| virtual bool osg::PagedLOD::addChild | ( | Node * | child | ) | [virtual] |
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.

| void osg::PagedLOD::setFrameNumberOfLastTraversal | ( | int | frameNumber | ) | [inline] |
Set the frame number of the last time that this PageLOD node was traversed.
Note, this frame number is automatically set by the traverse() method for all traversals (update, cull etc.).
| int osg::PagedLOD::getFrameNumberOfLastTraversal | ( | ) | const [inline] |
Get the frame number of the last time that this PageLOD node was traversed.
| void osg::PagedLOD::setNumChildrenThatCannotBeExpired | ( | unsigned int | num | ) | [inline] |
Set the number of children that the PagedLOD must keep around, even if they are older than their expiry time.
| unsigned int osg::PagedLOD::getNumChildrenThatCannotBeExpired | ( | ) | const [inline] |
Get the number of children that the PagedLOD must keep around, even if they are older than their expiry time.
| virtual bool osg::PagedLOD::removeExpiredChildren | ( | double | expiryTime, | |
| NodeList & | removedChildren | |||
| ) | [virtual] |
Remove the children from the PagedLOD which haven't been visited since specified expiry time.
The removed children are added to the removeChildren list passed into the method, this allows the children to be deleted later at the caller's discretion. Return true if children are removed, false otherwise.
