Detailed Description

The node JavaScript global object.

Nodes are synonymous with Filter, IO, Move and Group in the Node View. With node methods, retrieve values from nodes, effects and composite. Add, link or set their attributes. Nodes can have identical names, so, their full path is needed to identify a them. The full path always starts with the root group name which is Top. Then, the other parent group names follow it separated by a "/". e.g. "Top/MyFirstGroup/MySecondGroup/MyNodeName". The nomenclature is a bit confusing, but node name methods use the path as the node name most of the time. The parentNode method from this class adds the Composite node in the parent group of the selected nodes. The link method, in a loop, connects all selected nodes to the new Composite node. The setCoord() method positions a new node in the Node View. The syntax for a node paths is: "Top/Group_Name/Node_Name".

function compose() 
{
 var n = selection.numberOfNodesSelected();
 var i, posx, posy; 
 if (n > 0) 
 { 
   var comp = node.add( node.parentNode(selection.selectedNode(0)), "comp", "COMPOSITE", 0, 0, 0); 
   posx = 0; 
   posy = -10000; 
   for (i = 0; i < n; ++i) 
   { 
     var selNode = selection.selectedNode(i); 
     node.link(selNode, 0, comp, i); 
     posx += node.coordX(selNode); 
     if (node.coordY(selNode) > posy) 
       posy = node.coordY(selNode); 
   } 
   posx /= n; 
   posy += 50; 
   node.setCoord(comp, posx, posy);
 }
}

  var listOfDestinationNodes = [];

  for(var i = 0; i<numOutput; i++)
    listOfDestinationNodes.push(node.dstNode(exampleNode, i, 0));

  return listOfDestinationNodes;
}
// For another example use of dstNode, see link().

The example below shows the relationship between dstNodeInfo and srcNode.

var exNode = selection.selectedNode(0);
var destination = node.dstNodeInfo(exNode, 0, 0);

//You can use the 2 properties of the source object to use srcNode()
 var source = node.srcNode(destination.node, destination.port);
MessageLog.trace(node.equals(source, exNode); //This will print true

Parameters

sourceNode	: The path of the source node.
iPort	: The output port number on which you want to find the connected node. This value is between 0 and the results of the numberOfOutputPorts() method, minus one.

This method returns an object that contains two properties: node - The path of connected node. port - The port number on which this node is connected to.

equals

bool node::equals ( String  node1, String  node2  )

slot

Returns true or false to indicate if a node path is equal to another. Used to compare node paths.

The example below deconstructs and then rebuilds a node path using subNodeByName, then compares the original to the rebuilt path. This example will print true. exNode is the full name of a node, such as "Top/MyGroup/MyNode".

function nodePathRebuild (exNode)
{
  var name = node.getName(exNode);
  var parent = node.parentNode(exNode);

  //With both the parent path and the node name, you can rebuild the original node with subNodeByName
  var rebuiltNode = node.subNodeByName(parent, exNode);
  //This rebuilt node will be equal to the original node
  MessageLog.trace(node.equals(exNode, rebuiltNode)); //This will print true

  MessageLog.trace(node.equals(exNode, node.noNode()); //Since exNode is a valid node, this will print false
}

Parameters

node1	: The path of the first node.
node2	: The path of the second node.

Returns

Returns true to indicate if the path of the first node is equal to the path of the second node.

explodeElementSymbolsInGroups

void node::explodeElementSymbolsInGroups ( String  element, bool  disableElement, bool  clearExposure, String &  prefix = String()  )

slot

Create a group for each exposure of the element where there is a symbol and will put the content of the symbol in that group.

If disable element is TRUE, will disable the element afterwards. If clearExposure is TRUE, will clear the exposures where there were symbols afterwards. Will use prefix as the prefix for the generated group names.

A symbol combines animation, artwork or layers into a single object that you can control in one layer.

