All known Subclasses: com.sun.perseus.model.ElementNode, com.sun.perseus.model.Viewport,
| CompositeNode | | abstract public class CompositeNode extends ModelNode (Code) | | CompositeNode models ModelNodesElementNode ElementNodes .
A CompositeNode can have either ModelNode
children and text content children (see the
CompositeNode.appendTextChild appendTextChild method).

| Method Summary | |
| public void | add(ElementNode element)
| | public Node | appendChild(Node newChild)
| | protected void | clearLayouts()
Clears the text layouts, if any exist. | | public ModelNode | getFirstChildNode()
| | public ModelNode | getLastChildNode()
| | abstract public String | getLocalName()
unprefixed node name. | | abstract public String | getNamespaceURI()
| | abstract public Node | getParentNode()
Returns the parent Node of this Node.
the parent node or null if there is no parent (i.e. | | public Node | insertBefore(Node newChild, Node refChild)
| | protected boolean | isAllowedChild(ElementNode node)
Implementation helper. | | final boolean | isAncestor(ElementNode node)
Implementation helper.
Parameters:
node - the node which may be an ancestor of this CompositeNode. | | final boolean | isChild(Node node)
Implementation helper.
Parameters:
node - the node which may be a child of this composite node. | | protected static boolean | isIdBranch(ElementNode node)
Parameters:
node - the root of the branch to check for ids. | | protected boolean | isRemoveChildSupported()
true if this node supports removing children. | | void | nodeHookedInDocumentTree()
To be overriddent by derived classes, such as TimedElementNode,
if they need to do special operations when hooked into the
document tree. | | void | nodeUnhookedFromDocumentTree()
To be overriddent by derived classes, such as TimedElementNode,
if they need to do special operations when unhooked from the
document tree. | | final void | onHookedInDocumentTree()
When a CompositeNode is hooked into the document tree, by default,
it notifies its children and calls its own nodeHookedInDocumentTree
method. | | final void | onUnhookedFromDocumentTree()
When a CompositeNode is hooked into the document tree, by default,
it notifies its children and calls its own nodeUnhookedFromDocumentTree
method. | | public Node | removeChild(Node oldChild)
| | protected void | unhookChildrenQuiet()
Utility method. |
| add | | public void add(ElementNode element)(Code) | | Appends an element at the end of the list
Parameters:
element - the node to add to this CompositeNode
throws:
NullPointerException - if the input argument is null. |
| clearLayouts | | protected void clearLayouts()(Code) | | Clears the text layouts, if any exist. This is typically
called when the font selection has changed and nodes such
as Text should recompute their layouts.
This should recursively call clearLayouts on children
node or expanded content, if any.
|
| getFirstChildNode | | public ModelNode getFirstChildNode()(Code) | | this node's first child. |
| getLastChildNode | | public ModelNode getLastChildNode()(Code) | | this node's last child. |
| getLocalName | | abstract public String getLocalName()(Code) | | unprefixed node name. For an SVGElement, this returns the tagname without a prefix. In case of the Document node, string#document is returned.
throws:
SecurityException - if the application does not have the necessaryprivilege rights to access this (SVG) content. |
| getNamespaceURI | | abstract public String getNamespaceURI()(Code) | | the namespace URI of the Node.
throws:
SecurityException - if the application does not have the necessaryprivilege rights to access this (SVG) content. |
| getParentNode | | abstract public Node getParentNode()(Code) | | Returns the parent Node of this Node.
the parent node or null if there is no parent (i.e. if a node hasjust been created and not yet added to the tree, or if it has beenremoved from the tree, this is null).
throws:
SecurityException - if the application does not have the necessaryprivilege rights to access this (SVG) content. |
| isAllowedChild | | protected boolean isAllowedChild(ElementNode node)(Code) | | Implementation helper. By default, we only disallow SVG nodes under
all nodes except DocumentNode.
Parameters:
node - the candidate child node. true if the input node can be inserted under this CompositeNode |
| isAncestor | | final boolean isAncestor(ElementNode node)(Code) | | Implementation helper.
Parameters:
node - the node which may be an ancestor of this CompositeNode. true if the input node is this node or if it is one of its ancestors. |
| isChild | | final boolean isChild(Node node)(Code) | | Implementation helper.
Parameters:
node - the node which may be a child of this composite node. true if the input node is one of this composite's children. |
| isIdBranch | | protected static boolean isIdBranch(ElementNode node)(Code) | |
Parameters:
node - the root of the branch to check for ids. Should not be null. true if the input node, or any of its descendant, has an id. |
| isRemoveChildSupported | | protected boolean isRemoveChildSupported()(Code) | | true if this node supports removing children. By default, thisreturns true. |
| nodeHookedInDocumentTree | | void nodeHookedInDocumentTree()(Code) | | To be overriddent by derived classes, such as TimedElementNode,
if they need to do special operations when hooked into the
document tree.
|
| nodeUnhookedFromDocumentTree | | void nodeUnhookedFromDocumentTree()(Code) | | To be overriddent by derived classes, such as TimedElementNode,
if they need to do special operations when unhooked from the
document tree.
|
| onHookedInDocumentTree | | final void onHookedInDocumentTree()(Code) | | When a CompositeNode is hooked into the document tree, by default,
it notifies its children and calls its own nodeHookedInDocumentTree
method.
|
| onUnhookedFromDocumentTree | | final void onUnhookedFromDocumentTree()(Code) | | When a CompositeNode is hooked into the document tree, by default,
it notifies its children and calls its own nodeUnhookedFromDocumentTree
method.
|
| unhookChildrenQuiet | | protected void unhookChildrenQuiet()(Code) | | Utility method. Unhooks the children.
