- Method Detail
  - getValueClassName
```
public String getValueClassName()
```
    Description copied from interface: JRCrosstabBucket
    
    Returns the string name of the bucket value class.
    
    Specified by:
    
    getValueClassName in interface JRCrosstabBucket
  - getOrder
```
public BucketOrder getOrder()
```
    Description copied from interface: JRCrosstabBucket
    Returns the bucket sorting type.
    The possible values are:
    
    BucketOrder.ASCENDING
    
    BucketOrder.DESCENDING
    
    BucketOrder.NONE
    Specified by:
    
    getOrder in interface JRCrosstabBucket
    
    Returns:
    
    the bucket sorting type

  - getExpression
```
public JRExpression getExpression()
```
    Description copied from interface: JRCrosstabBucket
    
    Returns the grouping expression.
    
    Specified by:
    
    getExpression in interface JRCrosstabBucket
    
    Returns:
    
    the grouping expression
  - getOrderByExpression
```
public JRExpression getOrderByExpression()
```
    Description copied from interface: JRCrosstabBucket
    
    Returns an expression that provides order by values for group buckets. If not set, the bucket values as returned by JRCrosstabBucket.getExpression() are used to order the buckets.
    The expression is evaluated in the context of the crosstab group and can reference measure variables, which evaluate to group totals.
    
    Specified by:
    
    getOrderByExpression in interface JRCrosstabBucket
    
    Returns:
    
    the order by value expression for the group bucket
  - getComparatorExpression
```
public JRExpression getComparatorExpression()
```
    Description copied from interface: JRCrosstabBucket
    
    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 bucket has an order by expression, the comparator will be used to compare values as produced by that expression. If no comparator expression is specified, the natural order will be used.
    
    Specified by:
    
    getComparatorExpression in interface JRCrosstabBucket
    
    Returns:
    
    the comparator expression

    JRCrosstabBucket.getOrderByExpression()
  - getValueClass
```
public Class<?> getValueClass()
```
    Description copied from interface: JRCrosstabBucket
    
    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 JRCrosstabBucket
    
    Returns:
    
    a Class instance representing the bucket value class
  - clone
```
public Object clone()
```
    Specified by:
    
    clone in interface JRCloneable
    
    Overrides:
