Method Details

resolveParameters

public static @Nullable Object[] resolveParameters(Method method,
 Optional<Object> target,
 ExtensionContext extensionContext,
 ExtensionRegistry extensionRegistry)

Resolve the array of parameters for the supplied method and target.

Parameters:

method - the method for which to resolve parameters

target - an Optional containing the target on which the executable will be invoked; never null but should be empty for static methods and constructors

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

Returns:

the array of Objects to be used as parameters in the executable invocation; never null though potentially empty

resolveParameters

public static @Nullable Object[] resolveParameters(Executable executable,
 Optional<Object> target,
 Optional<Object> outerInstance,
 ExtensionContext extensionContext,
 ExtensionRegistry extensionRegistry)

Resolve the array of parameters for the supplied executable, target, and outer instance.

Parameters:

executable - the executable for which to resolve parameters

target - an Optional containing the target on which the executable will be invoked; never null but should be empty for static methods and constructors

outerInstance - the outer instance that will be supplied as the first argument to a constructor for an inner class; should be null for methods and constructors for top-level or static classes

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

Returns:

the array of Objects to be used as parameters in the executable invocation; never null though potentially empty
