Method Detail

invoke

public <T> T invoke(java.lang.reflect.Constructor<T> constructor,
                    java.util.Optional<java.lang.Object> outerInstance,
                    ExtensionContext extensionContext,
                    ExtensionRegistry extensionRegistry,
                    InterceptingExecutableInvoker.ReflectiveInterceptorCall<java.lang.reflect.Constructor<T>,T> interceptorCall)

Invoke the supplied constructor with the supplied outer instance and dynamic parameter resolution.

Parameters:

constructor - the constructor to invoke and resolve parameters for

outerInstance - the outer instance to supply as the first argument to the constructor; empty, for top-level classes

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

interceptorCall - the call for intercepting this constructor invocation via all registered interceptors

invoke

public <T> T invoke(java.lang.reflect.Method method,
                    java.lang.Object target,
                    ExtensionContext extensionContext,
                    ExtensionRegistry extensionRegistry,
                    InterceptingExecutableInvoker.ReflectiveInterceptorCall<java.lang.reflect.Method,T> interceptorCall)

Invoke the supplied method with dynamic parameter resolution.

Parameters:

method - the method to invoke and resolve parameters for

target - the target on which the executable will be invoked, potentially wrapped in an Optional; can be null or an empty Optional for a static method

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

interceptorCall - the call for intercepting this method invocation via all registered interceptors
