Class: xmldb_table - X-Ref
| __construct($name) X-Ref |
| Creates one new xmldb_table param: string $name |
| addField($field, $after=null) X-Ref |
| Add one field to the table, allowing to specify the desired order If it's not specified, then the field is added at the end param: xmldb_field $field param: xmldb_object $after return: xmldb_field |
| addKey($key, $after=null) X-Ref |
| Add one key to the table, allowing to specify the desired order If it's not specified, then the key is added at the end param: xmldb_key $key param: xmldb_object $after |
| addIndex($index, $after=null) X-Ref |
| Add one index to the table, allowing to specify the desired order If it's not specified, then the index is added at the end param: xmldb_index $index param: xmldb_object $after |
| getFields() X-Ref |
| This function will return the array of fields in the table return: xmldb_field[] |
| getKeys() X-Ref |
| This function will return the array of keys in the table return: xmldb_key[] |
| getIndexes() X-Ref |
| This function will return the array of indexes in the table return: xmldb_index[] |
| getField($fieldname) X-Ref |
| Returns one xmldb_field param: string $fieldname return: xmldb_field|null |
| findFieldInArray($fieldname) X-Ref |
| Returns the position of one field in the array. param: string $fieldname return: int|null index of the field, or null if not found. |
| orderFields() X-Ref |
| This function will reorder the array of fields return: bool whether the reordering succeeded. |
| getKey($keyname) X-Ref |
| Returns one xmldb_key param: string $keyname return: xmldb_key|null |
| findKeyInArray($keyname) X-Ref |
| Returns the position of one key in the array. param: string $keyname return: int|null index of the key, or null if not found. |
| orderKeys() X-Ref |
| This function will reorder the array of keys return: bool whether the reordering succeeded. |
| getIndex($indexname) X-Ref |
| Returns one xmldb_index param: string $indexname return: xmldb_index|null |
| findIndexInArray($indexname) X-Ref |
| Returns the position of one index in the array. param: string $indexname return: int|null index of the index, or null if not found. |
| orderIndexes() X-Ref |
| This function will reorder the array of indexes return: bool whether the reordering succeeded. |
| setFields($fields) X-Ref |
| This function will set the array of fields in the table param: xmldb_field[] $fields |
| setKeys($keys) X-Ref |
| This function will set the array of keys in the table param: xmldb_key[] $keys |
| setIndexes($indexes) X-Ref |
| This function will set the array of indexes in the table param: xmldb_index[] $indexes |
| deleteField($fieldname) X-Ref |
| Delete one field from the table param: string $fieldname |

| Delete one index from the table param: string $indexname |
| arr2xmldb_table($xmlarr) X-Ref |
| Load data from XML to the table param: array $xmlarr return: bool success |
| calculateHash($recursive = false) X-Ref |
| This function calculate and set the hash of one xmldb_table param: bool $recursive |
| validateDefinition(xmldb_table $xmldb_table=null) X-Ref |
| Validates the table restrictions (does not validate child elements). The error message should not be localised because it is intended for developers, end users and admins should never see these problems! param: xmldb_table $xmldb_table optional when object is table return: string null if ok, error message if problem found |
