AnalysisPass
class AnalysisPass(*args, **kwargs)
Bases: qiskit.transpiler.basepasses.BasePass
An analysis pass: change property set, not DAG.
Methods
name
AnalysisPass.name()
Return the name of the pass.
run
abstract AnalysisPass.run(dag)
Run a pass on the DAGCircuit. This is implemented by the pass developer.
Parameters
dag (DAGCircuit) – the dag on which the pass is run.
Raises
NotImplementedError – when this is left unimplemented for a pass.
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).
