---|
24 | * ColumnMap is used to model a column of a table in a database. |
---|
25 | * |
---|
26 | * GENERAL NOTE |
---|
27 | * ------------ |
---|
28 | * The propel.map classes are abstract building-block classes for modeling |
---|
29 | * the database at runtime. These classes are similar (a lite version) to the |
---|
30 | * propel.engine.database.model classes, which are build-time modeling classes. |
---|
31 | * These classes in themselves do not do any database metadata lookups, but instead |
---|
32 | * are used by the MapBuilder classes that were generated for your datamodel. The |
---|
33 | * MapBuilder that was created for your datamodel build a representation of your |
---|
34 | * database by creating instances of the DatabaseMap, TableMap, ColumnMap, etc. |
---|
35 | * classes. See propel/templates/om/php5/MapBuilder.tpl and the classes generated |
---|
36 | * by that template for your datamodel to further understand how these are put |
---|
37 | * together. |
