LongMapBuilder

scala.collection.mutable.LongMap$.LongMapBuilder
final class LongMapBuilder[V] extends ReusableBuilder[(Long, V), LongMap[V]]

This builder can be reused to create multiple instances.

Concrete methods

override def addOne(entry: (Long, V)): LongMapBuilder.this.type

Adds a single element to this growable collection.

Adds a single element to this growable collection.

Attributes

elem

the element to add.

Returns:

the growable collection itself

Definition Classes
Source:
LongMap.scala
def clear(): Unit

Clears the contents of this builder.

Clears the contents of this builder. After execution of this method, the builder will contain no elements.

If executed immediately after a call to result(), this allows a new instance of the same type of collection to be built.

Attributes

Source:
LongMap.scala
override def knownSize: Int

Attributes

Returns:

The number of elements in the collection under construction, if it can be cheaply computed, -1 otherwise. The default implementation always returns -1.

Definition Classes
Source:
LongMap.scala
def result(): LongMap[V]

Produces a collection from the added elements.

Produces a collection from the added elements.

After a call to result, the behavior of all other methods is undefined save for clear(). If clear() is called, then the builder is reset and may be used to build another instance.

Attributes

Returns:

a collection containing the elements added to this builder.

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.

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.

Attributes

coll

the collection which serves as a hint for the result's size.

delta

a correction to add to the coll.size to produce the size hint.

def sizeHint(size: Int): Unit

Gives a hint how many elements are expected to be added when the next result is called.

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.

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.

Attributes

boundingColl

the bounding collection. If it is an IndexedSeqLike, then sizes larger than collection's size are reduced.

final def +=(elem1: (Long, V), elem2: (Long, V), elems: (Long, V)*): Growable.this.type

Adds two or more elements to this growable collection.

Adds two or more elements to this growable collection.

Attributes

elem1

the first element to add.

elem2

the second element to add.

elems

the remaining elements to add.

Returns:

the growable collection itself
