公共类IloCPEngine
扩展java.lang.Object

该类的实例表示 CP Optimizer 的回溯搜索引擎。

您永远不需要创建该类的实例。主 "IloCP对象将创建该类的实例，如果您需要定义IloCustomXXX类的子类，可以在自己的 CP Optimizer 扩展代码中使用这些实例。

修饰符和类型	方法和说明
`int`	`getDomainSize(IloNumVar var)` This member function returns the size of the domain of variable `var` as maintained in the invoking instance of `IloCPEngine`.
`ilog.cp.cppimpl.IloCPEngine`	`getImpl()`
`int`	`getInfo(IloCPEngine.IntInfo which)` This method returns the value of the integer information `which` in the invoked `IloCPEngine` instance.
`IloCP`	`getMasterCP()` This method returns the master `IloCP` class which created the invoking `IloCPEngine` object.
`double`	`getMax(IloNumVar var)` This member function returns the maximum value of the variable `var` in the invoking instance of `IloCPEngine`.
`double`	`getMin(IloNumVar var)` This member function returns the minimum value of the variable `var` in the invoking instance of `IloCPEngine`.
`boolean`	`isFixed(IloNumVar var)` 该成员函数指示 "`var`的域是否具有由调用的 "`IloCPEngine`实例维护的特定值。
`boolean`	`isInDomain(IloNumVar var, int value)` This member function indicates whether `value` is contained in the current domain of `var` as maintained by the invoking `IloCPEngine` instance.
`java.util.Iterator`	`iterator(IloIntVar var)` 该成员函数返回一个迭代器，用于遍历由调用IloCPEngine 维护的 "`var`域。

  - getImpl
```
public ilogilog.cp.cppimpl.IloCPEngine getImpl()
```
  - getMasterCP
```
公共IloCP getMasterCP()
```
    This method returns the master IloCP class which created the invoking IloCPEngine object.
  - getMin
```
public double getMin(IloNumVarvar)
```
    This member function returns the minimum value of the variable var in the invoking instance of IloCPEngine.
  - getMax
```
public double getMax(IloNumVarvar)
```
    This member function returns the maximum value of the variable var in the invoking instance of IloCPEngine.
  - isInDomain
```
public boolean isInDomain(IloNumVarvar、
                 int value)
```
    This member function indicates whether value is contained in the current domain of var as maintained by the invoking IloCPEngine instance. 如果 "var不是积分类型，则违反了断言。
  - getDomainSize
```
public int getDomainSize(IloNumVarvar)
```
    This member function returns the size of the domain of variable var as maintained in the invoking instance of IloCPEngine. 如果 "var不是积分类型，则违反了断言。
  - isFixed
```
public boolean isFixed(IloNumVarvar)
```
    该成员函数指示 "var的域是否具有由调用的 "IloCPEngine实例维护的特定值。
  - 迭代器
```
publicjava.util.IteratoriteratorIloIntVarvar)
```
    该成员函数返回一个迭代器，用于遍历由调用IloCPEngine 维护的 "var域。
  - getInfo
```
public int getInfo(IloCPEngine.IntInfowhich)
            抛出IloException
```
    This method returns the value of the integer information which in the invoked IloCPEngine instance. 这些信息是关于该本地工人的，而不是整个搜索过程的。
    
    抛出：
    
    IloException
