koi_net.components.interfaces.knowledge_handler

Classes

`HandlerType`(*values)	Types of handlers used in knowledge processing pipeline.
`KnowledgeHandler`(log, pipeline)	Base class for knowledge processing pipeline handler components.
`StopChain`()	Class for STOP_CHAIN sentinel returned by knowledge handlers.

class koi_net.components.interfaces.knowledge_handler.HandlerType(*values)[source]

Bases: StrEnum

Types of handlers used in knowledge processing pipeline.

See KnowledgePipeline for the differences between handler types.

Bundle = 'bundle'

Final = 'final'

Manifest = 'manifest'

Network = 'network'

RID = 'rid'

class koi_net.components.interfaces.knowledge_handler.KnowledgeHandler(log, pipeline)[source]

Bases: object

Base class for knowledge processing pipeline handler components.

Derived classes MUST define the class variable handler_type, and may optionally set rid_types and event_types, to limit when, and which kind of knowledge objects will be passed to this handler.

Parameters:

log (Logger)
pipeline (KnowledgePipeline)

event_types: tuple[EventType | None] = ()

handle(kobj)[source]

Return type:: KnowledgeObject | None | StopChain
Parameters:: kobj (KnowledgeObject)

handler_type: HandlerType

log: Logger

pipeline: KnowledgePipeline

rid_types: tuple[RIDType] = ()

class koi_net.components.interfaces.knowledge_handler.StopChain[source]

Bases: object

Class for STOP_CHAIN sentinel returned by knowledge handlers.
