Package io.quarkus.caffeine.runtime.graal

Class CacheConstructorsFeature

java.lang.Object

io.quarkus.caffeine.runtime.graal.CacheConstructorsFeature

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public class CacheConstructorsFeature
extends Object
implements org.graalvm.nativeimage.hosted.Feature

This Automatic Feature for GraalVM will register for reflection the most commonly used cache implementations from Caffeine. It's implemented as an explicit @Feature rather than using the Quarkus builditems because it doesn't need to be dynamically tuned (the list is static), and to take advantage of the reachability information we can infer from @Feature.DuringAnalysisAccess. This allows us to register for reflection these resources only if Caffeine is indeed being used: only if the cache builder is reachable in the application code.

This list is not complete, but a selection of the types we expect being most useful. unfortunately registering all of them has been shown to have a very significant impact on executable sizes. See https://github.com/quarkusio/quarkus/issues/12961
