Package org.mapsforge.map.rendertheme.rule

Class RenderThemeFuture

  • All Implemented Interfaces:
    java.lang.Runnable, java.util.concurrent.Future<RenderTheme>, java.util.concurrent.RunnableFuture<RenderTheme>
    public class RenderThemeFuture
extends java.util.concurrent.FutureTask<RenderTheme>
    A RenderThemeFuture implements a asynchronous parsing of an XmlRenderTheme in order to move the delay caused by parsing the XML file off the user interface thread in mapsforge application. The RenderThemeFuture is reference counted to make it shareable between threads. Each thread that uses the RenderThemeFuture to retrieve a rendertheme should first call incrementRefCount to ensure that the RenderTheme does not get destroyed while the thread is waiting for execution.
