| 4 | | -/** |
| 5 | | - * Abstract base class for representing objects that are stored in some DB table. |
| 6 | | - * This is basically an ORM-like wrapper around rows in database tables that |
| 7 | | - * aims to be both simple and very flexible. It is centered around an associative |
| 8 | | - * array of fields and various methods to do common interaction with the database. |
| 9 | | - * |
| 10 | | - * These methods must be implemented in deriving classes: |
| 11 | | - * * getDBTable |
| 12 | | - * * getFieldPrefix |
| 13 | | - * * getFieldTypes |
| 14 | | - * |
| 15 | | - * These methods are likely candidates for overriding: |
| 16 | | - * * getDefaults |
| 17 | | - * * remove |
| 18 | | - * * insert |
| 19 | | - * * saveExisting |
| 20 | | - * * loadSummaryFields |
| 21 | | - * * getSummaryFields |
| 22 | | - * |
| 23 | | - * Main instance methods: |
| 24 | | - * * getField(s) |
| 25 | | - * * setField(s) |
| 26 | | - * * save |
| 27 | | - * * remove |
| 28 | | - * |
| 29 | | - * Main static methods: |
| 30 | | - * * select |
| 31 | | - * * update |
| 32 | | - * * delete |
| 33 | | - * * count |
| 34 | | - * * has |
| 35 | | - * * selectRow |
| 36 | | - * * selectFields |
| 37 | | - * * selectFieldsRow |
