| DTMChildIterNodeList | | public class DTMChildIterNodeList extends DTMNodeListBase (Code) | | DTMNodeList gives us an implementation of the DOM's
NodeList interface wrapped around a DTM Iterator. The author
considers this something of an abominations, since NodeList was not
intended to be a general purpose "list of nodes" API and is
generally considered by the DOM WG to have be a mistake... but I'm
told that some of the XPath/XSLT folks say they must have this
solution.
Please note that this is not necessarily equivlaent to a DOM
NodeList operating over the same document. In particular:
- If there are several Text nodes in logical succession (ie,
across CDATASection and EntityReference boundaries), we will return
only the first; the caller is responsible for stepping through
them.
(%REVIEW% Provide a convenience routine here to assist, pending
proposed DOM Level 3 getAdjacentText() operation?)
- Since the whole XPath/XSLT architecture assumes that the source
document is not altered while we're working with it, we do not
promise to implement the DOM NodeList's "live view" response to
document mutation.
State: In progress!!

| Constructor Summary | |
| public | DTMChildIterNodeList(DTM parentDTM, int parentHandle)
Public constructor: Create a NodeList to support
DTMNodeProxy.getChildren().
Unfortunately AxisIterators and DTMIterators don't share an API,
so I can't use the existing Axis.CHILD iterator. |
| Method Summary | |
| public int | getLength()
The number of nodes in the list. | | public Node | item(int index)
Returns the indexth item in the collection. |
| DTMChildIterNodeList | | public DTMChildIterNodeList(DTM parentDTM, int parentHandle)(Code) | | Public constructor: Create a NodeList to support
DTMNodeProxy.getChildren().
Unfortunately AxisIterators and DTMIterators don't share an API,
so I can't use the existing Axis.CHILD iterator. Rather than
create Yet Another Class, let's set up a special case of this
one.
Parameters:
parentDTM - The DTM containing this node
Parameters:
parentHandle - DTM node-handle integer |
| getLength | | public int getLength()(Code) | | The number of nodes in the list. The range of valid child node indices
is 0 to length-1 inclusive.
|
| item | | public Node item(int index)(Code) | | 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. The node at the indexth position in the NodeList, or null if that is not a valid index. |
