Method Detail

fromClassLoader

public static play.api.db.evolutions.EvolutionsReader fromClassLoader()

Create an evolutions reader that reads evolution files from this classes own classloader. Only useful in simple classloading environments, such as when the classloader structure is flat.

fromClassLoader

public static play.api.db.evolutions.EvolutionsReader fromClassLoader(java.lang.ClassLoader classLoader)

Create an evolutions reader that reads evolution files from a classloader.

Parameters:

classLoader - The classloader to read from.

fromClassLoader

public static play.api.db.evolutions.EvolutionsReader fromClassLoader(java.lang.ClassLoader classLoader,
                                                                      java.lang.String prefix)

Create an evolutions reader that reads evolution files from a classloader.

Parameters:

classLoader - The classloader to read from.

prefix - A prefix that gets added to the resource file names, for example, this could be used to namespace evolutions in different environments to work with different databases.

fromMap

public static play.api.db.evolutions.EvolutionsReader fromMap(java.util.Map<java.lang.String,java.util.List<Evolution>> evolutions)

Create an evolutions reader based on a simple map of database names to evolutions.

Parameters:

evolutions - The map of database names to evolutions.

forDefault

public static play.api.db.evolutions.EvolutionsReader forDefault(Evolution... evolutions)

Create an evolutions reader for the default database from a list of evolutions.

Parameters:

evolutions - The list of evolutions.

applyEvolutions

public static void applyEvolutions(Database database,
                                   play.api.db.evolutions.EvolutionsReader reader,
                                   boolean autocommit)

Apply evolutions for the given database.

Parameters:

database - The database to apply the evolutions to.

reader - The reader to read the evolutions.

autocommit - Whether autocommit should be used.

applyEvolutions

public static void applyEvolutions(Database database,
                                   play.api.db.evolutions.EvolutionsReader reader)

Apply evolutions for the given database.

Parameters:

database - The database to apply the evolutions to.

reader - The reader to read the evolutions.

applyEvolutions

public static void applyEvolutions(Database database)

Apply evolutions for the given database.

Parameters:

database - The database to apply the evolutions to.

cleanupEvolutions

public static void cleanupEvolutions(Database database,
                                     boolean autocommit)

Cleanup evolutions for the given database. This will run the down scripts for all the applied evolutions.

Parameters:

database - The database to apply the evolutions to.

autocommit - Whether autocommit should be used.
