+Event Name
+##########
+
+ .. container:: paragraph
+
+ Any event defined in APEX has to be unique. The "name" of
+ of an event is used as an identifier for an ApexEvent. Every
+ event has to be tagged to an eventName. This can be done in different
+ ways. Either the actual event can have a field called "name". Or, the
+ event has some other field that can act as the identifier, which can be
+ specified using "nameAlias". But in other cases, where a "name" or "nameAlias"
+ cannot be specified, the incoming event coming over an endpoint can be
+ manually tagged to an "eventName" before consuming it.
+
+ .. container:: paragraph
+
+ The "eventName" can have a single event's name if the event coming
+ over the endpoint has to be always mapped to the specified eventName's
+ definition. Otherwise, if different events can come over the endpoint,
+ then "eventName" field can consist of multiple event names separated by
+ "|" symbol. In this case, based on the received event's structure, it is
+ mapped to any one of the event name specified in the "eventName" field.
+
+ .. container:: paragraph

REST Requestor IO

.. container:: paragraph
APEX can act as REST requestor on the input as well as on
the output interface. The media type is
``application/json``, so this plugin only works with
- the JSON Event protocol.
+ the JSON Event protocol. This plugin allows APEX to send REST requests
+ and to receive the reply of that request without tying up APEX resources
+ while the request is being processed. The REST Requestor pairs a REST
+ requestor producer and consumer together to handle the REST request
+ and response. The REST request is created from an APEX output event
+ and the REST response is input into APEX as a new input event.

-The APEX REST Editor
---------------------
-
- .. container:: paragraph
-
- The standard way to use the APEX REST Editor is via an
- installation of the *war* file on a webserver. However, the
- REST editor can also be started via command line. This will
- start a Grizzly webserver with the *war* deployed. Access to
- the REST Editor is then via the provided URL
-
- .. container:: paragraph
-
- On UNIX and Cygwin systems use:
-
- .. container:: ulist
-
- - ``apexRESTEditor.sh`` - simply starts the webserver with
- the REST editor
-
- - ``apexApps.sh rest-editor`` - simply starts the webserver
- with the REST editor
-
- .. container:: paragraph
-
- On Windows systems use:
-
- .. container:: ulist
-
- - ``apexRESTEditor.bat`` - simply starts the webserver with
- the REST editor
-
- - ``apexApps.bat rest-editor`` - simply starts the
- webserver with the REST editor
