Properties

cacheRetrievalQueueSize

var cacheRetrievalQueueSize: Int

Concurrent cache-only reads allowed. Generous vs retrievalQueueSize: cache reads are cheap local I/O and must get their own budget separate from the network-retrieval budget, so a slow network DEM fetch holding the network slots can't stall cached tiles behind it.

open override var displayName: String?

Human-readable elevation coverage name

elevationSourceFactory

var elevationSourceFactory: ElevationSourceFactory

open override var isEnabled: Boolean

Determines if current elevation coverage should be processed during rendering

retrievalQueueSize

var retrievalQueueSize: Int

Controls how many concurrent tile requests are allowed for this coverage.

override val sector: Sector

Elevation content bounding sector

var tileMatrixSet: TileMatrixSet

open override val timestamp: Long

Last elevation update timestamp

val type: String

Unique identifier of the coverage type, defined by elevation source factory content type

Functions

open override fun clear()

getElevationGrid

open override fun getElevationGrid(gridSector: Sector, gridWidth: Int, gridHeight: Int, result: FloatArray)

Gets optional user property

hasUserProperty

open override fun hasUserProperty(key: Any): Boolean

Checks optional user property exists

open override fun isChangedSince(time: Long, sector: Sector): Boolean

removeUserProperty

open override fun removeUserProperty(key: Any): Any?

Removes optional user property

setupCoverageCache

fun setupCoverageCache(capacity: Long, lowWater: Long = (capacity * 0.75).toLong())
