m3resp.SignalCollection#

class m3resp.SignalCollection(items=<factory>)[source]#

An ordered collection of Signal objects, queryable by modality.

Methods

`add`	Append signal, unless this exact object is already present.
`for_category`	Filter by physical quantity (e.g. `"airway_pressure"`).
`for_modality`	Filter by producing device/technique (e.g. `"ventilator"`).
`to_manifest_rows`

Attributes

items

Parameters:: items (list[Signal])

add(signal)[source]#

Append signal, unless this exact object is already present.

Identity (not value) equality: re-adding the same Signal instance - e.g. if it gets assembled twice on an export path - is a no-op, while two distinct results that happen to compare equal both get added.

Parameters:: signal (Signal)
Return type:: Signal

for_category(category)[source]#

Filter by physical quantity (e.g. "airway_pressure").

Independent of for_modality: a ventilator contributes several categories, and one category can come from several devices. category is matched after canonicalization, so a known alias ("paw") finds signals stored under the canonical name.
