qiskit.dagcircuit.DAGNode
class DAGNode(type=None, op=None, name=None, qargs=None, cargs=None, condition=None, wire=None, nid=- 1)
Object to represent the information at a node in the DAGCircuit.
It is used as the return value from *_nodes() functions and can be supplied to functions that take a node.

Methods
__init__([type, op, name, qargs, cargs, …]) | Create a node |
semantic_eq(node1, node2) | Check if DAG nodes are considered equivalent, e.g., as a node_match for nx.is_isomorphic. |
Attributes
cargs | |
condition | |
name | |
op | Returns the Instruction object corresponding to the op for the node, else None |
qargs | Returns list of Qubit, else an empty list. |

type | |
wire | Returns the Bit object, else None. |
