Interface RightComposingComputation.RightComposer<Key1,Result1,RightKey extends ComputeKey<?>,RightResult extends ComputeResult>

Type Parameters:

Key1 - the left computation key

Result1 - the left computation result

RightKey - the key of the right ComposedComputation

RightResult - the result of the right ComposedComputation

All Superinterfaces:

Composer<Key1,Result1>

Enclosing class:

RightComposingComputation<KeyIntermediate extends ComputeKey<?>,Key1 extends ComputeKey<Result1>,Result1 extends ComputeResult,Key2 extends ComputeKey<Result2>,Result2 extends ComputeResult>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface RightComposingComputation.RightComposer<Key1,Result1,RightKey extends ComputeKey<?>,RightResult extends ComputeResult>
extends Composer<Key1,Result1>

Specific Composer that the right computation is a ComposedComputation

                                                                                         Result1 result)
                                                                                  throws Exception

Specified by:

transitionWith in interface Composer<Key1,Result1>

Parameters:

key - the key from the base computation

result - the result corresponding to the key of the base computation

Returns:

the set of dependencies of the composed transformation given the key and result from the base computation

Throws:

Exception - as appropriate when computing dependencies.
