adds two or more elements to this growable collection.
elem1
the first element to add.

the second element to add.
elems
the remaining elements to add.

def result(): AnyRefMap[K, V]
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.
returns
a collection containing the elements added to this builder.

AnyRefMapBuilder → ReusableBuilder → Builder
(defined at scala.collection.mutable.AnyRefMap.AnyRefMapBuilder)
Value Members From scala.collection.mutable.Builder
Creates a new builder by applying a transformation function to the results of
this builder.
NewTo
the type of collection returned by f .
f
the transformation function.
returns
a new builder which is the same as the current builder except that a
transformation function is applied to this builder’s result.

Note
The original builder should no longer be used after mapResult is called.

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.
size
the hint how many elements will be added.

Builder
(defined at scala.collection.mutable.Builder)
def sizeHint(coll: TraversableLike[_, _]): 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 is known to have a cheap size method. Currently this is assumed to
be the case if and only if the collection is of type IndexedSeqLike . 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.
coll
the collection which serves as a hint for the result’s size.

def sizeHintBounded(size: Int, boundingColl: TraversableLike[_, _]): 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.
size
the hint how many elements will be added.
boundingColl
the bounding collection. If it is an IndexedSeqLike, then sizes larger than
collection’s size are reduced.

def toParArray: ParArray[T]
Implicit information
This member is added by an implicit conversion from AnyRefMapBuilder [K, V]
to CollectionsHaveToParArray [AnyRefMapBuilder [K, V], T] performed by
method CollectionsHaveToParArray in scala.collection.parallel. This
conversion will take place only if an implicit value of type (
AnyRefMapBuilder [K, V]) ⇒ GenTraversableOnce [T] is in scope.
