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.

AUTO_CLEANUP_DELAY

public static final 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

public RepositoryCacheConfig()

Create a default configuration.

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.
