#LynxGenericResourceFetcher

LynxGenericResourceFetcher is defined inside LynxEngine and injected from outside to implement a general resource loading interface. It is used inside LynxEngine for resource loading capabilities of components such as Text;

#Android

#Interface Definition:

public abstract class LynxGenericResourceFetcher {
  /**
   * fetch resource with contents.
   *
   * @param request
   * @param callback contents of the requiring resource.
   */
  public abstract void fetchResource(
      LynxResourceRequest request, LynxResourceCallback<byte[]> callback);

  /**
   * fetch resource with res path.
   *
   * @param request
   * @param callback path on the disk of the requiring resource.
   */
  public abstract void fetchResourcePath(
      LynxResourceRequest request, LynxResourceCallback<String> callback);

  /**
   * fetch resource with stream.
   *
   * @param request
   * @param delegate streaming of the requiring resource.
   */
  public void fetchStream(LynxResourceRequest request, StreamDelegate delegate){};

  /**
   * cancel the request of the requiring resource.
   *
   * @param request the requiring request.
   */
  public void cancel(LynxResourceRequest request){};
}

#Method Introduction:

#fetchResource

LynxEngine internally calls this method to obtain the general resource content, and the return result is required to be the resource content byte[] type;

#fetchResourcePath

LynxEngine internally calls this method to obtain the path of the common resource on the local disk, and the return result is required to be of String type;

#fetchStream

LynxEngine internally calls this method to obtain resource content in a streaming manner;

#Injection:

Inject when constructing a LynxView using LynxViewBuilder:

LynxViewBuilder builder = new LynxViewBuilder();
builder.setGenericResourceFetcher(new GenericTemplateResourceFetcher());

Also enable this capability in LynxViewBuilder:

LynxViewBuilder builder = new LynxViewBuilder();
builder.setGenericResourceFetcher(new GenericTemplateResourceFetcher());
builder.setEnableGenericResourceFetcher(LynxBooleanOption.TRUE);

#iOS

#Interface Definition:

 * fetch resource with contents.
 *
 * @param request.
 * @param callback contents of the requiring resource.
 *
 * @return: A block which can cancel the image request if it is not finished. nil if cancel action
 * is not supported.
