Type Members
- class BeanProperty extends Annotation with StaticAnnotation
When attached to a field, this annotation adds a setter and a getter method following the Java Bean convention.
When attached to a field, this annotation adds a setter and a getter method following the Java Bean convention. For example:
@BeanProperty var status = ""
adds the following methods to the class:
def setStatus(s: String): Unit = { this.status = s } def getStatus(): String = this.status
For fields of type
Boolean
, if you need a getter namedisStatus
, use thescala.beans.BooleanBeanProperty
annotation instead.- Annotations
- @field() @beanGetter() @beanSetter() @deprecatedInheritance()
- class BooleanBeanProperty extends Annotation with StaticAnnotation
This annotation has the same functionality as
scala.beans.BeanProperty
, but the generated Bean getter will be namedisFieldName
instead ofgetFieldName

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
.
