The event library provides functions for understanding an event and the environment in which it was raised as well as actions access to event properties, a function for getting attribute values, and an action for sending events. Table of ContentsmaxLevel

event properties

The event library provides five properties:

event:domain

The value of this property is the domain which caused the rule to select.

event:name

The value of this property is the event type (or name) which caused this rule to select.

event:eid

The value of this property is the event identifier from the event to which this rule is reacting.

event:time

The value of this property is the time at which the event was received by the pico-engine.

event:attrs

The value of this property is a map of the attributes sent with the event to which this rule is reacting.

event function

event:attr

When this function is called with an attribute name, it returns the attribute value.

event action

event:send

As defined in the compatibility box above, this allows rules to send an event to another pico, whether on the same pico-engine or not.

Event Functions

Event functions in the following categories are available:

...

• event:attr() - returns a specific event attribute. The function takes the name of the attribute to be returned as its sole argument, and returns null if not found.
• event:attrs () - returns all the event attributes as a map.
