Method Detail

cleanUp

public void cleanUp()

Description copied from interface: FlagsmithCache

estimatedSize

public long estimatedSize()

Description copied from interface: FlagsmithCache

Returns the approximate number of entries in this cache. The value returned is an estimate; the actual count may differ if there are concurrent insertions or removals, or if some entries are pending removal due to expiration or weak/soft reference collection. In the case of stale entries this inaccuracy can be mitigated by performing a cleanUp() first.

Specified by:

estimatedSize in interface FlagsmithCache

Returns:

the estimated size

stats

public com.github.benmanes.caffeine.cache.stats.CacheStats stats()

Description copied from interface: FlagsmithCache

Returns a current snapshot of this cache's cumulative statistics. All statistics are initialized to zero, and are monotonically increasing over the lifetime of the cache.

Specified by:

stats in interface FlagsmithCache

Returns:

stats object

getIfPresent

public Flags getIfPresent(String key)

Description copied from interface: FlagsmithCache

Returns the value associated with key in this cache, or null if there is no cached value for key. It will not attempt to fetch flags from Flagsmith.

Specified by:

Parameters:

key - a key to retrieve value for

Returns:

flags and traits in cache or null

getEnvFlagsCacheKey

public String getEnvFlagsCacheKey()

Description copied from interface: FlagsmithCache
