resolveParameters

public static java.lang.Object[] resolveParameters(java.lang.reflect.Method method,
                                                   java.util.Optional<java.lang.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 java.lang.Object[] resolveParameters(java.lang.reflect.Executable executable,
                                                   java.util.Optional<java.lang.Object> target,
                                                   java.util.Optional<java.lang.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
