volumential.wranglers.nearfield_cache

Device-resident near-field table payload cache.

Both wrangler backends upload the same combined table arrays to the device and keep a small LRU of them keyed by table identity; this mixin owns that upload-and-cache step.

class volumential.wranglers.nearfield_cache.NearFieldPayloadCacheMixin

Bases: object

Uploads and caches combined near-field table data on the device.

Expects the host class to provide _nearfield_device_payload_cache (an collections.OrderedDict) and _nearfield_device_payload_cache_max.
