query · in the family Device peripheral

What it does

The device peripheral list — each entry is a device peripheral — a printer, scanner, or card reader on a device.

The caller's org-group family's ACTIVE LISTING of DevicePeripherals — doomed records DROP from listings. PAGINATED: limit clamps to [1, 200], default 100; nextToken = the prior page's cursor, verbatim — opaque + tenant-bound (a malformed or foreign token → VALIDATION/INVALID). Walk until nextToken is null (a page may hold fewer than limit — doomed drop per page). STRUCTURED FILTER + SORT: filter = AND across clauses, OR within a clause's values; sort = one declared field, asc/desc. The declared DevicePeripheral roster: caption (text) · status (enum) · parentId (ref) · peripheralType (enum) · model (enum) · connection (enum) · readerRef (text) · createdAt (date) · updatedAt (date). An illegal filter/sort refuses VALIDATION/INVALID NAMING the exact problem (an unknown field teaches the roster). A filtered/sorted read evaluates the WHOLE family server-side, returns the EXACT matchCount, and its nextToken binds to THE ONE filter+sort that minted it — replaying it under a different filter/sort refuses. Absent both, the unfiltered lane is unchanged (matchCount null).

What happens

Reads only — changes nothing.

Who may call it

Capability area: Reading your records — Looking up and listing the records of your organization.

Arguments

NameTypeRequiredNotes
filterFilterInputnoWhich records to answer — clauses over the family’s filterable fields (the FilterInput type and the paging guide carry the grammar).
sortSortInputnoThe order to answer in — one declared field and a direction (the SortInput type carries the grammar).
limitIntnoHow many records to answer at most; a page may hold fewer.
nextTokenStringnoThe cursor from the previous page, passed back exactly as received.

Returns

DevicePeripheralPage DevicePeripheralPage! — One page of the devicePeripherals listing — the records + the opaque resume cursor.

This is a page: items holds the records and nextToken the cursor for the next page — pass it back verbatim until it is null. See paging.
