Public Member Methods | |
| constructor (string n, bool u, hash c) | |
| creates the object from the name, a unique flag, and a hash of column information | |
| bool | equal (AbstractIndex ix) |
| returns True if the argument is equal to the current index, False if not | |
| bool | equalExceptName (AbstractIndex ix) |
| returns True if the argument is equal to the current index with the exception of the name, False if not | |
| abstract bool | equalImpl (AbstractIndex ix) |
| returns True if the argument is equal to the current index, False if not | |
| *list< AbstractColumnConstraint > | getAllSupportingConstraints () |
| returns all supporting constraints, if any | |
| abstract string | getCreateSql (string table_name, *hash< auto > opt) |
| returns a string that can be used to create the index in the database | |
| string | getDropSql (string table_name) |
| returns a string that can be used to drop the index from the database | |
| *AbstractForeignConstraint | getForeignConstraint () |
| returns the supporting constraint, if any | |
| string | getName () |
| returns the index name | |
| list< auto > | getRecreateSql (AbstractDatasource ds, string table_name, *hash< auto > opt) |
| returns a list of strings to drop and recreate the current index; if there are dependent constraints, the list contains commands to disable the constraints before dropping the index and also contains commands to re-enable the contraints after re-creating the index | |
| abstract string | getRenameSql (string table_name, string new_name) |
| returns a string that can be used to rename the index in the database | |
| *AbstractColumnSupportingConstraint | getSupportingConstraint () |
| returns the supporting constraint, if any | |
| bool | hasColumn (string cname) |
| returns True if the constraint references the named column | |
| setForeignConstraint () | |
| clears the supporting constraint | |
| setSupportingConstraint () | |
| clears the supporting constraint | |
| setSupportingConstraint (AbstractColumnSupportingConstraint c) | |
| tags the index with a column supporting constraint (unique or fk constraint, etc) that the index supports | |
| setSupportingConstraint (AbstractForeignConstraint c) | |
| tags the index with a column supporting constraint (unique or fk constraint, etc) that the index supports | |
Public Attributes | |
| Columns | columns |
| an object of class Columns representing the columns in the index | |
| string | name |
| the name of the index | |
| bool | unique |
| True if the index is a unique index, False if not | |
Private Attributes | |
| *AbstractColumnSupportingConstraint | constraint |
| the AbstractColumnSupportingConstraint that this index supports, if any | |
| *AbstractForeignConstraint | foreign_constraint |
| Any foreign constraint that this index supports. | |
