Member Function Documentation

void proland::SceneVisitor::accept	(	ptr< TileLayer >	l,
		set< ptr< TileCache > > &	caches
	)			`[private]`

Makes this visitor visit the given tile layer, and all its referenced producers, recursively.

Parameters:

	l	the TileLayer to visit.
`[in,out]`	caches	the TileCache found during this visit.

void proland::SceneVisitor::accept	(	ptr< TileProducer >	p,
		set< ptr< TileCache > > &	caches
	)			`[private]`

Makes this visitor visit the given tile producer, and all its referenced producers, recursively.

Parameters:

	p	the TileProducer to visit.
`[in,out]`	caches	the TileCache found during this visit.

void proland::SceneVisitor::accept	(	ptr< SceneNode >	n,
		set< ptr< TileCache > > &	caches
	)			`[private]`

Makes this visitor visit the given scene node, and all its subnodes.

Parameters:

	n	the SceneNode to visit.
`[in,out]`	caches	the TileCache found during this visit.

void proland::SceneVisitor::accept ( ptr< SceneNode > root )

Makes this visitor visit the given scene graph.

This method calls the visitXxx methods for each scene node, uniform, scene node field, scene node method, tile producer, tile layer, and tile cache encountered during the recursive exploration of the given scene graph.

Parameters:

root

the scene graph to visit.

virtual ptr<SceneVisitor> proland::SceneVisitor::visitCache ( ptr< TileCache > cache ) [virtual]

Visits a TileCache.
