BaseTarget

~~abstract~~ ~~class~~ ~~BaseTarget~~<Z> : ~~Target~~<R>

A base Target for loading com.bumptech.glide.load.engine.Resources that provides basic or empty implementations for most methods.

For maximum efficiency, clear this target when you have finished using or displaying the com.bumptech.glide.load.engine.Resource loaded into it using clear.

For loading com.bumptech.glide.load.engine.Resources into android.view.Views, com.bumptech.glide.request.target.ViewTarget or are preferable.

Deprecated

Use CustomViewTarget if loading the content into a view, the download API if in the background (http://bumptech.github.io/glide/doc/getting-started.html#background-threads), or a a fully implemented Target for any specialized use-cases. Using BaseView is unsafe if the user does not implement onLoadCleared, resulting in recycled bitmaps being referenced from the UI and hard to root-cause crashes.
