virtual void add_operator(const NodeType &op) = 0
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 &io_map) = 0
Add an edge to the graph.
- Parameters:
op_u – A source operator.
op_v – A destination operator.
io_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) = 0
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) = 0
Check if the operator is a root operator.
- Parameters:
- Returns:
op – A node in the graph.
true if the operator is a root operator.
-
virtual bool is_leaf(const NodeType &op) = 0
Check if the operator is a left operator.
- Parameters:
- Returns:
op – A node in the graph.
true if the operator is a leaf operator.
-
virtual std::vector<NodeType> get_root_operators() = 0
Get all root operators.
- Returns:
A vector of root operators.
-
virtual std::vector<NodeType> get_operators() = 0
Get all operators.
- Returns:
A vector of all operators.
-
virtual std::vector<NodeType> get_next_operators(const NodeType &op) = 0
Get the next operators of the given operator.
- Parameters:
- Returns:
op – A node in the graph.
A vector of next operators.
-
inline virtual void context(void *context)
Set the context.
- Parameters:
context – The context.
-
inline virtual void *context()
Get the context.
- Returns:
The context.
Protected Attributes
