A result-set from a MySQL database (using MySQLiConnector)
Properties
| protected | array | $currentRecord | The current record in the interator. |
from SS_Query |
| protected | int | $rowNum | The number of the current row in the interator. |
from SS_Query |
| protected | bool | $queryHasBegun | Flag to keep track of whether iteration has begun, to prevent unnecessary seeks |

Methods
Return an array containing all the values from a specific column. If no column is set, then the first will be returned
Return an array containing all values in the leftmost column, where the keys are the same as the values.
Iterator function implementation. Rewind the iterator to the first item and return it.
Iterator function implementation. Return the current item of the iterator.
Iterator function implementation. Return the first item of this iterator.
Iterator function implementation. Return the row number of the current item.
Iterator function implementation. Return the next record in the iterator.
Iterator function implementation. Check if the iterator is pointing to a valid item.
Hook the result-set given into a Query class, suitable for use by SilverStripe.

Makes use of nextRecord(), takes care of the plumbing.
bool
valid()
Iterator function implementation. Check if the iterator is pointing to a valid item.
array
nextRecord()
Return the next record in the query result.
