ImmutableBuilder
Reusable builder for immutable collections
- Source:
- ImmutableBuilder.scala
Value members
Concrete methods
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.
- Source:
- ImmutableBuilder.scala
- 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

- ImmutableBuilder.scala
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.
- Returns:
a collection containing the elements added to this builder.

Inherited methods
Adds all elements produced by an IterableOnce to this growable collection.
Adds all elements produced by an IterableOnce to this growable collection.
- Value parameters:
- xs
the IterableOnce producing the elements to add.
- Returns:
the growable collection itself.
- Inherited from:
- Growable
- Source:
- Growable.scala
Adds a single element to this growable collection.
Adds a single element to this growable collection.
- Value parameters:
- elem
the element to add.
- Returns:
the growable collection itself

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.
- Value parameters:
- coll
the collection which serves as a hint for the result's size.
- delta
a correction to add to the
coll.sizeto produce the size hint.

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, together with an upper bound
given by the size of some other collection.

- 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.

Deprecated and Inherited methods
Adds two or more elements to this growable collection.
Adds two or more elements to this growable collection.
- Value parameters:
- elem1
the first element to add.
- elem2
the second element to add.
- elems
the remaining elements to add.
