Method Detail

generateKey

public static String generateKey(String imageUri,
                                 ImageSize targetSize)

Generates key for memory cache for incoming image (URI + size).
Pattern for cache key - , where (1) - image URI, (2) - image size ([width]x[height]).

createFuzzyKeyComparator

public static Comparator<String> createFuzzyKeyComparator()

findCachedBitmapsForImageUri

public static List<android.graphics.Bitmap> findCachedBitmapsForImageUri(String imageUri,
                                                                         MemoryCacheAware<String,android.graphics.Bitmap> 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,
                                                    MemoryCacheAware<String,android.graphics.Bitmap> 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,
                                   MemoryCacheAware<String,android.graphics.Bitmap> 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
