Class CacheConstructorsAutofeature

java.lang.Object

io.quarkus.caffeine.runtime.graal.CacheConstructorsAutofeature

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public class CacheConstructorsAutofeature
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.
