(implicit ol: OptionLift[Q, Rep[Option[QO]]]): Rep[Option[QO]]

    Transform the value inside this Option

  10. def nonEmpty: Rep[Boolean]

    Check if this Option is non-empty.
