Detailed Description

Class provides run-time type information for objects in Hunny MIME++. All subclasses of Node contain a pointer to an instance of Class. You may call Node::class_() to obtain a reference to that instance.

The following code example shows how you can check the type of an object at run-time:

    void CheckType(Node* node) {
         if (node->class_().isA(mimepp::MESSAGE_CLASS)) {
             // ...
         }
         else if (node->class_().isA(mimepp::BODY_PART_CLASS)) {
             // ...
         }
     } 

The enumerated type IDs are listed in the mimepp.h header file.

Member Function Documentation

int id

(

)

const [inline]

Gets the class ID.

The enumerated type IDs are listed in the mimepp.h header file.

Returns:

ID of the class

const bool isA

(

const char *

name

)

const

Returns true if the object associated with this Class instance is of type name.

Parameters:

name

name of a class

const bool isA

(

int

id

)

const

Returns true if the object associated with this Class instance is of type id.

Parameters:

id

ID of a class

const char * name

(

)

const [inline]

Gets the class name.

Returns:

name of the class

const Class * superclass

(

)

const [inline]

Gets the Class instance associated with the superclass of a class.

This member function returns a pointer that may be NULL. (The pointer is NULL if there is no superclass.)

Returns:

superclass
