Method Details

isNodeInclude

public int isNodeInclude(Node currentNode)

Description copied from interface: NodeFilter

Tells if a node must be output in c14n.

Specified by:

isNodeInclude in interface NodeFilter

Parameters:

currentNode -

Returns:

1 if the node should be output. 0 if node must not be output, -1 if the node and all it's child must not be output.

• NodeFilter.isNodeInclude(org.w3c.dom.Node)

isNodeIncludeDO

public int isNodeIncludeDO(Node n,
 int level)

Description copied from interface: NodeFilter

Tells if a node must be output in a c14n. The caller must assured that this method is always call in document order. The implementations can use this restriction to optimize the transformation.

Specified by:

isNodeIncludeDO in interface NodeFilter

Parameters:

n -

level - the relative level in the tree

Returns:

1 if the node should be output. 0 if node must not be output, -1 if the node and all it's child must not be output.

rooted

static boolean rooted(Node currentNode,
 Set<Node> nodeList)

Method rooted

Parameters:

currentNode -

nodeList -

Returns:

if rooted bye the rootnodes

inList

static boolean inList(Node currentNode,
 Set<Node> nodeList)

Method rooted

Parameters:

currentNode -

nodeList -

Returns:

if rooted bye the rootnodes

convertNodeListToSet

private static Set<Node> convertNodeListToSet(List<NodeList> l)
