/**
|
|
* Executes multiple actions in the context of the user given by the user_id.
|
|
* There are two modes of execution:
|
|
* atomic=true (default):
|
|
* All actions are validated in common, so if one action or one payload of
|
|
* one action fails, the request is aborted with an ActionException indicating
|
|
* the problematic action with both indices.
|
|
* => The whole request is handled atomically.
|
|
* atomic=false:
|
|
* Each action is validated by it's own. If there is an error, the error must
|
|
* be reported via an ActionError in the ActionsResponse. The actions result
|
|
* is not written into the Datastore. It might raise an ActionException if the
|
|
* single write request to the Datastore fails (e.g. because of locking there)
|
|
*
|
|
* For general, non specific action-related, errors an ActionException is used.
|

*

|
* @throws ActionException
