Package org.tweetyproject.arg.adf.transform

Class AbstractCollector<U,D,R>

java.lang.Object

org.tweetyproject.arg.adf.transform.AbstractCollector<U,D,R>

Type Parameters:

U - the type of the additional result the collector may provide

D - the type of the objects we want to collect

R - the result of the transformation

All Implemented Interfaces:

Collector<U,D>, Transformer<R>

public abstract class AbstractCollector<U,D,R>
extends Object
implements Transformer<R>, Collector<U,D>

Similar to AbstractTransformer but is designed for collections and therefore provides Collector functionality for free.
