Type Members

trait DecorateAsJava extends AnyRef

A collection of decorators that allow converting between Scala and Java collections using asScala and asJava methods.

The following conversions are supported via asJava , asScala

• scala.collection.Iterable <=> java.lang.Iterable
• scala.collection.Iterator <=> java.util.Iterator
• scala.collection.mutable.Buffer <=> java.util.List
• scala.collection.mutable.Set <=> java.util.Set
• scala.collection.mutable.Map <=> java.util.Map
• scala.collection.mutable.concurrent.Map <=> java.util.concurrent.ConcurrentMap

In all cases, converting from a source type to a target type and back again will return the original source object, e.g.

import scala.collection.JavaConverters._

val sl = new scala.collection.mutable.ListBuffer[Int]
val jl : java.util.List[Int] = sl.asJava
val sl2 : scala.collection.mutable.Buffer[Int] = jl.asScala
assert(sl eq sl2)

The following conversions are also supported, but the direction from Scala to Java is done by the more specifically named methods: asJavaCollection , asJavaEnumeration , asJavaDictionary .

• scala.collection.Iterable <=> java.util.Collection
• scala.collection.Iterator <=> java.util.Enumeration
• scala.collection.mutable.Map <=> java.util.Dictionary

In addition, the following one way conversions are provided via asJava :

• scala.collection.Seq => java.util.List
• scala.collection.mutable.Seq => java.util.List
• scala.collection.Set => java.util.Set
• scala.collection.Map => java.util.Map

The following one way conversion is provided via asScala :

• java.util.Properties => scala.collection.mutable.Map
