IloLinearNumExprIterator

All Superinterfaces:

java.util.Iterator
```
public interface IloLinearNumExprIterator
extends java.util.Iterator
```
This is the iterator for the linear terms of an IloLinearNumExpr expression object. The iterator allows the caller to enumerate all the terms of an IloLinearNumExpr and perform simple operations, such as querying or modifying a term. During the iteration, the caller can remove elements from the underlying IloLinearNumExpr using well-defined semantics.

Method Summary

Methods
Modifier and Type	Method and Description
`double`	`getValue()` Returns the coefficient related to the `IloNumVar` accessed by the last call to the method `next()`.
`IloNumVar`	`nextNumVar()` Returns the `IloNumVar` of the next linear term in the underlying `IloLinearNumExpr`.
`void`	`setNumVar(IloNumVar var)` Sets the `IloNumVar` of the last linear term in the scalar product.
`void`	`setValue(double value)` Sets the coefficient related to the `IloIntVar` accessed by the last call to the method `next()`.

- Method Detail
  - nextNumVar
```
IloNumVar nextNumVar()
```
    Returns the IloNumVar of the next linear term in the underlying IloLinearNumExpr. This differs from the method next() in that this method returns the variable with the correct java type, avoiding the need for a downcast.
    
    Throws:
    
    NoSuchElementException - The iteration has no more elements.
    
    Returns:
    The next IloNumVar in the iteration.
  - setNumVar
```
void setNumVar(IloNumVar var)
```
    Sets the IloNumVar of the last linear term in the scalar product.
    
    Throws:
    
    IllegalStateException - This occurs if the next() or the nextNumVar() method has not been called, or if the remove method has been called since the last call to the next() or the nextNumVar() method.
    Parameters:
    var - The variable to be set for the current linear term of the underlying IloLinearNumExpr.
  - getValue
```
double getValue()
```
    Returns the coefficient related to the IloNumVar accessed by the last call to the method next().
    
    Throws:
    
    IllegalStateException - This occurs if the next() or the nextNumVar() method has not been called, or if the remove method has been called since the last call to the next() or the nextNumVar() method.
    
    Returns:
    The coefficient of the current linear term.
  - setValue
```
void setValue(double value)
```
    Sets the coefficient related to the IloIntVar accessed by the last call to the method next().
    
    Throws:
    
    IllegalStateException - This occurs if the method next or nextNumVar has not been called, or if the remove method has been called since the last call to next or nextNumVar.
    Parameters:
    value - The coefficient value to be set for the current linear term of the underlying IloLinearNumExpr.
