Detailed Description

A visitor to locate nodes in a scene-graph.

This visitor traverses the scene-graph looking for osgSim::DOFTransform nodes. When it locates a DOF node, the pointer to the DOF for is saved in a list for later use.

Constructor & Destructor Documentation

DOFFinder::DOFFinder

(

)

CTOR.

virtual DOFFinder::~DOFFinder ( )

protectedvirtual

DTOR.

Protected destructor prevents direct deletion or creation on stack.

Member Function Documentation

virtual void DOFFinder::apply ( osg::Node &  node )

virtual

The method applied to the node being visited.

If the node is an osgSim::DOFTransform, save a reference for later consumption.

osgSim::DOFTransform* DOFFinder::takeNextDOF

(

)

Extract a reference to one of the saved osgSim::DOFTransform nodes.

This call removes the reference of the node from this object. There is no guarantee to the order that the nodes were store or removed.

Returns

A pointer to a saved node or NULL when no more nodes are left to be removed.

int DOFFinder::dofCount

(

)

const

Gets the current count of stored DOF nodes.

Returns

The number of nodes.

Member Data Documentation

osg::NodeList DOFFinder::myNodeList

protected

DOF nodes found while traversing the graph.
