blpapi.Event

class blpapi.Event

A single event resulting from a subscription or a request.

Event objects are created by the API and passed to the application either through a registered eventHandler or EventQueue or returned either from the nextEvent() or tryNextEvent() methods. Event objects contain Message objects which can be accessed using an iteration over Event:

for message in event:
    ...

The Event object is a handle to an event. The event is the basic unit of work provided to applications. Each Event object consists of an eventType attribute and zero or more Message objects.

Event objects are always created by the API, never directly by the application.
