Constructor Details

ResolverFacade

private ResolverFacade(AnnotatedElement sourceElement,
 NavigableMap<Integer, ? extends ResolverFacade.ResolvableParameterDeclaration> indexedParameters,
 Set<? extends ResolverFacade.ResolvableParameterDeclaration> aggregatorParameters,
 int parameterIndexOffset,
 ResolverFacade.RequiredParameterCount requiredParameterCount)

Method Details

create

static ResolverFacade create(Class<?> clazz,
 List<Field> fields)

create

static ResolverFacade create(Constructor<?> constructor,
 ParameterizedClass annotation)

create

static ResolverFacade create(Method method,
 Annotation annotation)

create

private static ResolverFacade create(Executable executable,
 Annotation annotation,
 int indexOffset)

Create a new ResolverFacade for the supplied Executable.

This method takes a best-effort approach at enforcing the following policy for parameterized class constructors and parameterized test methods that accept aggregators as arguments.

1. zero or more indexed arguments come first.
2. zero or more aggregators come next.
3. zero or more arguments supplied by other ParameterResolver implementations come last.

getIndexedParameterDeclarations

ParameterDeclarations getIndexedParameterDeclarations()

getRequiredParameterCount

ResolverFacade.RequiredParameterCount getRequiredParameterCount()

isSupportedParameter

boolean isSupportedParameter(org.junit.jupiter.api.extension.ParameterContext parameterContext,
 EvaluatedArgumentSet arguments)

getParameterName

Optional<String> getParameterName(int parameterIndex)

Get the name of the parameter with the supplied index, if it is present and declared before the aggregators.

Returns:

an Optional containing the name of the parameter

determineConsumedArgumentLength

int determineConsumedArgumentLength(int totalLength)

Determine the length of the arguments array that is considered consumed by the parameter declarations in this resolver.

If an aggregator is present, all arguments are considered consumed. Otherwise, the consumed argument length is the minimum of the total length and the number of indexed parameter declarations.

determineConsumedArgumentCount

int determineConsumedArgumentCount(EvaluatedArgumentSet arguments)

Determine the number of arguments that are considered consumed by the parameter declarations in this resolver.

If an aggregator is present, all arguments are considered consumed. Otherwise, the consumed argument count, is the number of indexes that correspond to indexed parameter declarations.

createLifecycleMethodParameterResolver

ArgumentSetLifecycleMethod.ParameterResolver createLifecycleMethodParameterResolver(Method method,
 Annotation annotation)

resolve

Object resolve(org.junit.jupiter.api.extension.ParameterContext parameterContext,
