YList.ListCursorImpl

Constructor Summary

NodeList()
Creates an empty List.

NodeList(Iterator it)
Creates a list that is initialized with the elements provided by the Iterator it.

NodeList(Node v)
Creates a list that is initialized with a single element provided

NodeList(Node[] a)
Creates a list that is initialized with the elements provided by the given array of Nodes

NodeList(NodeCursor c)
Creates a list containing the nodes accessible via the given node cursor.

NodeList(NodeCursor nc, DataProvider predicate)

Constructor Detail

NodeList

public NodeList()

Creates an empty List.

NodeList

public NodeList(NodeCursor c)

Creates a list containing the nodes accessible via the given node cursor.

Parameters:

c - A node cursor providing nodes that are initially entered into this list.

NodeList

public NodeList(NodeCursor nc,
                DataProvider predicate)

Creates a list containing the nodes accessible via the given node cursor for which the given data provider returns true upon calling its getBool method.

Parameters:

nc - a node cursor providing nodes that are initially entered into this list.

predicate - a dataprovider that acts as a inclusion predicate for each node accessible from the node cursor
