suggestValueForVariable method
Suggest an updated value for the edit variable. The edit variable must already be added to the solver.
Suggestions update values of variables within the Solver but take into
account all the constraints already present in the Solver. Depending
on the constraints, the value of the Variable may not actually be the
value specified. The actual value can be read after the next
flushUpdates
call. Since these updates are merely "suggestions", they
cannot be at Priority.required
.
Check the Result returned to make sure the operation succeeded. Any
errors will be reported via the message
property on the Result.
Possible Results:
- Result.success: The suggestion was successfully applied to the variable within the solver.
- Result.unknownEditVariable: The edit variable was not already present
in the Solver. So the suggestion could not be applied. Add this edit
variable to the solver and then apply the value again. If you have
already added the variable to the Solver, make sure the Result
was
Result.success
.
Implementation
Result suggestValueForVariable(Variable variable, double value) {
if (!_edits.containsKey(variable)) {
return Result.unknownEditVariable;
}
_suggestValueForEditInfoWithoutDualOptimization(_edits[variable]!, value);
return _dualOptimize();
}
