33. final def withFilter(p: (T) ⇒ Boolean): WithFilter

    

    Creates a non-strict filter, which eventually converts this to a Failure if the predicate is not satisfied.

    Creates a non-strict filter, which eventually converts this to a Failure if the predicate is not satisfied.

    Note: unlike filter, withFilter does not create a new Try. Instead, it restricts the domain of subsequent map, flatMap, foreach, and withFilter operations.

    As Try is a one-element collection, this may be a bit overkill, but it's consistent with withFilter on Option and the other collections.

    p

    the predicate used to test elements.

    returns

    an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this Try which satisfy the predicate p.
