ParentNode inherits from ChildNode and adds the capability of having child nodes. Not every node in the DOM can have children, so only nodes that can should inherit from this class and pay the price for it.

ParentNode, just like NodeImpl, also implements NodeList, so it can return itself in response to the getChildNodes() query. This eliminiates the need for a separate ChildNodeList object. Note that this is an IMPLEMENTATION DETAIL; applications should _never_ assume that this identity exists. On the other hand, subclasses may need to override this, in case of conflicting names. This is the case for the classes HTMLSelectElementImpl and HTMLFormElementImpl of the HTML DOM.

While we have a direct reference to the first child, the last child is stored as the previous sibling of the first child. First child nodes are marked as being so, and getNextSibling hides this fact.

Note

Not all parent nodes actually need to also be a child. At some point we used to have ParentNode inheriting from NodeImpl and another class called ChildAndParentNode that inherited from ChildNode. But due to the lack of multiple inheritance a lot of code had to be duplicated which led to a maintenance nightmare. At the same time only a few nodes (Document, DocumentFragment, Entity, and Attribute) cannot be a child so the gain in memory wasn't really worth it. The only type for which this would be the case is Attribute, but we deal with there in another special way, so this is not applicable.

This class doesn't directly support mutation events, however, it notifies the document when mutations are performed so that the document class do so.

Warning

Some of the code here is partially duplicated in AttrImpl, be careful to keep these two classes in sync!

Method Detail

checkNormalizationAfterInsertback to summary
pack-priv void checkNormalizationAfterInsert(ChildNode insertedChild)

Checks the normalized state of this node after inserting a child. If the inserted child causes this node to be unnormalized, then this node is flagged accordingly. The conditions for changing the normalized state are:

  • The inserted child is a text node and one of its adjacent siblings is also a text node.
  • The inserted child is is itself unnormalized.
Parameters
insertedChild:ChildNode

the child node that was inserted into this node

Exceptions
NullPointerException:
if the inserted child is null
checkNormalizationAfterRemoveback to summary
pack-priv void checkNormalizationAfterRemove(ChildNode previousSibling)

Checks the normalized of this node after removing a child. If the removed child causes this node to be unnormalized, then this node is flagged accordingly. The conditions for changing the normalized state are:

  • The removed child had two adjacent siblings that were text nodes.
Parameters
previousSibling:ChildNode

the previous sibling of the removed child, or null

cloneNodeback to summary
public Node cloneNode(boolean deep)

Overrides com.sun.org.apache.xerces.internal.dom.ChildNode.cloneNode.

Implements org.w3c.dom.Node.cloneNode.

Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.

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.

Parameters
deep:boolean

Doc from org.w3c.dom.Node.cloneNode.

If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:Node

Doc from org.w3c.dom.Node.cloneNode.

The duplicate node.

getChildNodesback to summary
public NodeList getChildNodes()

Overrides com.sun.org.apache.xerces.internal.dom.NodeImpl.getChildNodes.

Implements org.w3c.dom.Node.getChildNodes.

Obtain a NodeList enumerating all children of this node. If there are none, an (initially) empty NodeList is returned.

NodeLists are "live"; as children are added/removed the NodeList will immediately reflect those changes. Also, the NodeList refers to the actual nodes, so changes to those nodes made via the DOM tree will be reflected in the NodeList and vice versa.

In this implementation, Nodes implement the NodeList interface and provide their own getChildNodes() support. Other DOMs may solve this differently.

getChildNodesUnoptimizedback to summary
protected final NodeList getChildNodesUnoptimized()

Create a NodeList to access children that is use by subclass elements that have methods named getLength() or item(int). ChildAndParentNode optimizes getChildNodes() by implementing NodeList itself. However if a subclass Element implements methods with the same name as the NodeList methods, they will override the actually methods in this class.

To use this method, the subclass should implement getChildNodes() and have it call this method. The resulting NodeList instance maybe shared and cached in a transient field, but the cached value must be cleared if the node is cloned.

getFirstChildback to summary
public Node getFirstChild()

Overrides com.sun.org.apache.xerces.internal.dom.NodeImpl.getFirstChild.

Implements org.w3c.dom.Node.getFirstChild.

Implements org.w3c.dom.NodeList.getLength.

NodeList method: Count the immediate children of this node

Returns:int

getOwnerDocumentback to summary

Overrides com.sun.org.apache.xerces.internal.dom.NodeImpl.getOwnerDocument.

Implements org.w3c.dom.Node.getOwnerDocument.

getTextContentback to summary
public String getTextContent() throws DOMException

Overrides com.sun.org.apache.xerces.internal.dom.NodeImpl.getTextContent.

Implements org.w3c.dom.Node.getTextContent.

Doc from com.sun.org.apache.xerces.internal.dom.NodeImpl.getTextContent.

This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single Text node containing the string this attribute is set to. 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:
