IntVarLocalSearchOperator (com.google.ortools:ortools-java 9.12.9999 API)

java.lang.Object
- com.google.ortools.constraintsolver.BaseObject
- - com.google.ortools.constraintsolver.LocalSearchOperator
  - - com.google.ortools.constraintsolver.IntVarLocalSearchOperator

Direct Known Subclasses:

BaseLns, ChangeValue
```
public class IntVarLocalSearchOperator
extends LocalSearchOperator
```
Specialization of LocalSearchOperator built from an array of IntVars
which specifies the scope of the operator.
This class also takes care of storing current variable values in Start(),
keeps track of changes done by the operator and builds the delta.
The Deactivate() method can be used to perform Large Neighborhood Search.

  This method should not be overridden. Override OnStart() instead which is
  called before exiting this method.
  
  Overrides:
  
  start in class LocalSearchOperator

```
  Returns the variable of given index.
- SkipUnchanged
```
public boolean SkipUnchanged(int arg0)
```
- oldValue

public void RevertChanges(boolean change_was_incremental)
```
- addVars
```
public void addVars(IntVar[] vars)
```
- onStart
```
public void onStart()
```
  Called by Start() after synchronizing the operator with the current
  assignment. Should be overridden instead of Start() to avoid calling
  IntVarLocalSearchOperator::Start explicitly.
- oneNeighbor
```
protected boolean oneNeighbor()
```
  Creates a new neighbor. It returns false when the neighborhood is
  completely explored.
  MakeNextNeighbor() in a subclass of IntVarLocalSearchOperator.
