Method Detail

put

public void put(String key,
                long lifespanSeconds,
                Map<String,String> notes)

Description copied from interface: SingleUseObjectProvider

Stores the given data and guarantees that data should be available in the store for at least the time specified by {@param lifespanSeconds} parameter

Specified by:

put in interface SingleUseObjectProvider

get

public Map<String,String> get(String key)

Description copied from interface: SingleUseObjectProvider

Gets data associated with the given key.

Specified by:

get in interface SingleUseObjectProvider

Parameters:

key - String

Returns:

Map Data associated with the given key or null if there is no associated data.

remove

public Map<String,String> remove(String key)

Description copied from interface: SingleUseObjectProvider

This method returns data just if removal was successful. Implementation should guarantee that "remove" is single-use. So if 2 threads (even on different cluster nodes or on different cross-dc nodes) calls "remove(123)" concurrently, then just one of them is allowed to succeed and return data back. It can't happen that both will succeed.

Specified by:

remove in interface SingleUseObjectProvider

Returns:

context data associated to the key. It returns null if there are no context data available.

replace

public boolean replace(String key,
                       Map<String,String> notes)

Description copied from interface: SingleUseObjectProvider

Replaces data associated with the given key in the store if the store contains the key.

Specified by:

replace in interface SingleUseObjectProvider

Parameters:

key - String

notes - Map New data to be stored

Returns:

true if the store contains the key and data was replaced, otherwise false.

putIfAbsent

public boolean putIfAbsent(String key,
                           long lifespanInSeconds)

Description copied from interface: SingleUseObjectProvider

Will try to put the key into the cache. It will succeed just if key is not already there.

Specified by:

putIfAbsent in interface SingleUseObjectProvider

lifespanInSeconds - Minimum lifespan for which successfully added key will be kept in the cache.

Returns:

true if the key was successfully put into the cache. This means that same key wasn't in the cache before

contains

public boolean contains(String key)

Description copied from interface: SingleUseObjectProvider

Checks if there is a record in the store for the given key.

Specified by:

contains in interface SingleUseObjectProvider

Parameters:

key - String

Returns:

true if the record is present in the store, false otherwise.

close

public void close()

Specified by:

close in interface Provider