The example below executes explodeElementSymbolsInGroup for the currently selected drawing node, and positions the newly created node groups to the left of the original node.

function explodeSymbol ()
{
  var symbolNode = selection.selectedNode(0);

  //Creates a symbol out of the currently selected drawing
  Action.perform("onActionCreateSymbolFromSelection()", "timelineView");

  var prefix = node.getName(symbolNode) + "_";
  var parent = node.parentNode(symbolNode);
  var path = parent + "/" + prefix;
  var i = 1;
  var x = node.coordX(symbolNode);
  var y = node.coordY(symbolNode);
  var flag = false;

  node.explodeElementSymbolsInGroup(symbolNode, true, false, prefix);

  while (i <= frame.numberOf() && flag == false)
  {
    if (node.type(path+i) != "")
    {
      node.setCoord((path+i), x, y);
    }
    else
    {
      flag = true;
    }
    y = y+20;
    i++;
  }
}

Parameters

element	: Element node path.
disableElement	: True to disable the exploded element.
clearExposure	: True to clear the exposure.
prefix	: Add a prefix to the symbols.

explodeGroup

bool node::explodeGroup ( String  groupName )

slot

Explode a group into its parent group. This method is identical to the "Explode Selected Group" from the Node View.

The following example creates a group then explodes the group if it was successful.

function groupExample ()
{
  var selected = selection.selectedNodes();
  var nodesToGroup = selected.join();
  var group = node.createGroup(nodesToGroup, "group");

  if (node.isGroup( group ))
    MessageLog.trace(node.explodeGroup(group));
}

Parameters

groupName

: The name of the node.

Returns

Returns true if successful.

flatSrcNode

String node::flatSrcNode ( String  node, int  iPort  )

slot

If the Source node is a Group, this method returns the path of the node inside the Group node that is the source. If the source is not inside a group, the flatSrcNode() method behaves like the srcNode() method.

The example below prints the source inside the group, and the source outisde the group of the currently selected node if it is in a group and has a source.

function sourceFinder()
{
  var myNode = selection.selectedNode(0);
  var parentNode = node.parentNode(myNode);

  if (node.isGroup() && node.isLinked(myNode, 0))
  {
    var source = node.srcNode(myNode, 0);
    var flatSource = node.flatSrcNode(myNode, 0);
    MessageLog.trace("Source inside the group: " + source);
    if( source != flatSource )
      MessageLog.trace("Source outside the group: " + flatSource);
  }
}

Parameters

node	: The path of the node.
iPort	: The port number on the destination node whose source node you want to find. This value is between 0 and the results of the numberOfInputPorts() method, minus one.

Returns

If the Source node is a Group, this method returns the path of the node inside the Group node that is the source. If the source is not inside a group, the flatSrcNode() method behaves like the srcNode() method.

subNodeByName

String node::subNodeByName ( String &  parent, String  name  )

slot

Returns the full path of a child node belonging to a parent group.

The existence of the parent group is validated as well as the existence of the child node in that parent. Use this method instead of manually concatenating the full path name of child nodes. The example below deconstructs and then rebuilds a node path using subNodeByName. exNode is the full name of a node, such as "Top/MyGroup/MyNode".

var name = node.getName(exNode);
var parent = node.parentNode(exNode);

//With both the parent path and the node name, you can rebuild the original node with subNodeByName
var rebuiltNode = node.subNodeByName(parent,exNode);
//This rebuilt node will be equal to the original node
MessageLog.trace(node.equals(exNode, rebuiltNode)); //This will print true

Parameters

parent	: Fully qualified path of the parent group.
name	: The actual node name suffix. This one is only the short name, not the full path of the node.

Returns

Returns the full path of a child node belonging to a parent group.

subNodes

QScriptValue node::subNodes ( String &  parentGroup )

slot

Returns an array of sub nodes.

The example below prints an array of a node's subnodes if the node's type is GROUP. exNode is the full name of a node, such as "Top/MyGroup".

function groupInfo( exNode )
{
  var i = 0;
  if (node.type(exNode) == GROUP)
  {
    MessageLog.trace("The node " + exNode + " has " + node.numberOfSubNodes(exNode) + " sub nodes.");
    while(i < node.numberOfSubNodes(exNode))

function insertPeg()
{
  var myNode = selection.selectedNode(0);
  var parentNode = node.parentNode(myNode);

  var newPeg = node.add(parent, "New Peg", "PEG", 0, -50, 0);
  var myNodeDestination = node.dstNode(myNode, 0 , 0);

  if (node.isLinked(myNode, 0))
  {
    node.unlink(myNodeDestination, 0);
