WoWInterface/Interface/AddOns/WeakAuras/BuffTrigger2.lua

--[=[ BuffTrigger2.lua
This file contains the "aura2" trigger for buffs and debuffs. It has replaced the older Bufftrigger 1, which is now gone.

It registers the BuffTrigger table for the trigger type "aura2" and has the following API:

Add(data)
Adds an aura, setting up internal data structures for all buff triggers.

LoadDisplays(id)
Loads the aura ids, enabling all buff triggers in the aura.

UnloadDisplays(id)
Unloads the aura ids, disabling all buff triggers in the aura.

UnloadAll()
Unloads all auras, disabling all buff triggers.

Delete(id)
Removes all data for aura id.

Rename(oldid, newid)
Updates all data for aura oldid to use newid.

Modernize(data)
Updates all buff triggers in data.

#####################################################
# Helper functions mainly for the WeakAuras Options #
#####################################################

CanHaveDuration(data, triggernum)
Returns whether the trigger can have a duration.

GetOverlayInfo(data, triggernum)
Returns a table containing all overlays. Currently there aren't any

CanHaveClones(data, triggernum)
Returns whether the trigger can have clones.

CanHaveTooltip(data, triggernum)
Returns the type of tooltip to show for the trigger.

GetNameAndIcon(data, triggernum)
Returns the name and icon to show in the options.

GetAdditionalProperties(data, triggernum)
Returns the tooltip text for additional properties.

GetTriggerConditions(data, triggernum)
Returns the potential conditions for a trigger
