FunctionConverters

object FunctionConverters

This object contains methods that convert between Scala and Java function types.

The explicit conversion methods defined here are intended to be used in Java code. For Scala code, it is recommended to use the extension methods defined in scala.jdk.FunctionConverters.

For details how the function converters work, see scala.jdk.FunctionConverters.
