org.xml.sax.ContentHandler |
getcontentHandler()
Get the ContentHandler used for the tree walk.
|
void |
setcontentHandler(org.xml.sax.ContentHandler ch)
Set the ContentHandler used for the tree walk.

void |
setDTM(DTM dtm)
Set the DTM to be traversed.
|
void |
traverse(int pos)
Perform a non-recursive pre-order/post-order traversal,
operating as a Visitor. startNode (preorder) and endNode
(postorder) are invoked for each node as we traverse over them,
with the result that the node is written out to m_contentHandler.

void |
traverse(int pos,
int top)
Perform a non-recursive pre-order/post-order traversal,
operating as a Visitor. startNode (preorder) and endNode
(postorder) are invoked for each node as we traverse over them,
with the result that the node is written out to m_contentHandler.
