PersistentBinaryDataCache

public PersistentBinaryDataCache(@NotNull
                                 File dir)

PersistentBinaryDataCache

public PersistentBinaryDataCache(@NotNull
                                 File dir,
                                 int maxElementsInMemory,
                                 int maxElementsOnDisk,
                                 int timeToLiveSeconds)

Method Detail

put

public void put(@NotNull
                String key,
                @Nullable
                InputStream stream)

Description copied from interface: BinaryDataCache

Stores the data presented by the stream object for the given key. The caller is responsible for closing the stream.

Specified by:

put in interface BinaryDataCache

Parameters:

key - the key

stream - the data stream. Null is acceptable.

putBytes

public void putBytes(@NotNull
                     String key,
                     @Nullable
                     byte[] bytes)

Description copied from interface: BinaryDataCache

Stores the data presented by the byte array for the given key. Using BinaryDataCache.put(String, java.io.InputStream) is preferable unless you have binary data in memory.

Specified by:

putBytes in interface BinaryDataCache

Parameters:

key - the key

bytes - the data. Null is acceptable.

hasEntry

public boolean hasEntry(@NotNull
                        String key)

Description copied from interface: BinaryDataCache

Whether some value with the key is present in the cache

Specified by:

hasEntry in interface BinaryDataCache

Parameters:

key - the key

Returns:

true if present (even null) and false otherwise

get

@Nullable
public BinaryDataCache.Entry get(@NotNull
                                 String key)

Description copied from interface: BinaryDataCache

Returns the content element associated with the key.

Specified by:

get in interface BinaryDataCache

Parameters:

key - the key

Returns:

the element or null if no entry is present in the cache.

getKeys

@NotNull
public Collection<String> getKeys()

invalidate

public void invalidate(@NotNull
                       String key)

Description copied from interface: BinaryDataCache

Invalidates the data associated with the key.

Specified by:

invalidate in interface BinaryDataCache

Parameters:

key - the key

shutdown

public void shutdown()

flush

public void flush()
