trait Projection

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

`` `trait` Projection
  `extends` MutableIterableProjection `with` Projection

Direct Known Subclasses:
  Map.Lense.Projection, Map.Filter.Projection, SortedMap.Projection

Method Summary
`override def` | filterKeys (p : (K) => Boolean) : Map[K, E] filter based on keys only
`override def` | map [B](f : ((K, E)) => B) : MutableIterable[B] Returns the iterable resulting from applying the given function `f` to each element of this iterable. Unlike `map` in `Iterable`, this API is not strict and will terminate on infinite-sized collections.

Method Details

`override` `def` filterKeys(p : (K) => Boolean) : Map[K, E]

  filter based on keys only

Overrides
  Projection.filterKeys

`override` `def` map[B](f : ((K, E)) => B) : MutableIterable[B]

  Returns the iterable resulting from applying the given function `f` to each element of this iterable. Unlike `map` in `Iterable`, this API is not strict and will terminate on infinite-sized collections.

Parameters
  `f -` function to apply to each element.
Returns
  `f(a0), ..., f(an)` if this iterable is `a0, ..., an`.
