    Returns:
    a string containing the variable name
  - getValueClass
```
public Class<?> getValueClass()
```
    Description copied from interface: JRVariable
    
    Returns the class of the variable value. Any class is allowed as long as it is in the classpath at compile and run time.
    
    Specified by:
    
    getValueClass in interface JRVariable
    
    Returns:
    a Class instance representing the variable value class
  - getValueClassName
```

```
    Description copied from interface: JRVariable
    
    Returns the string name of the variable value class.
    
    Specified by:
    
    getValueClassName in interface JRVariable
  - getIncrementerFactoryClass
```
public Class<?> getIncrementerFactoryClass()

```
    Description copied from interface: JRVariable
    
    Gets the variable reset type.
    
    Specified by:
    
    getResetTypeValue in interface JRVariable
    
    Returns:
    a value representing one of the reset type constants in ResetTypeEnum
  - getIncrementTypeValue
```
public IncrementTypeEnum getIncrementTypeValue()
```
    Description copied from interface: JRVariable
    
    Gets the variable increment type.

    CalculationEnum.SYSTEM
  - getExpression
```
public JRExpression getExpression()
```
    Description copied from interface: JRVariable
