LinkedList (JADE v4.5.0 API)

java.lang.Object
- jade.util.leap.LinkedList

All Implemented Interfaces:

Collection, List, java.io.Serializable
```
public class LinkedList
extends java.lang.Object
implements List, Serializable
```
The LEAP (environment-dependent) version of the &qote;java.util.ArrayList&qote; class. This class appears to be exactly the same in J2SE, PJAVA and MIDP. The internal implementation is different in the three cases however.
