Constructor Detail

RecyclingLinkedList

public RecyclingLinkedList()

Construct an empty List.

RecyclingLinkedList

public RecyclingLinkedList(int cMaxRecycle)

Construct an empty List.

Parameters:

cMaxRecycle - the maximum number of Nodes to recycle at any given time

RecyclingLinkedList

public RecyclingLinkedList(java.util.Collection collection)

Construct a List containing the elements of the specified Collection.

Parameters:

collection - the Collection to fill this List from

RecyclingLinkedList

public RecyclingLinkedList(java.util.Collection collection,
                           int cMaxRecycle)

Construct a List containing the elements of the specified Collection.

Parameters:

collection - the Collection to fill this List from

cMaxRecycle - the maximum number of Nodes to recycle at any given time

Method Detail

initRecycling

protected void initRecycling(int cMaxRecycle)

Initializing the recycling data structures.

Parameters:

cMaxRecycle - the maximum number of Nodes to recycle at any given time

instantiateNode

protected SafeLinkedList.Node instantiateNode(java.lang.Object o)

Instantiate a Node. (Factory pattern.) This method is over-ridden by inheriting implementations if the inheriting implementation extends the inner Node class.

Overrides:

instantiateNode in class SafeLinkedList

Parameters:

o - the value for the Node

recycleNode

protected void recycleNode(RecyclingLinkedList.Node node)

Recycle the passed Node.

Parameters:

node - the Node object to recycle

clone

public java.lang.Object clone()

Create a deep clone of the list.

Overrides:

clone in class SafeLinkedList

Returns:

a clone of this list
