    Specified by:
    
    getValueClassName in interface DataLevelBucket
  - getOrder
```
public BucketOrder getOrder()
```
    Description copied from interface: DataLevelBucket
    Returns the bucket sorting type.
    The possible values are:
    
    BucketOrder.ASCENDING
    
    BucketOrder.DESCENDING
    
    BucketOrder.NONE
    Specified by:
    
    getOrder in interface DataLevelBucket
    
    Returns:
    
    the bucket sorting type

  - getExpression
```
public JRExpression getExpression()
```
    Description copied from interface: DataLevelBucket
    
    Returns the grouping expression.
    
    Specified by:
    
    getExpression in interface DataLevelBucket
    
    Returns:
    
    the grouping expression
  - getLabelExpression
```
public JRExpression getLabelExpression()
```
    Description copied from interface: DataLevelBucket
    
    Optional expression that provides labels for buckets.
    
    Specified by:
    
    getLabelExpression in interface DataLevelBucket
    
    Returns:
    
    the bucket label expression
  - getComparatorExpression
```
public JRExpression getComparatorExpression()
```
    Description copied from interface: DataLevelBucket
    
    Returns the comparator expression.
    The result of this expression is used to sort the buckets, in ascending or descending order (given by getOrder(). If the order type is BucketOrder.NONE, no sorting will be performed and the comparator expression will be ignored.
    
    If no comparator expression is specified, the natural order will be used.
    
    If the bucket has an order by expression, the comparator will be used to compare values as produced by that expression.
    
    Specified by:
    
    getComparatorExpression in interface DataLevelBucket
    
    Returns:
    
    the comparator expression
  - getValueClass
```
public Class<?> getValueClass()
```
    Description copied from interface: DataLevelBucket
    
    Returns the class of the bucket value. Any class is allowed as long as it is in the classpath at compile and run time.
    
    Specified by:
    
    getValueClass in interface DataLevelBucket
    
    Returns:
    
    a Class instance representing the bucket value class
