invoke

public <T> T invoke(Constructor<T> constructor,
 Optional<Object> outerInstance,
 ExtensionContext extensionContext,

This method should only be used to invoke the constructor for an inner class.

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(Method method,
 Object target,
 ExtensionContext extensionContext,
 ExtensionRegistry extensionRegistry,
 ExecutableInvoker.ReflectiveInterceptorCall<Method,T> interceptorCall)

Invoke the supplied static method with dynamic parameter resolution.

Parameters:

method - the method to invoke and resolve parameters for

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

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