the growable collection itself.
Adds a single element to the builder.
Adds a single element to the builder.
the element to be added.
the builder itself.
adds two or more elements to this growable collection.

Returns true if this combiner has a thread-safe += and is meant to be shared
across several threads constructing the collection.
Returns true if this combiner has a thread-safe += and is meant to be shared
across several threads constructing the collection.
By default, this method returns false.
Clears the contents of this builder.
Clears the contents of this builder. After execution of this method the builder will contain no elements.
Combines the contents of the receiver builder and the other builder,
producing a new builder containing both their elements.
Combines the contents of the receiver builder and the other builder,
producing a new builder containing both their elements.
This method may combine the two builders by copying them into a larger collection,
by producing a lazy view that gets evaluated once result is invoked, or use
a merge operation specific to the data structure in question.
Note that both the receiver builder and other builder become invalidated
after the invocation of this method, and should be cleared (see clear)
if they are to be used again.
Also, combining two combiners c1 and c2 for which c1 eq c2 is true, that is,
they are the same objects in memory:
c1.combine(c2)
always does nothing and returns c1.
the type of elements contained by the other builder
the type of collection produced by the other builder
the other builder
the parallel builder containing both the elements of this and the other builder
Returns string formatted according to given format string.
Returns string formatted according to given format string.
Format strings are as for String.format
(@see java.lang.String.format).
Creates a new builder by applying a transformation function to the results of this builder.
Creates a new builder by applying a transformation function to the results of this builder.
the type of collection returned by f.
the transformation function.
a new builder which is the same as the current builder except that a transformation function is applied to this builder's result.
Produces a collection from the added elements.
Produces a collection from the added elements. The builder's contents are undefined after this operation.
a collection containing the elements added to this builder.
Constructs the result and sets the appropriate tasksupport object to the resulting collection if this is applicable.

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. However,
builder implementations are still required to work correctly even if the hint is
wrong, i.e. a different number of elements is added.
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 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.

the collection which serves as a hint for the result's size.
a correction to add to the coll.size to produce the size hint.

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.

the bounding collection. If it is an IndexedSeqLike, then sizes larger than collection's size are reduced.
An array combiner that uses doubling unrolled buffers to store elements.
