DatastoreRenderer class

High-performance tile renderer for datastore-based map data.

This renderer converts map data from datastores into visual tile representations by applying rendering themes and generating bitmap images. It supports both static rendering (with labels) and dynamic rendering (without labels for rotation).

Key features:

  • Efficient tile-based rendering with object pooling
  • Theme-based styling with zoom level support
  • Optional label rendering for rotation compatibility
  • Spatial indexing for collision detection
  • Performance optimizations with caching

Methods

dispose() → void
Disposes of renderer resources and cleans up.
override
executeJob(JobRequest job) → Future<JobResult>

override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
retrieveLabels(JobRequest job) → Future<JobResult>
Retrieves labels for separate rendering to support map rotation.
override
supportLabels() → bool
Returns whether this renderer supports separate label rendering.
override
toString() → String
A string representation of this object.
