ResolveParameterHook (documentation 1.3.9 API)

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=EXPERIMENTAL,
     since="1.2.4")
@FunctionalInterface
public interface ResolveParameterHook
extends LifecycleHook
```
This hook type allows to provide parameters for property methods but also to annotated lifecycle methods.

Modifier and Type	Method	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.

@API(status=EXPERIMENTAL,

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
