WARNING
The policy makes no change in the database, however it logs a message in case missing a table, index, or column in the connected database - unlike option DO_NOTHING which make no log.

Method Detail

values

public static Orm2ddlPolicy[] values()

for (Orm2ddlPolicy c : Orm2ddlPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared
