Data Types

Data Types

The high-level API (Adapter, Target, Commander, AemStream) returns typed values defined in pycommander_core.types. Exceptions live in pycommander_core.errors (see Error-Handling).

from pycommander_core.types import (
    AdapterInfo, AdapterVoltageInfo, VcomHandshake, CtuneValue, TargetInfo, AemMeasurement,
)

Unless noted otherwise, most fields default to None, since Commander does not always populate every field for every device.

Result tuples

A few namedtuples model raw command results:

• CommanderResult(returncode, stdout, stderr) — returned by Commander.runCommand(..., json_formatted_output=False). Exported from the top-level package as CommanderResult.
• CommandResult(returncode, output) — internal result of a single command-suite call.
• RunnerResult(returncode, stdout, stderr) — internal result from the subprocess Runner.
