DocumentImpl

public class CoreDocumentImpl
extends ParentNode
implements org.w3c.dom.Document

The Document interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data.

Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a Document, the Document interface also contains the factory methods needed to create these objects. The Node objects created have a ownerDocument attribute which associates them with the Document within whose context they were created.

The CoreDocumentImpl class only implements the DOM Core. Additional modules are supported by the more complete DocumentImpl subclass.

Note: When any node in the document is serialized, the entire document is serialized along with it.

Since:
PR-DOM-Level-1-19980818.

changes

protected int changes
Number of alterations made to this document since its creation. Serves as a "dirty bit" so that live objects such as NodeList can recognize when an alteration has been made and discard its cached state information.

Any method that alters the tree structure MUST cause or be accompanied by a call to changed(), to inform it that any outstanding NodeLists may have to be updated.

(Required because NodeList is simultaneously "live" and integer- indexed -- a bad decision in the DOM's design.)

Note that changes which do not affect the tree's structure -- changing the node's name, for example -- do _not_ have to call changed().

Alternative implementation would be to use a cryptographic Digest value rather than a count. This would have the advantage that "harmless" changes (those producing equal() trees) would not force NodeList to resynchronize. Disadvantage is that it's slightly more prone to "false negatives", though that's the difference between "wildly unlikely" and "absurdly unlikely". IF we start maintaining digests, we should consider taking advantage of them. Note: This used to be done a node basis, so that we knew what subtree changed. But since only DeepNodeList really use this today, the gain appears to be really small compared to the cost of having an int on every (parent) node plus having to walk up the tree all the way to the root to mark the branch as changed everytime a node is changed. So we now have a single counter global to the document. It means that some objects may flush their cache more often than necessary, but this makes nodes smaller and only the document needs to be marked as changed.

Method Detail

getOwnerDocument

public final org.w3c.dom.Document getOwnerDocument()
Description copied from class: ParentNode
Find the Document that this Node belongs to (the document in whose context the Node was created). The Node may or may not currently be part of that Document's actual contents.

Specified by:
getOwnerDocument in interface org.w3c.dom.Node
Overrides:
getOwnerDocument in class ParentNode

getNodeType

public short getNodeType()
Returns the node type.

Specified by:
getNodeType in interface org.w3c.dom.Node
Specified by:
getNodeType in class NodeImpl

getNodeName

public java.lang.String getNodeName()
Returns the node name.

Specified by:
getNodeName in interface org.w3c.dom.Node
Specified by:
getNodeName in class NodeImpl

cloneNode

public org.w3c.dom.Node cloneNode(boolean deep)
Deep-clone a document, including fixing ownerDoc for the cloned children. Note that this requires bypassing the WRONG_DOCUMENT_ERR protection. I've chosen to implement it by calling importNode which is DOM Level 2.

Specified by:
cloneNode in interface org.w3c.dom.Node
Overrides:
cloneNode in class ParentNode
Parameters:
deep - boolean, iff true replicate children
Returns:
org.w3c.dom.Node
See Also:

Example: Cloning a Text node will copy both the node and the text it contains.

Example: Cloning something that has children -- Element or Attr, for example -- will _not_ clone those children unless a "deep clone" has been requested. A shallow clone of an Attr node will yield an empty Attr of the same name.

NOTE: Clones will always be read/write, even if the node being cloned is read-only, to permit applications using only the DOM API to obtain editable copies of locked portions of the tree.


cloneNode

internal method to share code with subclass


insertBefore

                              throws org.w3c.dom.DOMException
Since a Document may contain at most one top-level Element child, and at most one DocumentType declaraction, we need to subclass our add-children methods to implement this constraint. Since appendChild() is implemented as insertBefore(,null), altering the latter fixes both.

While I'm doing so, I've taken advantage of the opportunity to cache documentElement and docType so we don't have to search for them. REVISIT: According to the spec it is not allowed to alter neither the document element nor the document type in any way

Specified by:
insertBefore in interface org.w3c.dom.Node
Overrides:
insertBefore in class ParentNode
Parameters:
newChild - The Node to be moved to our subtree. As a convenience feature, inserting a DocumentNode will instead insert all its children.
refChild - Current child which newChild should be placed immediately before. If refChild is null, the insertion occurs after all existing Nodes, like appendChild().
Returns:
newChild, in its new state (relocated, or emptied in the case of DocumentNode.)
Throws:
org.w3c.dom.DOMException

On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
The string returned is made of the text content of this node depending on its type, as defined below:
Node type Content
ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue

abort

public void abort()
DOM Level 3 WD - Experimental. If the document is currently being loaded as a result of the method load being invoked the loading and parsing is immediately aborted. The possibly partial result of parsing the document is discarded and the document is cleared.


load

public boolean load(java.lang.String uri)
DOM Level 3 WD - Experimental. Replaces the content of the document with the result of parsing the given URI. Invoking this method will either block the caller or return to the caller immediately depending on the value of the async attribute. Once the document is fully loaded a "load" event (as defined in [DOM Level 3 Events] , except that the Event.targetNode will be the document, not an element) will be dispatched on the document. If an error occurs, an implementation dependent "error" event will be dispatched on the document. If this method is called on a document that is currently loading, the current load is interrupted and the new URI load is initiated.
When invoking this method the parameters used in the DOMParser interface are assumed to have their default values with the exception that the parameters "entities" , "normalize-characters", "check-character-normalization" are set to "false".
The result of a call to this method is the same the result of a call to DOMParser.parseWithContext with an input stream referencing the URI that was passed to this call, the document as the context node, and the action ACTION_REPLACE_CHILDREN.

