Class ParameterTypes

java.lang.Object
org.springframework.data.util.ParameterTypes
public class ParameterTypes extends Object
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.

      public static ParameterTypes of(List<TypeDescriptor> types)
      Returns the ParameterTypes for the given list of TypeDescriptors.
      Parameters:
      types - must not be null.
      Returns:

    • areValidFor

      public boolean areValidFor(Method method)
      Returns whether the parameter types are valid for the given Method. That means, a parameter value list with the given type arrangement is a valid list to invoke the given method.
      Parameters:
      method - must not be null.
      Returns:

    • exactlyMatchParametersOf

      public boolean exactlyMatchParametersOf(Method method)
      Returns whether the current parameter types match the given Method's parameters exactly, i.e. they're equal, not only assignable.
      Parameters:
      method - must not be null.
      Returns:
