Lookup

Lookups serve for fast data searching in lists of key-value type. They can subsequently be localized and used in pipeline objects (processors and the like). Each lookup requires a statically or dynamically created value list.

If the “lazy” parameter in the constructor is set to True, no load method is called and the user is expected to call it when necessary.

class Lookup(app, id=None, config=None, lazy=False)[source]

Bases: Configurable

Description:

Returns

__init__(app, id=None, config=None, lazy=False)[source]: Description:

Lookup construction

Lookup.__getitem__(key)[source]

Lookup.__iter__()[source]

Lookup.__len__()[source]

Lookup.__contains__(item)[source]

Lookup._create_provider(path: str)[source]

Description:

Returns

Lookup.time()[source]

Description:

Returns: time

Lookup.ensure_future_update(loop)[source]

Description:

MappingLookup

class MappingLookup(app, id=None, config=None, lazy=False)[source]

Bases: Lookup, Mapping

Description:
