Method Summary

static MappingDocument	extractSourceNodes(MappingDocument doc) This visitor will extract the 'source' property off of the all the base nodes and create a separate MappingSource node and make the original node as its immediate child.
void	visit(MappingBaseNode baseNode) In this code since we are only traversing the child nodes after the modification the removal and addtion of the nodes to the current may not affect the underlying collection object.
