Class scala.collection.mutable.LongMapBuilder

final class LongMapBuilder[V] extends ReusableBuilder[(Long, V), LongMap[V]]

A builder for instances of LongMap.

This builder can be reused to create multiple instances.

final def ++=(xs: IterableOnce[(Long, V)]): LongMapBuilder[V]

Alias for addAll

final def +=(elem: (Long, V)): LongMapBuilder[V]

Alias for addOne

Source

def addAll(xs: IterableOnce[(Long, V)]): LongMapBuilder[V]

Adds all elements produced by an IterableOnce to this growable collection.

Source

def mapResult[NewTo](f: LongMap[V] => NewTo): Builder[(Long, V), NewTo]

A builder resulting from this builder my mapping the result using f.

Source

final def sizeHint(coll: IterableOnce[_], delta: Int): Unit

Gives a hint that one expects the result of this builder to have the same size as the given collection, plus some delta. This will provide a hint only if the collection has a known size Some builder classes will optimize their representation based on the hint. However, builder implementations are still required to work correctly even if the hint is wrong, i.e. a different number of elements is added.

Source

def sizeHint(size: Int): Unit

Gives a hint how many elements are expected to be added when the next result is called. Some builder classes will optimize their representation based on the hint. However, builder implementations are still required to work correctly even if the hint is wrong, i.e. a different number of elements is added.

Source

final def sizeHintBounded(size: Int, boundingColl: Iterable[_]): Unit

Gives a hint how many elements are expected to be added when the next result is called, together with an upper bound given by the size of some other collection. Some builder classes will optimize their representation based on the hint. However, builder implementations are still required to work correctly even if the hint is wrong, i.e. a different number of elements is added.
