Inheritance diagram for DynPtr< Object, ObjectBase >:

List of all members.

Public Types

• typedef Object object_t

  Type of the associated object.
  

Public Member Functions

• const DynPtr & getDynPtr () const throw ()

  Convenience type cast to dynamic pointer class.
  

• const type_info & getType () const throw ()

  Return type info of associated object, typeid(NullPtr) or typeid(void) if none.
  

• bool isAssignable (const DynPtr< ObjectBase, ObjectBase > &Other) const throw ()

  Check whether a given pointer to a base class may be assigned to a pointer of the derived class.
  

• Object * rawptr () const throw ()
• void speak (const char *s, const char *prefix="") const throw ()

  Print some debug messages to the console.
  

Validity Operators

• operator void * () const throw ()

  Check if the pointer is valid.
  

• bool operator! () const throw ()

  Check if the pointer is invalid.
  

Static Public Member Functions

• static const DynPtr & getNullPtr () throw ()

  Associated static NullPtr - avoids creation of a temporary object when a reference is needed.

Detailed Description

template<class Object, class ObjectBase>
class DynPtr< Object, ObjectBase >

Encapsuled pointer class for pointers pointing to derived classes.

It performs a native dynamic_cast<> on assignment and construction and caches the result.

Member Function Documentation

template<class Object, class ObjectBase>

bool DynPtr< Object, ObjectBase >::isAssignable

(

const DynPtr< ObjectBase, ObjectBase > &

Other

)

const throw () [inline]

Check whether a given pointer to a base class may be assigned to a pointer of the derived class.

This function doesn't need to create a new pointer and is thus little lighter than pointer assignment, it basically just involves a dynamic_cast.

template<class Object, class ObjectBase>

DynPtr< Object, ObjectBase >::operator void *

(

)

const throw () [inline]

Check if the pointer is valid.

Note that the referred object might still exist, but not be of the appropriate type.

template<class Object, class ObjectBase>

bool DynPtr< Object, ObjectBase >::operator!

(

)

const throw () [inline]

Check if the pointer is invalid.

Note that the referred object might still exist, but not be of the appropriate type.
