All known Subclasses: com.sun.perseus.model.CompositeGraphicsNodeProxy,
| ElementNodeProxy | | public class ElementNodeProxy extends ModelNode (Code) | | A ElementNodeProxy delegates its rendering to a
proxied ElementNode object. This class is used to
model expanded content. SVG markup defines content that needs to
be expanded before it is rendered. For example, the <use>
element is expanded with ElementNodeProxy children
to represent the expansion expressed by the element.

| expanded | | protected boolean expanded(Code) | | Controls whether content is expanded or not
|
| firstExpandedChild | | protected ModelNode firstExpandedChild(Code) | | The first expanded child, if content has been expanded.
|
| lastExpandedChild | | protected ModelNode lastExpandedChild(Code) | | The last expanded child, if content has been expanded
|
| ElementNodeProxy | | protected ElementNodeProxy(ElementNode proxiedNode)(Code) | |
Parameters:
proxiedNode - ElementNode to proxy |
| appendTransform | | protected Transform appendTransform(Transform tx, Transform workTx)(Code) | | Appends the proxied node's transform, if there is a proxied node.
Parameters:
tx - the Transform to apply additional node transforms to. This may be null.
Parameters:
workTx - a Transform which can be re-used if a new Transform needs to be created and workTxis not the same instance as tx. a transform with this node's transform added. |
| 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.
|
| computeProxiesChain | | protected ElementNodeProxy computeProxiesChain(ElementNode proxiedChild)(Code) | | Implementation helper: computes the set of chained proxies
for the input node and return the head of the chain.
Parameters:
proxiedChild - the ElementNode for which the chain of proxies should be computed. the head of the proxies chaing. NOTE that the prevSiblingis set on the head to point to the last element of the chain,creating a circular list for the 'prevSibling' reference. Thiscircular reference should be broken by the code using this method. |
| expand | | protected void expand()(Code) | | Expand the content. This is done lazilly
|
| getFirstChildNode | | public ModelNode getFirstChildNode()(Code) | | a reference to the node's first child, or null if thereare no children. |
| getFirstComputedExpandedChild | | public ModelNode getFirstComputedExpandedChild()(Code) | | Some node types (such as ElementNodeProxy) have
expanded children that they compute in some specific
way depending on the implementation.
a reference to the node's first expanded child, or null if thereare no expanded children. |
| getFirstExpandedChild | | public ModelNode getFirstExpandedChild()(Code) | | Some node types (such as ElementNodeProxy) have
expanded children that they compute in some specific
way depending on the implementation.
a reference to the node's first expanded child, or null if thereare no expanded children. This forces the computation of expandedcontent if needed. |
| getLastChildNode | | public ModelNode getLastChildNode()(Code) | | a reference to the node's last child, or null if thereare no children. |
| getLastExpandedChild | | public ModelNode getLastExpandedChild()(Code) | | Some node types (such as ElementNodeProxy) have
expanded children that they compute in some specific
way depending on the implementation.
a reference to the node's last expanded child, or null if thereare no expanded children. This forces the computation of expandedcontent if needed. |
| hasDescendants | | public boolean hasDescendants()(Code) | | true if the ElementNodeProxy has children or if it hasexpanded content. |
| modifiedProxied | | public void modifiedProxied()(Code) | | Proxied nodes should call this method when they have been modified.
|
| modifyingProxied | | public void modifyingProxied()(Code) | | Proxied nodes should call this method when they are being modified.
|
| nodeHitAt | | public ModelNode nodeHitAt(float[] pt)(Code) | | Returns the ModelNode, if any, hit by the
point at coordinate x/y.
Parameters:
pt - the x/y coordinate. Should never be null and beof size two. If not, the behavior is unspecified.The coordinates are in viewport space. the ModelNode hit at the given point or nullif none was hit. |
| 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.
|
| proxiedChildAdded | | public void proxiedChildAdded(ElementNode child)(Code) | | Proxied nodes should call this method they got a new added child.
This is an optimization of the more generic insertion
case. Appending a child is a recursive process which avoids
recomputing all the proxies recursively (a proxy referencing a proxy
referencing a proxy .... referencing a composite on which nodes are
appended). It might be advantageous to consider doing a generic
optimized insertion into the children list.
Parameters:
child - the ElementNode which was just added underthe proxied node.
See Also: ElementNodeProxy.proxiedExpandedChildAdded |
| setProxied | | protected void setProxied(ElementNode newProxied)(Code) | | Modifies the node proxied by this proxy.
Parameters:
newProxied - this node's new proxied node |
| unhookChildrenQuiet | | protected void unhookChildrenQuiet()(Code) | | Does nothing, as there are no children.
|
| unhookExpandedQuiet | | protected void unhookExpandedQuiet()(Code) | | Utility method. Unhooks the expanded content.
