Method Detail

setDatabaseConfiguration

public void setDatabaseConfiguration(DatabaseConfig databaseConfig)

Description copied from interface: DatabaseConfigurationManager

Persists the given config as JIRA's database configuration. This must only be done once.

Specified by:

setDatabaseConfiguration in interface DatabaseConfigurationManager

Parameters:

databaseConfig - the config to use for JIRA's database connection.

createDbConfigFromEntityDefinition

public void createDbConfigFromEntityDefinition()

Description copied from interface: DatabaseConfigurationManager

Creates a new dbconfig.xml using the values in entityengine.xml if there are any Allows for upgrade from pre 5.0 instances

Specified by:

createDbConfigFromEntityDefinition in interface DatabaseConfigurationManager

getDatabaseConfiguration

public DatabaseConfig getDatabaseConfiguration()

Description copied from interface: DatabaseConfigurationManager

Gets the current database configuration.

Specified by:

getDatabaseConfiguration in interface DatabaseConfigurationManager

Returns:

the config if configured.

doNowOrWhenDatabaseActivated

public void doNowOrWhenDatabaseActivated(Runnable runnable,
                                         String desc)

Description copied from interface: DatabaseConfigurationManager

Requests that work that needs to read from and write to the database be done. If the database is already active, the runnable will be run now in the calling thread. If not, it will be enqueued until the database configuration is provided and the database is activated via DatabaseConfigurationManager.activateDatabase(). Then it will be done in the thread that calls DatabaseConfigurationManager.activateDatabase().

Callers can be sure that the database schema will already be updated to fit the model when the given runnable is run.

Specified by:

doNowOrWhenDatabaseActivated in interface DatabaseConfigurationManager

Parameters:

runnable - The work that must be done if or when the database is activated.

desc - A description (for logging purposes) of the work.

doNowOrWhenDatabaseConfigured

public void doNowOrWhenDatabaseConfigured(Runnable runnable,
                                          String desc)

Description copied from interface: DatabaseConfigurationManager

Requests that work dependent on the database configuration be done. If the database is already configured, the runnable will be run now in the calling thread. If not, it will be enqueued until the database configuration is provided but before the database is actually activated via DatabaseConfigurationManager.activateDatabase(). Then it will be done in the thread that calls DatabaseConfigurationManager.activateDatabase().

The puropse of this method is to execute tasks that want to check or read the database configuration before the schema is modified to fit the current model.

Specified by:

doNowOrWhenDatabaseConfigured in interface DatabaseConfigurationManager

Parameters:

runnable - The work that must be done if or when the database is configured.

desc - A description (for logging purposes) of the work.

isDatabaseSetup

public boolean isDatabaseSetup()

Description copied from interface: DatabaseConfigurationManager

Returns true only if the database configuration is available.

Specified by:

isDatabaseSetup in interface DatabaseConfigurationManager

Returns:

whether the database is set up.

activateDatabase

public void activateDatabase()

Description copied from interface: DatabaseConfigurationManager

Initialises the first connection to the database and causes each enqueued runnable that registered with DatabaseConfigurationManager.doNowOrWhenDatabaseActivated(Runnable, String) to be run. Should only be run once per application boot.

Specified by:

activateDatabase in interface DatabaseConfigurationManager

activateDatabaseWithoutRunningPostDbSetupRunnables

public void activateDatabaseWithoutRunningPostDbSetupRunnables()

Specified by:

activateDatabaseWithoutRunningPostDbSetupRunnables in interface DatabaseConfigurationManager

runPostDbSetupRunnables

public void runPostDbSetupRunnables()

Specified by:

runPostDbSetupRunnables in interface DatabaseConfigurationManager

getInternalDatabaseConfiguration

public DatabaseConfig getInternalDatabaseConfiguration()

Description copied from interface: DatabaseConfigurationManager

Provides the DatabaseConfig that represents the embedded JIRA database. This does not imply that this config is current or that there is any current configuration for the JIRA database.

Specified by:

getInternalDatabaseConfiguration in interface DatabaseConfigurationManager

Returns:

the embedded database config.
