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.

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.

osg::Referenced* osg::ProxyNode::getDatabaseOptions ( )
inline

Get the optional database osgDB::Options object used when loaded children.

const osg::Referenced* osg::ProxyNode::getDatabaseOptions ( ) const
inline

Get the optional database osgDB::Options object used when loaded children.

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::setDatabaseOptions ( osg::Referenced options)
inline

Set the optional database osgDB::Options object to use when loaded children.

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.
