WorldWind Kotlin/earth.worldwind.layer.cache/NoOpBlobStore

NoOpBlobStore

Always-empty store. Used as the earth.worldwind.util.ContentManager.openBlobStore default on platforms that haven't implemented persistence yet, so a layer that opts into caching silently falls back to network-only without crashing.

Functions

clear

open suspend override fun clear()

Drop every entry. Schema is preserved so subsequent puts succeed.

get

open suspend override fun get(uri: String): BlobEntry?

Fetch a previously-stored blob. Null when uri is not in the cache.

put

open suspend override fun put(uri: String, bytes: ByteArray, contentType: String? = null, etag: String? = null, lastModified: Instant? = null, responseUrl: String? = null)

Persist or replace the blob for uri. contentType is whatever the server returned (e.g. application/octet-stream, model/gltf-binary); null when unknown. etag and lastModified are conditional-fetch metadata the layer can consult on a future revalidation request. responseUrl is the post-redirect URL the body was actually served from — replayed via BlobEntry.responseUrl on cache hits so callers can resolve relative URIs against the body's true origin. Null when same as uri / unknown.

remove

open suspend override fun remove(uri: String)

Drop one entry. No-op when uri is absent.

sizeBytes

open suspend override fun sizeBytes(): Long

Total stored payload size in bytes. Excludes metadata + schema overhead; close approximation suitable for budget reporting, not exact accounting.
