 org.drools.reteoo.ObjectSinkNodeList
| ObjectSinkNodeList | | public class ObjectSinkNodeList implements Serializable(Code) | | This is a simple linked linked implementation. Each node must implement LinkedListNode so that it references
the node before and after it. This way a node can be removed without having to scan the list to find it. This class
does not provide an Iterator implementation as its designed for efficiency and not genericity. There are a number of
ways to iterate the list.
Simple iterator:
for ( LinkedListNode node = list.getFirst(); node != null; node = node.getNext() ) {
}
Iterator that pops the first entry:
for ( LinkedListNode node = list.removeFirst(); node != null; node = list.removeFirst() ) {
}

| ObjectSinkNodeList | | public ObjectSinkNodeList()(Code) | | Construct an empty LinkedList
|
| add | | public void add(ObjectSinkNode node)(Code) | | Add a ObjectSinkNode to the list. If the LinkedList is empty then the first and
last nodes are set to the added node.
Parameters:
node - The ObjectSinkNode to be added |
| clear | | public void clear()(Code) | | Iterates the list removing all the nodes until there are no more nodes to remove.
|
| getFirst | | final public ObjectSinkNode getFirst()(Code) | | Return the first node in the list
The first ObjectSinkNode. |
| getLast | | final public ObjectSinkNode getLast()(Code) | | Return the last node in the list
The last ObjectSinkNode. |
| isEmpty | | final public boolean isEmpty()(Code) | | boolean value indicating the empty status of the list |
| remove | | public void remove(ObjectSinkNode node)(Code) | | Removes a ObjectSinkNode from the list. This works by attach the previous reference to the child reference.
When the node to be removed is the first node it calls removeFirst(). When the node to be removed is the last node
it calls removeLast().
Parameters:
node - The ObjectSinkNode to be removed. |
| removeFirst | | public ObjectSinkNode removeFirst()(Code) | | Remove the first node from the list. The next node then becomes the first node. If this is the last
node then both first and last node references are set to null.
The first ObjectSinkNode. |
| removeLast | | public ObjectSinkNode removeLast()(Code) | | Remove the last node from the list. The previous node then becomes the last node. If this is the last
node then both first and last node references are set to null.
The first ObjectSinkNode. |
| size | | final public int size()(Code) | | return size of the list as an int |
