Public Functions

~FlowGraph() override = default

virtual void add_operator(const NodeType &op) override

Add a node to the graph.

Parameters

op – The node to add.

virtual void add_flow(const NodeType &op_u, const NodeType &op_v, const EdgeDataType &port_map) override

Add an edge to the graph.

Parameters

• op_u – A source operator.

• op_v – A destination operator.

• port_map – A map from the source operator’s port name to the destination operator’s port name(s).

virtual std::optional<EdgeDataType> get_port_map(const NodeType &op_u, const NodeType &op_v) override

Get a mapping from the source operator’s port name to the destination operator’s port name(s).

Parameters

• op_u – A source operator.

• op_v – A destination operator.

Returns

A map from the source operator’s port name to the destination operator’s port name(s).

virtual bool is_root(const NodeType &op) override

Check if the operator is a root operator.

Parameters

op – A node in the graph.

Returns

true if the operator is a root operator.

virtual bool is_leaf(const NodeType &op) override

Check if the operator is a leaf operator.

Parameters

op – A node in the graph.

Returns

true if the operator is a leaf operator.

virtual std::vector<NodeType> get_root_operators() override

Get all root operators.

Returns

A vector of root operators.

virtual std::vector<NodeType> get_operators() override

Get all operators.

Returns

A vector of all operators.

virtual std::vector<NodeType> get_next_operators(const NodeType &op) override

Get the next operators of the given operator.

Parameters

op – A node in the graph.

Returns

A vector of next operators.
