Member Function Documentation

bool ReNodeAlgo::operator() ( ReNode & n ) [pure virtual]

This gets called for each regexp node during the traversal. If for some reason continuing the traversal becomes unnecessary, the operator should return false. If it should continue with the rest of the unvisited nodes, it should return true. Reimplemented in LeafNumberGen, FollowPosGen, LeafFinder, and AttributeGen.
