Class EventHandler (1.42.0) 

EventHandler(mapping=None, *, ignore_unknown_fields=False, **kwargs)

An event handler specifies an event that can be handled during a session. When the specified event happens, the following actions are taken in order:

  • If there is a [trigger_fulfillment][google.cloud.dialogflow.cx.v3.EventHandler.trigger_fulfillment] associated with the event, it will be called.
  • If there is a [target_page][google.cloud.dialogflow.cx.v3.EventHandler.target_page] associated with the event, the session will transition into the specified page.
  • If there is a [target_flow][google.cloud.dialogflow.cx.v3.EventHandler.target_flow] associated with the event, the session will transition into the specified flow.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
