A named string holding a pointer to arbitrary data. The pointer is owned by the object: it will be released when the object is destroyed or the string value changed
explicit NamedPointer (const char* name, GenObject* data = 0, const char* value = 0)
| NamedPointer |
Creates a new named pointer
Parameters:
name | Name of this pointer |
data | Initial pointer value. The pointer will be owned by this object |
value | Initial string value |
~NamedPointer ()
| ~NamedPointer |
[virtual]
Destructor. Release the pointer
inline GenObject* userData ()
| userData |
[const]
Retrieve the pointer carried by this object
Returns: Pointer to arbitrary user GenObject
GenObject* takeData ()
| takeData |
Retrieve the pointer carried by this object and release ownership. The caller will own the returned pointer
Returns: Pointer to arbitrary user GenObject
void userData (GenObject* data)
| userData |
Set obscure data carried by this object. Note that a RefObject's reference counter should be increased before adding it to this named pointer
Parameters:
data | Pointer to arbitrary user data |
inline void* userObject (const String& name)
| userObject |
[const]
Get a pointer to a derived class of user data given that class name
Parameters:
name | Name of the class we are asking for |
Returns: Pointer to the requested class or NULL if user object id NULL or doesn't implement it
inline NamedPointer& operator= (const char* value)
| operator= |
String value assignment operator
Reimplemented from NamedString.
void* getObject (const String& name)
| getObject |
[const virtual]
Get a pointer to a derived class given that class name
Parameters:
name | Name of the class we are asking for |
Returns: Pointer to the requested class or NULL if this object doesn't implement it
Reimplemented from NamedString.
void changed ()
| changed |
[protected virtual]
Called whenever the string value changed. Release the pointer
Reimplemented from String.
