scala.collection.MapOps.WithFilter

class WithFilter[K, +V, +IterableCC[_], +CC <: ([_, _] =>> IterableOps[_, AnyConstr, _])](self: MapOps[K, V, CC, _] & IterableOps[(K, V), IterableCC, _], p: ((K, V)) => Boolean) extends WithFilter[(K, V), IterableCC], Serializable

Specializes WithFilter for Map collection types by adding overloads to transformation operations that can return a Map.

Value parameters
q

the predicate used to test elements.

Attributes
Returns

an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this map collection which also satisfy both p and q predicates.
