Class OneWayDatabaseVersionFeature

java.lang.Object

com.atlassian.jira.config.feature.OneWayDatabaseVersionFeature

public class OneWayDatabaseVersionFeature
extends Object

Utility which can be used to enable a feature based on the database version provided by currentDatabaseVersionProvider. The meaning of database version is the same as the one defined by: BuildUtilsInfo.getDatabaseBuildNumber() This utility assumes once a feature is enabled this state is permanent and will not call currentDatabaseVersionProvider anymore. The reason for this is to be able to enable a feature based on database version and make the isFeatureEnabled() call cheap so it can be used to enable low level (frequent) features. The feature can be disabled by the provided system property disableFeaturePropertyName - check done only at creation time. If the feature was disabled in the lifetime of this object it will call onFeatureEnabled in the isFeatureEnabled() caller thread (i.e. onFeatureEnabled the first time isFeatureEnabled() returns true).
