Parameters:

constructor - the constructor to invoke and resolve parameters for

extensionContext - the current ExtensionContext

extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from

invoke

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

Parameters:

constructor - the constructor to invoke and resolve parameters for

outerInstance - the outer instance to supply as the first argument to the constructor

extensionContext - the current ExtensionContext

invoke

public Object invoke(Method method,
                     ExtensionContext extensionContext,
                     ExtensionRegistry extensionRegistry)

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

invoke

public Object invoke(Method method,
                     Object target,
                     ExtensionContext extensionContext,
                     ExtensionRegistry extensionRegistry)

Invoke the supplied method on the supplied target object with dynamic parameter resolution.

Parameters:

method - the method to invoke and resolve parameters for

target - the object on which the method will be invoked; should be null for static methods
