    • matches

      public boolean matches(Set<Type> requiredTypes, Set<Type> beanTypes)
      Description copied from interface: AssignabilityRules
      Check whether at least one of the requiredTypes matches a type in beanTypes
      Specified by:
      matches in interface AssignabilityRules
      Parameters:
      requiredTypes - the requiredTypes
      beanTypes - the beanTypes
      Returns:
      can we assign some type from requiredTypes to some type in beanTypes

    • matches

      public boolean matches(Type requiredType, Set<? extends Type> beanTypes)
      Description copied from interface: AssignabilityRules
      Check whether requiredType matches a type in beanTypes
      Specified by:
      matches in interface AssignabilityRules
      Parameters:
      requiredType - the requiredType
      beanTypes - the beanTypes
      Returns:
      can we assign requiredType to some type in beanTypes

    • boundsMatch

      protected boolean boundsMatch(Type[] upperBounds, Type[] stricterUpperBounds)
      Returns true iff for each upper bound T, there is at least one bound from stricterUpperBounds assignable to T. This reflects that stricterUpperBounds are at least as strict as upperBounds are.

      Arguments passed to this method must be legal java bounds, i.e. bounds returned by TypeVariable.getBounds(), WildcardType.getUpperBounds() or WildcardType.getLowerBounds().

    • lowerBoundsOfWildcardMatch

      protected boolean lowerBoundsOfWildcardMatch(Type parameter, WildcardType requiredParameter)

    • lowerBoundsOfWildcardMatch

      protected boolean lowerBoundsOfWildcardMatch(Type[] beanParameterBounds, WildcardType requiredParameter)

    • upperBoundsOfWildcardMatch

      protected boolean upperBoundsOfWildcardMatch(WildcardType requiredParameter, Type parameter)
