clone

public java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

addAggregate

public void addAggregate(Aggregate aggregate)

Add an aggregate function to this grouping.

---

addSort

public void addSort(Sort sort)

Add a sort to this grouping.

---

addAggregate

public void addAggregate(java.lang.String attribute_name,
                         int type)

Add an aggregate function to this grouping. Equivalent to addAggregate(new Aggregate(attribute_name, type)).

---

addSort

public void addSort(java.lang.String attribute_name,
                    int direction)

Add a sort to this grouping. Equivalent to addSort(new Sort(attribute_name, direction)).

---

public org.jdaemon.util.QuickList getSorts()

Get a list of the Sorts implicit in this grouping.

---

getAggregates

public org.jdaemon.util.QuickList getAggregates()

Get a list of all the Aggregates in this grouping
