public final class SetSourceSectionVisitor
extends DepthFirstTraversalRegexASTVisitor

This visitor is used for setting the SourceSection of AST subtrees that are copied into the parser tree as substitutions for things like word boundaries and position assertions in multi-line mode. It will set the source section of all nodes in the subtree to the SourceSection object passed to SetSourceSectionVisitor.run(Group, Token).
