public interface Virtualizable

This interface allows a node to convey information about what its effect would be if some of its inputs were virtualized. The virtualize(VirtualizerTool) method will only be called for nodes that have some interaction with virtualized nodes. However, the virtualized nodes might have been re-materialized in the meantime.

Method Summary

Modifier and Type	Method and Description
void	virtualize(VirtualizerTool tool) A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized.

Method Detail

virtualize

void virtualize(VirtualizerTool tool)

A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized. All modifications must be made through the supplied tool, and not directly on the node, because by the time this method is called the virtualized/non-virtualized state is still speculative and might not hold because of loops, etc.

Parameters:

tool - the tool used to describe the effects of this node
