QScriptValue	buildDefaultCompositionOrder ()
	returns an array of Composition object using the current default composition order as used by the camera view or the timeline.
QScriptValue	buildCompositionOrderForDisplay (String &displayNode)
	return an array of Composition object using the specified display name.

Detailed Description

Scriptable interface for extracting the timeline composition order. var composition = composition.buildDefaultCompositionOrder() or var composition = composition.buildCompositionOrderForDisplay( displayNode );.

This builds the composition using the node_timeline internal service and return an JavaScript array of CompositionItem object.

The array returned is ordered. The first entry is the top most node in the composition order, or is a parent of nodes.

You can use it in Script Editor only.

var composition = compositionOrder.buildDefaultCompositionOrder();

for( c in composition )
{
  var compItem = composition[ c ];
  var nodeName = compItem.node;
  var nodeDepth = compItem.depth;
  var enabledNode =  ( node.getEnable( nodeName) == true );
  var nodeType = node.type(nodeName);

  System.println(  "Exporting node: " + nodeName + " at depth: " + nodeDepth );

  // node at root depth
  if( nodeDepth == 0 )
  {
   // do something for a root node here
  }
  else
  {
    // do something for an inner node.
  }
  if( nodeType == "PEG")
  {
    // do something for a PEG module
  }
  else if( nodeType == "READ" )
  {
    // do something for READ module
  }
 }
}

QScriptValue compositionOrder::buildCompositionOrderForDisplay ( String &  displayNode )

slot

return an array of Composition object using the specified display name.

This method is similar to buildDefaultCompositionOrder(), howeer, instead of working with the current display, it requires a display module. This method can be used to generate the composition order from any display module in the project

QScriptValue compositionOrder::buildDefaultCompositionOrder ( )

slot

returns an array of Composition object using the current default composition order as used by the camera view or the timeline.

Using the current display, return the tree-like composition as normally returned by the internal node_timeline service. This method return the "Display All" composite order.

The depth of each Comosition can be used to find the parent-child. Top level nodes or parentless nodes have a depth at 0. Child of this node will have a depth 1 level greater. Nodes that are at the same depth,
