Interface DoubleLinkedNode<V,NODE extends DoubleLinkedNode<V,NODE>>

Type Parameters:

V - is the generic type of the value of this node.

NODE - is the generic type of the node itself.

All Superinterfaces:

LinkedNode<V,NODE>

All Known Implementing Classes:

BasicDoubleLinkedNode

public interface DoubleLinkedNode<V,NODE extends DoubleLinkedNode<V,NODE>>
extends LinkedNode<V,NODE>

This is the interface for a node of a double linked list.
ATTENTION:
According to the generic-type-system of Java this interface can not be used as a proper API until the generic <NODE> is finally bound. Please use BasicDoubleLinkedNode instead.

Method Detail

getPrevious

NODE getPrevious()

This method gets the previous node of the double linked list.

Returns:

the previous node or null if this is the first node (head).

isLinked

boolean isLinked()

This method determines if this node is linked. A node is linked if it has a next node. A node is also linked if it has a previous node.

Specified by:

isLinked in interface LinkedNode<V,NODE extends DoubleLinkedNode<V,NODE>>

Returns:

true if linked, false otherwise.
