                                  ParameterMapper parameterMapper)

Creates a new {code ReflectiveOperationInvoker} that will invoke the given method on the given target. The given parameterMapper will be used to map parameters to the required types and the given parameterNameMapper will be used map parameters by name.

Parameters:

target - the target of the reflective call

method - the method to call

parameterMapper - the parameter mapper
