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

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.

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

The following one way conversion is provided via asScala:
