- def addAll(xs: IterableOnce[Char]): ofChar.this.type
Adds all elements produced by an IterableOnce to this growable collection.
Adds all elements produced by an IterableOnce to this growable collection.
- xs
the IterableOnce producing the elements to add.
- returns
the growable collection itself.

- def addAll(xs: Array[_ <: Char], offset: Int, length: Int): ofChar.this.type
Add a slice of an array

- Definition Classes

- def addOne(elem: Char): ofChar.this.type
Adds a single element to this growable collection.
- 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.- Definition Classes

- def equals(other: Any): Boolean
The equality method for reference types.
- def knownSize: Int
- returns
The number of elements in the collection under construction, if it can be cheaply computed, -1 otherwise. The default implementation always returns -1.

- def result(): Array[Char]
Produces a collection from the added elements.
Produces a collection from the added elements.
After a call to

, the behavior of all other methods is undefined save forclear()
. Ifclear()
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.

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

a correction to add to the

Package structure
The scala package contains core types like
Int
,Float
,Array
orOption
which are accessible in all Scala compilation units without explicit qualification or imports.Notable packages include:
scala.collection
and its sub-packages contain Scala's collections frameworkscala.collection.immutable
- Immutable, sequential data-structures such asVector
,List
,Range
,HashMap
orHashSet
scala.collection.mutable
- Mutable, sequential data-structures such asArrayBuffer
,StringBuilder
,HashMap
orHashSet
scala.collection.concurrent
- Mutable, concurrent data-structures such asTrieMap
scala.concurrent
- Primitives for concurrent programming such asFutures
andPromises
scala.io
- Input and output operationsscala.math
- Basic math functions and additional numeric types likeBigInt
andBigDecimal
scala.sys
- Interaction with other processes and the operating systemscala.util.matching
- Regular expressionsOther packages exist. See the complete list on the right.
Additional parts of the standard library are shipped as separate libraries. These include:
scala.reflect
- Scala's reflection API (scala-reflect.jar)scala.xml
- XML parsing, manipulation, and serialization (scala-xml.jar)scala.collection.parallel
- Parallel collections (scala-parallel-collections.jar)scala.util.parsing
- Parser combinators (scala-parser-combinators.jar)scala.swing
- A convenient wrapper around Java's GUI framework called Swing (scala-swing.jar)Automatic imports
Identifiers in the scala package and the
scala.Predef
object are always in scope by default.Some of these identifiers are type aliases provided as shortcuts to commonly used classes. For example,
List
is an alias forscala.collection.immutable.List
.Other aliases refer to classes provided by the underlying platform. For example, on the JVM,
String
is an alias forjava.lang.String
.
