| 26 | * Utility class to ease the migration process. |
| 27 | * |
| 28 | * Every migration must go in its own method |
| 29 | * The naming convention is migrateUpTo_XXX where XXX is the number of the version, |
| 30 | * format is numbers only. |
| 31 | * Example: migration for version upto 1.4 must be in migrateUpTo_14 method |
| 32 | * |
| 33 | * The numbers in the names of the methods must have exact numbers count as in the selected |
| 34 | * version in use, even if there are silent numbers for some of the major versions as 1, 2, 3 etc. (the .0.0 is skipped / silent) |
| 35 | * Example: |
| 36 | * - if X.X.X is selected for version number, then for version 1.1 method must have "...migrateUpTo_110..." in its name |
| 37 | * - if X.X is selected for version number, then for version 1, method must have "...migrateUpTo_10..." in its name |
| 38 | * |
| 39 | * Note: you can add prefix to the migration method, if that is necessary, but "migrateUpTo_" is a must - |
| 40 | * the name must contain that @see getAllMigrationMethodsAsNumbers of that class. |
| 41 | * For version extraction the number following the last '_' will be used |
| 42 | * TODO: the mandatory part of the method name can be a setting in the class, but is that a good idea? |
| 43 | * |
| 44 | * Note: order of the methods is not preserved - version numbers will be used for ordering |
