Detailed Description
Manages the recalculations of cells containing a formula.
The recalculations of a cell region, a sheet or the map are based on the following principle:
A cell could refer to other cells, which need to be recalculated before. The order of recalculation is determined by the depth of references, i.e. first the cells, which do not refer to other cells, are recalculated. Cells referring to those are next. Then cells, which refer to the ones in the last step follow and so on until all cells have been updated.
Cell value changes are blocked while doing this, i.e. they do not trigger a new recalculation event.

Member Function Documentation
| void RecalcManager::dump | ( | ) | const |
Prints out the cell depths in the current recalculation event.
Definition at line 259 of file RecalcManager.cpp.
| bool RecalcManager::isActive | ( | ) | const |
Returns the recalculation state.
- Returns:
true, if recalculations are in progress
Definition at line 214 of file RecalcManager.cpp.
| void RecalcManager::recalc | ( | ) | [protected] |
Iterates over the map of cell with their reference depths and calls recalcCell().
- See also:
- recalcCell()
Definition at line 219 of file RecalcManager.cpp.
| void RecalcManager::recalcMap | ( | ) |
Recalculates the whole map.
The cells are recalculated sorted by the reference depth in ascending order.
- See also:
- recalc()
Definition at line 203 of file RecalcManager.cpp.
| void RecalcManager::recalcSheet | ( | Sheet *const | sheet | ) |
Recalculates the sheet sheet .
The cells are recalculated sorted by the reference depth in ascending order.
- See also:
- recalc()
Definition at line 192 of file RecalcManager.cpp.
| void RecalcManager::regionChanged | ( | const Region & | region | ) |
Recalculates the cells referring to cells in region .
The cells are recalculated sorted by the reference depth in ascending order.
- See also:
- recalc()
