Event Handlers Python Module

Event handlers module.

This module contains classes for handling the events. Users of this library should create their own instances of the abstract class EventHandler to process on the downloaded data.

class pacifica.dispatcher.event_handlers.EventHandler

Event handler abstract class.

This class defines the interface for handling a cloud event.

_abc_cache = <_weakrefset.WeakSet object>

_abc_negative_cache = <_weakrefset.WeakSet object>

_abc_negative_cache_version = 42

_abc_registry = <_weakrefset.WeakSet object>

handle(event: cloudevents.model.Event) → None

Abstract method for event handling.

This method is called to process data after download.

class pacifica.dispatcher.event_handlers.NoopEventHandler

The Noop event handler class.

This class is a stub that does nothing when an event is received. This class maybe useful if the act of downloading and uploading is desired with no processing.

_abc_cache = <_weakrefset.WeakSet object>

_abc_negative_cache = <_weakrefset.WeakSet object>

_abc_negative_cache_version = 42

_abc_registry = <_weakrefset.WeakSet object>

handle(event: cloudevents.model.Event) → None

Method does nothing, intentionally.

class pacifica.dispatcher.event_handlers.ExceptionEventHandler

The exception event handler class.

This class is a stub that raises an exception when an event is received. This class is useful for testing error handling in the overall workflow.

_abc_cache = <_weakrefset.WeakSet object>

_abc_negative_cache = <_weakrefset.WeakSet object>

_abc_negative_cache_version = 42

_abc_registry = <_weakrefset.WeakSet object>

handle(event: cloudevents.model.Event) → None

Method raises an exception, because you are bad.
