# CountOpsLongestPath¶

class CountOpsLongestPath(*args, **kwargs)[source]

Bases: qiskit.transpiler.basepasses.AnalysisPass

Count the operations on the longest path in a DAGcircuit.

The result is saved in property_set['count_ops_longest_path'] as an integer.

Methods

 name Return the name of the pass. run Run the CountOpsLongestPath pass on dag.

Attributes

is_analysis_pass

Check if the pass is an analysis pass.

If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.

is_transformation_pass

Check if the pass is a transformation pass.

If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).
