Detailed Description

This object supervises the traversal of the data graph and the moving of data from one DataNode to its children.

The data graph is used to manage data from input devices, etc. See the overview of the data graph in dataNode.h.

◆ collect_leftovers()

void DataGraphTraverser::collect_leftovers ( )

Pick up any nodes that didn't get completely traversed.

These must be nodes that have multiple parents, with at least one parent completely outside of the data graph.

◆ get_current_thread()

Thread * DataGraphTraverser::get_current_thread ( ) const

inline

Returns the currently-executing thread object, as passed to the DataGraphTraverser constructor.

Definition at line 19 of file dataGraphTraverser.I.

◆ traverse()

void DataGraphTraverser::traverse ( PandaNode * node )

Starts the traversal of the data graph at the indicated root node.

◆ traverse_below()

void DataGraphTraverser::traverse_below	(	PandaNode *	node,
		const DataNodeTransmit &	output
	)

Continues the traversal to all the children of the indicated node, passing in the given data, without actually calling transmit_data() on the given node.
