    • getErasedType

      public static Type getErasedType(Type type)
      Gets the erased type of the specified type.
      Parameters:

      Parameters:
      rawType - the raw type
      actualTypeArguments - the actual type arguments
      Returns:
      the parameterized type
      Throws:

      Type Parameters:
      A - the type of the annotation
      Parameters:
      annotationType - The annotation type.
      validators - List of constraint validator classes (for a given constraint).
      Returns:
      Return a Map<Class, Class<? extends ConstraintValidator>> where the map key is the type the validator accepts and value the validator class itself.
