public class MutableNodeListImpl

extends NodeVector

implements MutableNodeList

Implementation of MutableNodeList.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Constructor Detail

MutableNodeListImpl

public MutableNodeListImpl()

Create an empty nodelist.

MutableNodeListImpl

public MutableNodeListImpl(int blocksize)

Create an empty nodelist.

MutableNodeListImpl

public MutableNodeListImpl(org.w3c.dom.NodeList nodelist)

Create a MutableNodeListImpl, and copy the members of the given nodelist into it.

MutableNodeListImpl

public MutableNodeListImpl(org.w3c.dom.Node node)

Create a MutableNodeListImpl, and copy the members of the given nodelist into it.

Method Detail

item

public org.w3c.dom.Node item(int index)

Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null.

Parameters:

index - Index into the collection.

Returns:

The node at the indexth position in the NodeList, or null if that is not a valid index.

getLength

public int getLength()

The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive.

checkDups

public boolean checkDups(org.w3c.dom.Node node)

Check for duplicates, for diagnostics.

checkDups

public boolean checkDups()

addNode

public void addNode(org.w3c.dom.Node n)

Add a node.

Specified by:

addNode in interface MutableNodeList

insertNode

public void insertNode(org.w3c.dom.Node n,
                       int pos)

Insert a node at a given position.

Specified by:

insertNode in interface MutableNodeList

removeNode

public void removeNode(org.w3c.dom.Node n)

Remove a node.

Specified by:

removeNode in interface MutableNodeList

setItemNull

public void setItemNull(int pos)

Set a item to null, so the list doesn't have to keep being compressed.

Specified by:

setItemNull in interface MutableNodeList

addNodes

public void addNodes(org.w3c.dom.NodeList nodelist)

Copy NodeList members into this nodelist, adding in document order. If a node is null, don't add it.

Specified by:

addNodes in interface MutableNodeList

addNodesInDocOrder

public void addNodesInDocOrder(org.w3c.dom.NodeList nodelist,
                               XPathSupport support)

Copy NodeList members into this nodelist, adding in document order. If a node is null, don't add it.

Specified by:

addNodesInDocOrder in interface MutableNodeList

addNodeInDocOrder

public int addNodeInDocOrder(org.w3c.dom.Node node,
                             boolean test,
                             XPathSupport support)

Add the node into a vector of nodes where it should occur in document order.

Specified by:

addNodeInDocOrder in interface MutableNodeList

Parameters:

v - Vector of nodes, presumably containing Nodes

obj - Node object.

test - true if we should test for doc order

Returns:

insertIndex.

addNodeInDocOrder

public int addNodeInDocOrder(org.w3c.dom.Node node,
                             XPathSupport support)

Add the node into a vector of nodes where it should occur in document order.

Specified by:

addNodeInDocOrder in interface MutableNodeList

Parameters:

v - Vector of nodes, presumably containing Nodes

obj - Node object.

isNodeAfter

public static boolean isNodeAfter(org.w3c.dom.Node node1,
                                  org.w3c.dom.Node node2,
                                  XPathSupport support)

Figure out if node2 should be placed after node1 when placing nodes in a list that is to be sorted in document order. Assumes that node1 and node2 are not equal. NOTE: Make sure this does the right thing with attribute nodes!!!

Returns:

true if node2 should be placed after node1, and false if node2 should be placed before node1.
