方法详细资料

generateKey

public static String generateKey(String imageUri,
                                 ImageSize targetSize)

Generates key for memory cache for incoming image (URI + size).
Pattern for cache key - [imageUri]_[width]x[height].

createFuzzyKeyComparator

public static Comparator<String> createFuzzyKeyComparator()

findCachedBitmapsForImageUri

public static List<android.graphics.Bitmap> findCachedBitmapsForImageUri(String imageUri,
                                                                         MemoryCache memoryCache)

Searches all bitmaps in memory cache which are corresponded to incoming URI.
Note: Memory cache can contain multiple sizes of the same image if only you didn't set denyCacheImageMultipleSizesInMemory() option in configuration

findCacheKeysForImageUri

public static List<String> findCacheKeysForImageUri(String imageUri,
                                                    MemoryCache memoryCache)

Searches all keys in memory cache which are corresponded to incoming URI.
Note: Memory cache can contain multiple sizes of the same image if only you didn't set denyCacheImageMultipleSizesInMemory() option in configuration

removeFromCache

public static void removeFromCache(String imageUri,
                                   MemoryCache memoryCache)

Removes from memory cache all images for incoming URI.
Note: Memory cache can contain multiple sizes of the same image if only you didn't set denyCacheImageMultipleSizesInMemory() option in configuration
