Examples with Request com.bumptech.glide.request.Request used on opensource projects

Example 1 with Request

use of com.bumptech.glide.request.Request in project glide by bumptech.

the class ViewTarget method getRequest.

/**
   * Returns any stored request using {@link android.view.View#getTag()}.
   *
   * <p> For Glide to function correctly, Glide must be the only thing that calls {@link
   * View#setTag(Object)}. If the tag is cleared or put to another object type, Glide will not be
   * able to retrieve and cancel previous loads which will not only prevent Glide from reusing
   * resource, but will also result in incorrect images being loaded and lots of flashing of images
   * in lists. As a result, this will throw an {@link java.lang.IllegalArgumentException} if {@link
   * android.view.View#getTag()}} returns a non null object that is not an {@link
   * com.bumptech.glide.request.Request}. </p>

@Override
@Nullable
public Request getRequest() {
    Object tag = getTag();
    Request request = null;

        if (tag instanceof Request) {
            request = (Request) tag;
        } else {
            throw new IllegalArgumentException("You must not call setTag() on a view Glide is targeting");
        }
    }
    return request;

Example 2 with Request

    Request request = mock(Request.class);
    target.setRequest(request);
    ViewTarget<View, Object> second = new TestViewTarget(view);

Example 3 with Request

    loader = createGifFrameLoader(null);
    DelayTarget previous = mock(DelayTarget.class);
    Request previousRequest = mock(Request.class);
