Reports whether a filter assembled for a loader has nothing left to look up, so the loader can be skipped.

**Signature:**

```typescript
static isEmptyArg(filter: any): boolean;
```

## Parameters


| Parameter | Type | Description |
| --- | --- | --- |
| filter | any | the filter value to test |


**Returns:**

boolean

`true` when there is nothing left to fetch

## Remarks

This is the test that keeps a query from making pointless round trips: once the ids already in the request's resolution cache have been removed from a filter, what remains may be nothing at all, and the dependency is then satisfied from the cache instead of by a call.

"Empty" is looser than falsy, and worth knowing precisely if you write your own filters. An array is empty when it has no elements. A plain object is empty when every one of its own properties is either falsy or an empty array — so `{}` and `{ ids: [] }` both count as empty, while `{ ids: [1] }` does not. Anything else is empty when it is falsy.
