DAGNode#

class qiskit.dagcircuit.DAGNode(nid=-1)[source]#

Bases: object

Parent class for DAGOpNode, DAGInNode, and DAGOutNode.

Create a node

Methods

static semantic_eq(node1, node2, bit_indices1, bit_indices2)[source]#

Check if DAG nodes are considered equivalent, e.g., as a node_match for rustworkx.is_isomorphic_node_match().

Parameters:

  • node1 (DAGOpNode, DAGInNode, DAGOutNode) -- A node to compare.

  • node2 (DAGOpNode, DAGInNode, DAGOutNode) -- The other node to compare.

  • bit_indices1 (dict) -- Dictionary mapping Bit instances to their index within the circuit containing node1

  • bit_indices2 (dict) -- Dictionary mapping Bit instances to their index within the circuit containing node2

Returns:

If node1 == node2

Return type:

Bool
