Constructor & Destructor Documentation

osg::ProxyNode::ProxyNode (  ) 
osg::ProxyNode::ProxyNode ( const ProxyNode ,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::ProxyNode::~ProxyNode (  )  [inline, protected, virtual]

Member Function Documentation

virtual bool osg::ProxyNode::addChild ( Node child  )  [virtual]

Add Node to Group. If node is not NULL and is not contained in Group then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.

Reimplemented from osg::Group.

virtual bool osg::ProxyNode::addChild ( Node child,
const std::string &  filename 
) [virtual]
virtual BoundingSphere osg::ProxyNode::computeBound (  )  const [virtual]

Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().

Reimplemented from osg::Group.

void osg::ProxyNode::expandFileNameListTo ( unsigned int  pos  )  [protected]
const vec_type& osg::ProxyNode::getCenter (  )  const [inline]

return the ProxyNode center point.

CenterMode osg::ProxyNode::getCenterMode (  )  const [inline]

Get how the center of object should be determined when computed which child is active.

const std::string& osg::ProxyNode::getDatabasePath (  )  const [inline]

Get the database path used to prepend to children's filenames.

osg::ref_ptr<osg::Referenced>& osg::ProxyNode::getDatabaseRequest ( unsigned int  childNo  )  [inline]

Return the DatabaseRequest object used by the DatabasePager to keep track of file load requests being carried on behalf of the DatabasePager. Note, in normal OSG usage you should not set this value yourself, as this will be managed by the osgDB::DatabasePager.

const osg::ref_ptr<osg::Referenced>& osg::ProxyNode::getDatabaseRequest ( unsigned int  childNo  )  const [inline]

Return the const DatabaseRequest object.

const std::string& osg::ProxyNode::getFileName ( unsigned int  childNo  )  const [inline]
LoadingExternalReferenceMode osg::ProxyNode::getLoadingExternalReferenceMode (  )  const [inline]

Get the setted mode of loading.

unsigned int osg::ProxyNode::getNumFileNames (  )  const [inline]
value_type osg::ProxyNode::getRadius (  )  const [inline]

Get the object-space radius of the volume enclosed by the ProxyNode.

osg::ProxyNode::META_Node ( osg  ,
ProxyNode   
)
virtual bool osg::ProxyNode::removeChildren ( unsigned int  pos,
unsigned int  numChildrenToRemove 
) [virtual]

Remove children from Group. Note, must be override by subclasses of Group which add per child attributes.

Reimplemented from osg::Group.

void osg::ProxyNode::setCenter ( const Vec3 center  )  [inline]

Sets the object-space point which defines the center of the osg::ProxyNode. center is affected by any transforms in the hierarchy above the osg::ProxyNode.

void osg::ProxyNode::setCenterMode ( CenterMode  mode  )  [inline]

Set how the center of object should be determined when computed which child is active.

void osg::ProxyNode::setDatabasePath ( const std::string &  path  ) 

Set the database path to prepend to children's filenames.

void osg::ProxyNode::setFileName ( unsigned int  childNo,
const std::string &  filename 
) [inline]
void osg::ProxyNode::setLoadingExternalReferenceMode ( LoadingExternalReferenceMode  mode  )  [inline]

Set how the child loading is done.

void osg::ProxyNode::setRadius ( value_type  radius  )  [inline]

Set the object-space reference radius of the volume enclosed by the ProxyNode. Used to determine the bounding sphere of the ProxyNode in the absence of any children.

virtual void osg::ProxyNode::traverse ( NodeVisitor  )  [virtual]

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Group.
