def addAll(elems: IterableOnce[(K, V)]): Growable.this.type

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

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

Value parameters

elems

def knownSize: Int

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

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

Returns

The number of elements. The default implementation always returns -1.

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

Gives a hint that the result of this builder is expected to have the same size as the given collection, plus some delta.

Gives a hint that the result of this builder is expected to have the same size as the given collection, plus some delta.

This method provides a hint only if the collection has a known size, as specified by the following pseudocode:

if (coll.knownSize != -1)
  if (coll.knownSize + delta <= 0) sizeHint(0)
  else sizeHint(coll.knownSize + delta)

If the delta is negative and the result size is known to be negative, then the size hint is issued at zero.

Some builder classes will optimize their representation based on the hint. However, builder implementations are required to work correctly even if the hint is wrong, i.e., if a different number of elements is added.

Value parameters

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 (zero if omitted).

def sizeHint(size: Int): Unit

Gives a hint how many elements are expected to be added in total by the time result is called.

Gives a hint how many elements are expected to be added in total by the time result is called.

Some builder classes will optimize their representation based on the hint. However, builder implementations are required to work correctly even if the hint is wrong, e.g., a different number of elements is added, or the hint is out of range.

The default implementation simply ignores the hint.

Value parameters

size

the hint how many elements will be added.

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.

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.

Value parameters

boundingColl

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

size

the hint how many elements will be added.

Adds two or more elements to this growable collection.

Value parameters

elem1

the first element to add.

elem2

the second element to add.
