MemoryTileBitmapCache class

This is a memory-only implementation of the TileBitmapCache. It stores the bitmaps in memory. We use a factory and remember all active instances. This way we can easily purge caches if needed.

Methods

addTileBitmap(Tile tile, TileBitmap tileBitmap) → void
Adds a bitmap to the cache
override
dispose() → void
disposes the cache. It should not be used anymore after disposing.
override
getTileBitmapAsync(Tile tile) → Future<TileBitmap?>
override
getTileBitmapSync(Tile tile) → TileBitmap?
Returns the requested bitmap for the given Tile
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
purgeAll() → void
Purges the whole cache. The cache can be used afterwards but will not return any items
override
purgeByBoundary(BoundingBox boundingBox) → void
Purges the cache whose Tiles intersects with the given boundingBox. Any bitmap which is fully or partially intersecting the given boundingBox will be purged.
override
toString() → String
A string representation of this object.
