WithFilter (original) (raw)
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.

Type parameters
B
the element type of the returned collection.
Value parameters
f

Applies a function f to all elements of the filtered outer collection.
Type parameters
U
the type parameter describing the result of function f. This result will always be ignored. Typically U is Unit, but this is not necessary.
Value parameters
f
the function that is applied for its side-effect to every element. The result of function f is discarded.
