public abstract class AbstractFunction
- extends java.lang.Object
- implements Function
Base class for Function implementations. The default implementation of
multiMap() calls map(). This will be a little slower than if both methods
were to call a static function, so if multiMap speed is an issue this
method could be overridden, or it might be better not to use this abstract class.
