Core.point_conditions.pointIdentity

Call as

Core.point_conditions.pointIdentity(self, unit, key)

Record the dependency Core.point_conditions.pointIdentity, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.

What it does

Observes whether unit exists and, if so, its class, for the point-resource selectors. For the player it reuses a class stored in self.longtermCache under key when it was recorded against the same UnitClass function, and otherwise stores the freshly read class there.

Arguments

Name	Type	What it does
`self`	`RMAddon`	Rotation Master addon instance.
`unit`	`string`	Unit token to observe.
`key`	`any`	Long-term cache key for the player's class; only used for "player". The addon passes a private table.

Returns

1	`table \| nil`	{exists=false}, or {exists=true, class=token}; nil when unavailable.
2	`string \| nil`	The platform observer's reason for nil.

Editions

Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.

Not available on that edition (the reason is in the tooltip)
Only while Blizzard's deprecation fallbacks are on

Game API
`UnitClass`

Secret values (Retail and Forever)

On Retail and Forever the game hands addons secret values. This helper checks what it reads (addon.Platform:CanReadValue) and returns nil with a reason such as restricted-value instead of a secret it cannot compare. Treat nil as unavailable, not as false.

Example

-- needs the dependency Core.point_conditions.pointIdentity
local record, reason = Functions.cache.getCached(cache, Core.point_conditions.pointIdentity, addon, "target")
if not record then return nil, reason end
return record.exists and record.class == "ROGUE"
