• LruCountingMemoryCache

Method Detail

• cache

  @Nullable() CloseableReference<V> cache(K key, CloseableReference<V> valueRef)

  Caches the given key-value pair.

  Important: the client should use the returned reference instead of the original one. It isthe caller's responsibility to close the returned reference once not needed anymore.

• cache

  @Nullable() CloseableReference<V> cache(K key, CloseableReference<V> valueRef, @Nullable() CountingMemoryCache.EntryStateObserver<K> observer)

  Caches the given key-value pair.

  Important: the client should use the returned reference instead of the original one. It isthe caller's responsibility to close the returned reference once not needed anymore.

• get

  @Nullable() CloseableReference<V> get(K key)

  Gets the item with the given key, or null if there is no such item.

  It is the caller's responsibility to close the returned reference once not needed anymore.

• inspect

  @Nullable() synchronized V inspect(K key)

• probe

   void probe(K key)

  Probes whether the object corresponding to the key is in the cache. Note that the act ofprobing touches the item (if present in cache), thus changing its LRU timestamp.

• reuse

  @Nullable() CloseableReference<V> reuse(K key)

  Gets the value with the given key to be reused, or null if there is no such value.

  The item can be reused only if it is exclusively owned by the cache.

• removeAll

   int removeAll(Predicate<K> predicate)

  Removes all the items from the cache whose key matches the specified predicate.

  Parameters:

  predicate - returns true if an item with the given key should be removed

• clear

   void clear()

  Removes all the items from the cache.

• contains

   synchronized boolean contains(Predicate<K> predicate)

  Check if any items from the cache whose key matches the specified predicate.

  Parameters:

  predicate - returns true if an item with the given key matches

• contains

   synchronized boolean contains(K key)

  Check if an item with the given cache key is currently in the cache.

  Parameters:

  key - returns true if an item with the given key matches

• trim

   void trim(MemoryTrimType trimType)

  Trims the cache according to the specified trimming strategy and the given trim type.

• getMemoryCacheParams

   MemoryCacheParams getMemoryCacheParams()

• getCachedEntries

   CountingLruMap<K, CountingMemoryCache.Entry<K, V>> getCachedEntries()

• getOtherEntries

   Map<Bitmap, Object> getOtherEntries()

• maybeEvictEntries

   void maybeEvictEntries()

  Removes the exclusively owned items until the cache constraints are met.

  This method invokes the external close method, so it must not becalled while holding the this lock.

• getCount

   synchronized int getCount()

  Gets the total number of all currently cached items.

• getSizeInBytes

   synchronized int getSizeInBytes()

  Gets the total size in bytes of all currently cached items.

• getInUseCount

   synchronized int getInUseCount()

  Gets the number of the cached items that are used by at least one client.

• getInUseSizeInBytes

   synchronized int getInUseSizeInBytes()

  Gets the total size in bytes of the cached items that are used by at least one client.

• getEvictionQueueCount

   synchronized int getEvictionQueueCount()

  Gets the number of the exclusively owned items.

• getEvictionQueueSizeInBytes

   synchronized int getEvictionQueueSizeInBytes()

  Gets the total size in bytes of the exclusively owned items.

• getDebugData

  @Nullable() synchronized String getDebugData()
