org.springframework.data.util.ParameterTypes
Abstraction over a list of parameter value types. Allows to check whether a list of parameter values with the given
type setup is a candidate for the invocation of a given
Method
(see areValidFor(Method)
). This is
necessary to properly match parameter values against methods declaring varargs arguments. The implementation favors
direct matches and only computes the alternative sets of types to be considered if the primary one doesn't match.- Since:
