    • Field Summary

      Fields 
      Modifier and Type Field Description
      static long AUTO_CLEANUP_DELAY
      Set cleanupDelayMillis to this value in order to auto-set it to minimum of 1/10 of expireAfterMillis and 10 minutes
      static long NO_CLEANUP
      Set cleanupDelayMillis to this value in order to switch off time-based cache eviction.

      Constructor Description
      RepositoryCacheConfig()
      Create a default configuration.

    • Field Detail

      • NO_CLEANUP

        public static final long NO_CLEANUP
        Set cleanupDelayMillis to this value in order to switch off time-based cache eviction. Expired cache entries will only be evicted when RepositoryCache.clearExpired or RepositoryCache.clear are called.

    • Method Detail

      • getExpireAfter

        public long getExpireAfter()
        Get the time an unused repository should be expired and be evicted from the RepositoryCache in milliseconds.
        Returns:
        the time an unused repository should be expired and be evicted from the RepositoryCache in milliseconds. Default is 1 hour.

      • setExpireAfter

        public void setExpireAfter​(long expireAfterMillis)
        Set the time an unused repository should be expired and be evicted from the RepositoryCache in milliseconds.
        Parameters:
        expireAfterMillis - the time an unused repository should be expired and be evicted from the RepositoryCache in milliseconds.

      • getCleanupDelay

        public long getCleanupDelay()
        Get the delay between the periodic cleanup of expired repository in milliseconds.
        Returns:
        the delay between the periodic cleanup of expired repository in milliseconds. Default is minimum of 1/10 of expireAfterMillis and 10 minutes

      • setCleanupDelay

        public void setCleanupDelay​(long cleanupDelayMillis)
        Set the delay between the periodic cleanup of expired repository in milliseconds.
        Parameters:
        cleanupDelayMillis - the delay between the periodic cleanup of expired repository in milliseconds. Set it to AUTO_CLEANUP_DELAY to automatically derive cleanup delay from expireAfterMillis.

        Set it to NO_CLEANUP in order to switch off cache expiration.

        If cache expiration is switched off the JVM still can evict cache entries when the JVM is running low on available heap memory.

      • fromConfig

        public RepositoryCacheConfig fromConfig​(Config config)
        Update properties by setting fields from the configuration.

        If a property is not defined in the configuration, then it is left unmodified.

        Parameters:
        config - configuration to read properties from.
        Returns:
        this.

      • install

        public void install()
        Install this configuration as the live settings.

        The new configuration is applied immediately.
