scala.collection.jcl.Set
class Filter

[source: `scala/collection/jcl/Set.scala`]

`` `class` Filter(p : (A) => Boolean)
  `extends` Filter `with` Set[A]

  Base implementation of a filtered collection

Direct Known Subclasses:
  SortedSet.Filter

Method Summary
`override def` | projection : Projection returns a facade that can be used to call non-strict `filter`, `map`, and `flatMap` methods that build projections of the collection.
`override def` | retain (p0 : (A) => Boolean) : Unit Method `retain removes all elements from the set for which the predicate `p` yields the value `false`.`
