Detailed Description

A single computation graph node. Owned exclusively by its ComputationGraph (see computation_graph.hpp); parent/child edges here are non-owning raw pointers into nodes the same graph owns.

Note

Nodes never expose a way to remove an edge or reset parents/children to empty – this is deliberate. ComputationGraph's persistence guarantee (graph survives past the backward pass, Mission 3) depends on nothing anywhere in this codebase being able to silently discard graph structure.

Constructor & Destructor Documentation

Node()

pulsatrix::Node::Node ( NodeId  id, OpType  op_type, Shape  shape, std::optional< std::string >  label = std::nullopt  )

inline

Constructs a node.

Parameters

id	This node's stable identifier, assigned by the owning ComputationGraph.
op_type	The operation category this node represents.
shape	This node's output shape.
label	Optional human-readable label (e.g. a layer name), for debugging/display.

Member Function Documentation

add_child()

void pulsatrix::Node::add_child ( Node *  child )

inline

Registers child as a child of this node. Non-owning; child must outlive this node.

add_parent()

void pulsatrix::Node::add_parent ( Node *  parent )

inline

Registers parent as a parent of this node. Non-owning; parent must outlive this node.

children()

const std::vector< Node * > & pulsatrix::Node::children ( ) const

inline

This node's child nodes.

id()

NodeId pulsatrix::Node::id ( ) const

inline

label()

const std::optional< std::string > & pulsatrix::Node::label ( ) const

inline

op_type()

OpType pulsatrix::Node::op_type ( ) const
