Interface ResolveParameterHook

All Superinterfaces:

LifecycleHook

All Known Implementing Classes:

PerProperty.PerPropertyHook

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@API(status=MAINTAINED,
     since="1.4.0")
 @FunctionalInterface
public interface ResolveParameterHook
extends LifecycleHook

This hook type allows to provide parameters for property methods but also to annotated lifecycle methods.

Method Summary

Modifier and Type	Method and Description
java.util.Optional<ResolveParameterHook.ParameterSupplier>	resolve(ParameterResolutionContext parameterContext, LifecycleContext lifecycleContext) This method will be called only once per property, whereas the returned supplier's get method is usually invoked for each try - and potentially more often during shrinking or when resolving parameters in before/after methods.

resolve

java.util.Optional<ResolveParameterHook.ParameterSupplier> resolve(ParameterResolutionContext parameterContext,
                                                                   LifecycleContext lifecycleContext)

This method will be called only once per property, whereas the returned supplier's get method is usually invoked for each try - and potentially more often during shrinking or when resolving parameters in before/after methods. The returned supplier should always return an equivalent object, i.e. an object that behaves the same when used in the same way.

Parameters:

parameterContext - Contains information of parameter to resolve

lifecycleContext - Can be of type ContainerLifecycleContext or PropertyLifecycleContext

Returns:

supplier instance wrapped in Optional or Optional.empty() if it cannot be resolved
