Class Match<In,Out>

java.lang.Object

org.kie.workbench.common.stunner.bpmn.client.marshall.converters.Match<In,Out>

Type Parameters:

In - the input type of the match

Out - the type of the result of the match

public class Match<In,Out>
extends Object

Creates a pattern matching function.

Example usage:

     // let be T1 a class, and let be T1a, T1b subclasses of T1
     // then, let be T2 a class, and let be T2a, T2b subclasses of T2
     // such that T1a corresponds to T2a, T1b corresponds to T2b:
     Match m =
         Match.of(T1.class, T2.class)
           .when(T1a.class, t1aInstance -> ... create an equivalent t2a instance)
           .when(T1b.class, t1bInstance -> ... create an equivalent t2b instance)
     T1 myT1 = ...;

     Result result = myT1.apply(myT1);
     // unwrap the result on success, raise an exception otherwise
     T2 t2 = result.value();
