@Manual(literal=".at(when,event)", hint="used to send messages to other agents", argsHint={"the time for the event to be generated","the event to be created"}, argsType={"string","trigger term"}, examples={".at(\"now +3 minutes\", {+!g}): generates the event +!g 3 minutes from now.",".at(\"now +1 m\", {+!g})",".at(\"now +2 h\", {+!g})"}, seeAlso="jason.stdlib.wait") public class at extends DefaultInternalAction
Internal action: .at
.
Description: creates an event at some time in the future. This command is based on the unix "at" command, although not fully implemented yet.

The syntax of this string in the current implementation has the following format:
now + <number> [<time_unit>]
- + event (trigger term): the event to be created. The event should follow the Jason Syntax for event and be enclosed by { and }.
Examples:
-
.at("now +3 minutes", {+!g})
: generates the event+!g
3 minutes from now. -
.at("now +1 m", {+!g})
-
.at("now +2 h", {+!g})
