def collectAll[B](implicit ev: ClassTag[B]): Iterator[B]

collects all elements of the given class (beware of type-erasure)

Attributes

def countTrav: Iterator[Int]
def dedup: Iterator[A]

Deduplicate elements of this traversal - a.k.a. distinct, unique, ...

Deduplicate elements of this traversal - a.k.a. distinct, unique, ...

Attributes

def dedupBy(fun: A => Any): Iterator[A]

deduplicate elements of this traversal by a given function

deduplicate elements of this traversal by a given function

Attributes

def head: A
def headOption: Option[A]
def help[B >: A](implicit elementType: ClassTag[B], searchPackages: DocSearchPackages): String

Print help/documentation based on the current elementType A. Relies on all step extensions being annotated with @Traversal / @Doc Note that this works independently of tab completion and implicit conversions in scope - it will simply list all documented steps in the classpath
