Note: This documentation is automatically generated.
| Method |
Activate | Return type: void Arguments: int64_t index |
Activated | Return type: bool Arguments: int64_t index |
AddVars | Return type: void Arguments: const std::vector<V*>& vars |
ApplyChanges | Return type: bool Arguments: Assignment* delta, Assignment* deltadelta |
Deactivate | Return type: void Arguments: int64_t index |
HoldsDelta | Return type: bool |
IsIncremental | Return type: virtual bool |
OldValue | Return type: const Val& Arguments: int64_t index |
OnStart | Return type: virtual void Called by Start() after synchronizing the operator with the current
assignment. Should be overridden instead of Start() to avoid calling
VarLocalSearchOperator::Start explicitly.
|
RevertChanges | Return type: void Arguments: bool incremental |
SetValue | Return type: void Arguments: int64_t index, const Val& value |
Size | Return type: int |
SkipUnchanged | Return type: virtual bool Arguments: int index |
Start | Return type: void Arguments: const Assignment* assignment This method should not be overridden. Override OnStart() instead which is
called before exiting this method.
|
Value | Return type: const Val& Arguments: int64_t index Returns the value in the current assignment of the variable of given
index.
|
Var | Return type: V* Arguments: int64_t index Returns the variable of given index.
