Class LongList

java.lang.Object
  org.pentaho.reporting.engine.classic.core.util.LongList

All Implemented Interfaces:

Serializable, Cloneable

public class LongList
extends Object
implements Serializable, Cloneable

A Array-List for integer objects. Ints can be added to the list and will be stored in an int-array.

Using this list for storing ints is much faster than creating java.lang.Long objects and storing them in an ArrayList.

This list is not synchronized and does not implement the full List interface. In fact, this list can only be used to add new values or to clear the complete list.