Parameters:
uri - The URI reference for the XML file to be loaded. If this is a relative URI, the base URI used by the implementation is implementation dependent.
Returns:
If async is set to true load returns true if the document load was successfully initiated. If an error occurred when initiating the document load, load returns false.If async is set to false load returns true if the document was successfully loaded and parsed. If an error occurred when either loading or parsing the URI, load returns false.

loadXML

public boolean loadXML(java.lang.String source)
DOM Level 3 WD - Experimental. Replace the content of the document with the result of parsing the input string, this method is always synchronous.

Parameters:
source - A string containing an XML document.
Returns:
true if parsing the input string succeeded without errors, otherwise false.

DOM Level 3 WD - Experimental. Save the document or the given node and all its descendants to a string (i.e. serialize the document or node).
The parameters used in the LSSerializer interface are assumed to have their default values when invoking this method.
The result of a call to this method is the same the result of a call to LSSerializer.writeToString with the document as the node to write.

Parameters:
node - Specifies what to serialize, if this parameter is null the whole document is serialized, if it's non-null the given node is serialized.
Returns:
The serialized document or null in case an error occurred.
Throws:
org.w3c.dom.DOMException - WRONG_DOCUMENT_ERR: Raised if the node passed in as the node parameter is from an other document.

Parameters:
namespaceURI - The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName.
localName - The local name of the elements to match on. The special value "*" matches all local names.
Returns:
NodeList A new NodeList object containing all the matched Elements.

Uses the kidOK lookup table to check whether the proposed tree structure is legal.


changed

protected void changed()
Denotes that this node has changed.

Overrides:
changed in class NodeImpl

setUserData

public java.lang.Object setUserData(org.w3c.dom.Node n,
                                    java.lang.String key,
                                    java.lang.Object data,
                                    org.w3c.dom.UserDataHandler handler)
Associate an object to a key on this node. The object can later be retrieved from this node by calling getUserData with the same key.

Parameters:
n - The node to associate the object to.
key - The key to associate the object to.
data - The object to associate to the given key, or null to remove any existing association to that key.
handler - The handler to associate to that key, or null.
Returns:
Returns the DOMObject previously associated to the given key on this node, or null if there was none.
Since:
DOM Level 3 REVISIT: we could use a free list of UserDataRecord here

getUserData

public java.lang.Object getUserData(org.w3c.dom.Node n,
                                    java.lang.String key)
Retrieves the object associated to a key on a this node. The object must first have been set to this node by calling setUserData with the same key.

Parameters:
n - The node the object is associated to.
key - The key the object is associated to.
Returns:
Returns the DOMObject associated to the given key on this node, or null if there was none.
Since:
DOM Level 3

getUserDataRecord

protected java.util.Hashtable getUserDataRecord(org.w3c.dom.Node n)

callUserDataHandlers

protected void callUserDataHandlers(org.w3c.dom.Node n,
                                    org.w3c.dom.Node c,
                                    short operation)
Call user data handlers when a node is deleted (finalized)

Parameters:
n - The node this operation applies to.
c - The copy node or null.
operation - The operation - import, clone, or delete.

checkNamespaceWF

protected final void checkNamespaceWF(java.lang.String qname,
                                      int colon1,
                                      int colon2)
Call user data handlers to let them know the nodes they are related to are being deleted. The alternative would be to do that on Node but because the nodes are used as the keys we have a reference to them that prevents them from being gc'ed until the document is. At the same time, doing it here has the advantage of avoiding a finalize() method on Node, which would affect all nodes and not just the ones that have a user data.


checkDOMNSErr

protected final void checkDOMNSErr(java.lang.String prefix,
                                   java.lang.String namespace)

checkQName

protected final void checkQName(java.lang.String prefix,
                                java.lang.String local)
Checks if the given qualified name is legal with respect to the version of XML to which this document must conform.

Parameters:
prefix - prefix of qualified name
local - local part of qualified name

setUserData

protected void setUserData(NodeImpl n,
                           java.lang.Object data)
NON-DOM: kept for backward compatibility Store user data related to a given node This is a place where we could use weak references! Indeed, the node here won't be GC'ed as long as some user data is attached to it, since the userData table will have a reference to the node.


getUserData

protected java.lang.Object getUserData(NodeImpl n)
NON-DOM: kept for backward compatibility Retreive user data related to a given node
