Detailed Description
The undelta class is used to store undo information in the work nodes. It is designed as a wrapper class in order to overcome the problem that copy constructors cannot be overloaded.Definition at line 223 of file api_deltabase.h.
Constructor & Destructor Documentation
| coco::undelta::undelta | ( | ) | [inline] |
Standard Constructor
Definition at line 231 of file api_deltabase.h.
| coco::undelta::undelta | ( | undelta_base * | __d | ) | [inline] |
Internal Constructor, which just copies the pointer to the undelta_base. This pointer must be allocated by new, since it will be removed with delete in the destructor
Definition at line 235 of file api_deltabase.h.
| coco::undelta::undelta | ( | const undelta & | __d | ) | [inline] |
Copy Constructor, which constructs a new undelta from an existing undelta. The clone operation for the undelta_base will be called in that process, effectively overloading the copy constructor for the undelta_base.
Definition at line 197 of file api_delta.h.
| coco::undelta::~undelta | ( | ) | [inline] |
Destructor, which frees the _d using delete
Definition at line 203 of file api_delta.h.
Member Function Documentation
| const undelta_base * coco::undelta::get_base | ( | ) | const [inline] |
Return the undelta_base stored in this wrapper
Definition at line 218 of file api_delta.h.
Assignment operator, which uses the clone operation for the undelta_base, effectively overloading the assignment operator for the undelta_base.
Definition at line 209 of file api_delta.h.
Undo the delta with delta_id _i in work node _x
Definition at line 220 of file api_delta.h.
| bool coco::undelta::unapply3 | ( | work_node & | _x, | |
| const work_node & | _y, | |||
| const delta_id & | _i | |||
| ) | const [inline] |
Undo the delta with delta_id _d in work node _x, constructing in the process work_node _y, without changing _x.
