Class used to create the operation graph to be printed in the dot representation.

This represent a single node of the overall graph. Each node maps the real RNode keeping just the name and the columns defined up to that point.

Member Data Documentation

◆ fColor

std::string ROOT::Internal::RDF::GraphDrawing::GraphNode::fColor

private

Definition at line 51 of file GraphNode.hxx.

◆ fDefinedColumns

std::vector<std::string> ROOT::Internal::RDF::GraphDrawing::GraphNode::fDefinedColumns

private

Columns defined up to this node.

By checking the defined columns between two consecutive nodes, it is possible to know if there was some Define in between.

Definition at line 55 of file GraphNode.hxx.

◆ fID

unsigned int ROOT::Internal::RDF::GraphDrawing::GraphNode::fID

private

Nodes may share the same name (e.g.

Filter). To manage this situation in dot, each node is represented by an unique id.

Definition at line 49 of file GraphNode.hxx.

◆ fIsExplored

bool ROOT::Internal::RDF::GraphDrawing::GraphNode::fIsExplored = false

private

When the graph is reconstructed, the first time this node has been explored this flag is set and it won't be explored anymore.

Definition at line 61 of file GraphNode.hxx.

◆ fIsNew

bool ROOT::Internal::RDF::GraphDrawing::GraphNode::fIsNew = true

private

A just created node.

This means that in no other exploration the node was already created (this is needed because branches may share some common node).

Definition at line 65 of file GraphNode.hxx.

◆ fName

std::string ROOT::Internal::RDF::GraphDrawing::GraphNode::fName

private

Definition at line 51 of file GraphNode.hxx.

◆ fPrevNode

std::shared_ptr<GraphNode> ROOT::Internal::RDF::GraphDrawing::GraphNode::fPrevNode

private

Definition at line 57 of file GraphNode.hxx.

◆ fShape

std::string ROOT::Internal::RDF::GraphDrawing::GraphNode::fShape

private

Definition at line 51 of file GraphNode.hxx.
