m_attribute

protected SuballocatedIntVector m_attribute

For each element node, there can be zero or more attributes. If Attributes are assigned, the first attribute for that element will be use here. Subsequent elements will use the m_nextsib, m_prevsib array. The sibling arrays are not meeant to hold indexes to attribute information but as long as there is not direct connection back into the main DTM tree we should be OK.

m_DocumentIdx

protected int m_DocumentIdx

The Document Index will most likely be 0, but we will reference it by variable in case that paradigm falls through.

Method Detail

allocateNodeObject

private int allocateNodeObject(Object o)

                                 int pnode)

Link an attribute to a node, if the node already has one or more attributes assigned, then just link this one to the attribute list. The first attribute is attached to the Parent Node (pnode) through the m_attribute array, subsequent attributes are linked through the m_prevsib, m_nextsib arrays.

Returns:

cloneAttributeFromNode

protected void cloneAttributeFromNode(int toNode,
                                      int fromNode)

Allow two nodes to share the same set of attributes. There may be some problems because the parent of any attribute will be the original node they were assigned to. Need to see how the attribute walker works, then we should be able to fake it out.

dispatchNodeData

protected static void dispatchNodeData(org.w3c.dom.Node node,
                                       org.xml.sax.ContentHandler ch,
                                       int depth)
                                throws org.xml.sax.SAXException

Retrieve the text content of a DOM subtree, appending it into a user-supplied FastStringBuffer object. Note that attributes are not considered part of the content of an element.

There are open questions regarding whitespace stripping. Currently we make no special effort in that regard, since the standard DOM doesn't yet provide DTD-based information to distinguish whitespace-in-element-context from genuine #PCDATA. Note that we should probably also consider xml:space if/when we address this. DOM Level 3 may solve the problem for us.

%REVIEW% Note that as a DOM-level operation, it can be argued that this routine _shouldn't_ perform any processing beyond what the DOM already does, and that whitespace stripping and so on belong at the DTM level. If you want a stripped DOM view, wrap DTM2DOM around DOM2DTM.

Parameters:

node - Node whose subtree is to be walked, gathering the contents of all Text or CDATASection nodes.

ch -

depth -

Returns:

Throws:

org.xml.sax.SAXException

value - an Object value

Returns:

getSourceLocatorFor

public javax.xml.transform.SourceLocator getSourceLocatorFor(int node)

No source information is available for DOM2DTM, so return null here.

Parameters:

Specified by:

Parameters:

parm1 -

Returns:

getUnparsedEntityURI

public String getUnparsedEntityURI(String parm1)

Description copied from class: DTMDefaultBase

The getUnparsedEntityURI function returns the URI of the unparsed entity with the specified name in the same document as the context node (see [3.3 Unparsed Entities]). It returns the empty string if there is no such entity.

XML processors may choose to use the System Identifier (if one is provided) to resolve the entity, rather than the URI in the Public Identifier. The details are dependent on the processor, and we would have to support some form of plug-in resolver to handle this properly. Currently, we simply return the System Identifier if present, and hope that it a usable URI or that our caller can map it to one. TODO: Resolve Public Identifiers... or consider changing function name.

If we find a relative URI reference, XML expects it to be resolved in terms of the base URI of the document. The DOM doesn't do that for us, and it isn't entirely clear whether that should be done here; currently that's pushed up to a higher level of our application. (Note that DOM Level 1 didn't store the document's base URI.) TODO: Consider resolving Relative URIs.

(The DOM's statement that "An XML processor may choose to completely expand entities before the structure model is passed to the DOM" refers only to parsed entities, not unparsed, and hence doesn't affect this function.)

Description copied from class: DTMDefaultBase

%REVIEW% This is obviously useful at the DOM layer, where it would permit testing this without having to create a proxy node. It's less useful in the DTM API, where (dtm.getFirstChild(nodeHandle)!=DTM.NULL) is just as fast and almost as self-evident. But it's a convenience, and eases porting of DOM code to DTM.

Parameters:

parm1 -

Returns:

getNodeType

public short getNodeType(int parm1)

Description copied from class: DTMDefaultBase

Given a node handle, return its DOM-style node type.

%REVIEW% Generally, returning short is false economy. Return int? %REVIEW% Make assumption that node has already arrived. Is OK?

Parameters:

parm1 -

Returns:

isCharacterElementContentWhitespace

public boolean isCharacterElementContentWhitespace(int parm1)

Description copied from class: DTMDefaultBase

2. [element content whitespace] A boolean indicating whether the character is white space appearing within element content (see [XML], 2.10 "White Space Handling"). Note that validating XML processors are required by XML 1.0 to provide this information. If there is no declaration for the containing element, this property has no value for white space characters. If no declaration has been read, but the [all declarations processed] property of the document information item is false (so there may be an unread declaration), then the value of this property is unknown for white space characters. It is always false for characters that are not white space.

Parameters:

parm1 -

Returns:

Description copied from class: DTMDefaultBase

Build table of namespace declaration locations during DTM construction. Table is a Vector of SuballocatedIntVectors containing the namespace node HANDLES declared at that ID, plus an SuballocatedIntVector of the element node INDEXES at which these declarations appeared. NOTE: Since this occurs during model build, nodes will be encountered in doucment order and thus the table will be ordered by element, permitting binary-search as a possible retrieval optimization. %REVIEW% Directly managed arrays rather than vectors? %REVIEW% Handles or IDs? Given usage, I think handles.
