RightProjection

Returns false if Left or returns the result of the application of the given function to the Right value.

Right(12).right.exists(_ > 10)  // true
Right(7).right.exists(_ > 10)   // false
Left(12).right.exists(_ > 10)   // false

Returns None if this is a Left or if the given predicate p does not hold for the right value, otherwise, returns a Right.

Right(12).right.filterToOption(_ > 10) // Some(Right(12))
Right(7).right.filterToOption(_ > 10)  // None
Left(12).right.filterToOption(_ > 10)  // None

Returns true if Left or returns the result of the application of the given function to the Right value.

Right(12).right.forall(_ > 10) // true
Right(7).right.forall(_ > 10)  // false
Left(12).right.forall(_ > 10)  // true

Executes the given side-effecting function if this is a Right.

Right(12).right.foreach(x => println(x)) // prints "12"
Left(12).right.foreach(x => println(x))  // doesn't print

Returns the value from this Right or the given argument if this is a Left.

Right(12).right.getOrElse(17) // 12
Left(12).right.getOrElse(17)  // 17

The given function is applied if this is a Right.

Right(12).right.map(x => "flower") // Result: Right("flower")
Left(12).right.map(x => "flower")  // Result: Left(12)

Returns a Some containing the Right value if it exists or a None if this is a Left.

Right(12).right.toOption // Some(12)
Left(12).right.toOption // None

Returns a Seq containing the Right value if it exists or an empty Seq if this is a Left.

Right(12).right.toSeq // Seq(12)
Left(12).right.toSeq // Seq()

Returns None if this is a Left or if the given predicate p does not hold for the right value, otherwise, returns a Right.

Right(12).right.filter(_ > 10) // Some(Right(12))
Right(7).right.filter(_ > 10)  // None
Left(12).right.filter(_ > 10)  // None

Returns the value from this Right or throws NoSuchElementException if this is a Left.

Right(12).right.get // 12
Left(12).right.get // NoSuchElementException
