Galder Zamarreño commented on ISPN-5704:
----------------------------------------
Use case: we want to add an element to a List and the list is stored as V in the
functional map. You could try using this function:
{code}
<R> CompletableFuture<R> eval(K key, V value, BiFunction<V,
ReadWriteEntryView<K, V>, R> f)
{code}
But the problem is that the element to add to the list can't be passed in {{value}}
since V is List and not the individual element. Could we have a more flexible value type?
Could we have this?
{code}
<R, T> CompletableFuture<R> eval(K key, T value, BiFunction<T,
ReadWriteEntryView<K, V>, R> f)
{code}
The problem then would be that we could not call {{view.set(value)}}... It needs some
thought.
Enhancements for Functional Map API
-----------------------------------
Key: ISPN-5704
URL:
https://issues.jboss.org/browse/ISPN-5704
Project: Infinispan
Issue Type: Enhancement
Reporter: Galder Zamarreño
Assignee: Galder Zamarreño
Fix For: 8.1.0.Final
List of enhancements that didn't make it into 8.0:
* Transaction support.
* Verify locks are acquired for all operations (once tx is in place, locks can be checked
easily)
* Complete persistence support (remove many returning previous, put many returning
previous, remove many)
* Replication of per-invocation parameters.
* Port mode *Becoming*Test to functional APIs, and expand on testing other functional
APIs.
* Test interoperability with cache, e.g. cache put with lifespan can be retrieved via
functional map with lifespan, and viceversa
* Test compatibility mode
* Add more listener events: activation, passivation and expiration.
* Use check isLocal instead of `e == null` in command impls
* Fix branch skip issue (see previous PR:
https://github.com/infinispan/infinispan/pull/3571)
* Add externalizers for primitive versions of Optional.
* ValueMatcherMode indexes in MarshallableFunctionExternalizers should be based on
{{ordinal()}} calls to annotation. Also, could the core's enumeration use the
annotations defined in commons?
* Add AdvancedExternalizer version for functions that takes value matcher
