Usage

From source file:com.squareup.picasso3.PlatformLruCache.java

void set(@NonNull String key, @NonNull Bitmap bitmap) {
    if (key == null || bitmap == null) {
        throw new NullPointerException("key == null || bitmap == null");
    }/*from  ww w.  jav  a  2 s.  com*/

    int byteCount = BitmapCompat.getAllocationByteCount(bitmap);

    // If the bitmap is too big for the cache, don't even attempt to store it. Doing so will cause
    // the cache to be cleared. Instead just evict an existing element with the same key if it
    // exists.
    if (byteCount > maxSize()) {
        cache.remove(key);
        return;
    }

    cache.put(key, new BitmapAndSize(bitmap, byteCount));
