WorldWind Kotlin/earth.worldwind.render.image/ImageSource/[jvm]NetworkBoundImageFactory

NetworkBoundImageFactory

interface NetworkBoundImageFactory : ImageSource.ImageFactory

An ImageFactory whose bytes may come from a local cache OR the network. The render resource cache decodes it in two phases: createCachedImage on the local-retrieval lane (cache-only, null on a miss) then createImage on the remote lane only on a miss — keeping slow network fetches off the lane shared with placemark icons and cache-hit tiles.

Properties

isRunBlocking

open val isRunBlocking: Boolean

Image factory runs asynchronously by default, but this behavior can be changed by overriding current attribute.

Functions

createCachedImage

abstract suspend fun createCachedImage(): BufferedImage?

Cache-only decode; returns null on a local miss WITHOUT touching the network.

createImage

abstract suspend fun createImage(): BufferedImage?

Returns the image associated with this factory. This method may be called more than once and may be called from a non-UI thread. Each invocation must return an image with equivalent content, dimensions and configuration. Any side effects applied to the WorldWind scene by the factory must be executed on the main thread.
