package pattern
This package is used as a collection point for usage patterns which involve actors, futures, etc.
Commonly Used Patterns With Akka
This package is used as a collection point for usage patterns which involve actors, futures, etc. but are loosely enough coupled to (multiple of) them to present them separately from the core implementation. Currently supported are:
- ask: create a temporary one-off actor for receiving a reply to a message and complete a scala.concurrent.Future with it; returns said Future.
- pipeTo: feed eventually computed value of a future to an org.apache.pekko.actor.ActorRef as a message.
- pipeToSelection: feed eventually computed value of a future to an org.apache.pekko.actor.ActorSelection as a message.
In Scala the recommended usage is to import the pattern from the package object:
```
import org.apache.pekko.pattern.ask

ask(actor, message) // use it directly
actor ask message   // use it by implicit conversion
```
For Java the patterns are available as static methods of the org.apache.pekko.pattern.Patterns class:
```
import static org.apache.pekko.pattern.Patterns.ask;

ask(actor, message);
```

def require(libraryName: String, requiredVersion: String): Unit
Check that the version of Pekko is a specific patch version or higher and throw an UnsupportedPekkoVersion exception if the version requirement is not fulfilled.
Check that the version of Pekko is a specific patch version or higher and throw an UnsupportedPekkoVersion exception if the version requirement is not fulfilled.
For example: require("my-library", "2.5.4") would fail if used with Pekko 2.4.19 and 2.5.3, but succeed with 2.5.4 and 2.6.1
libraryName
The name of the library or component requiring the Pekko version, used in the error message.
requiredVersion
Minimal version that this library works with
