Class SoftServiceLoader.StaticDefinition<S>

java.lang.Object

io.micronaut.core.io.service.SoftServiceLoader.StaticDefinition<S>

Type Parameters:

S - The service type

All Implemented Interfaces:

ServiceDefinition<S>

Enclosing class:

SoftServiceLoader<S>

public static final class SoftServiceLoader.StaticDefinition<S>
extends Object
implements ServiceDefinition<S>

A ServiceDefinition implementation that creates instances using the same instantiation strategy as SoftServiceLoader.instantiate(Class): it first attempts to invoke a no-argument constructor via a MethodHandles.Lookup method handle, and if that fails due to access restrictions or similar conditions, it falls back to reflective instantiation using

invalid reference

java.lang.Class#getDeclaredConstructor()

. Depending on module and security configuration, this may allow invoking non-public no-argument constructors.
