   * Where the query is retrieved from a cached recordset.
+===== Order Of Instantiation =====
+  - A Connection to the database is held in an ADOConnection object
+  - A Query is issued and depending on the type of query, the result is held either:
+     - ADORecordset_<driver> if the query is a select and returns 1 or more records
+     - ADOrecordset_empty if the query is not a select
+     - ADOrecordset_array_<driver> if the resultset is returned from the cache or no recordcount can be obtained.
 ===== Problems =====
-When the class is invoked, it replaces the driver recordset completely. This means that any class methods in the class are destroyed. The  class extension path is from ADOrecordset_array to the driver specific class. The driver
+The ADOrecordset_<driver> class is the repository of all of the driver specific recordset methods, for example ``metaColumns()''. If the query response is held in an object other than this, these methods are unavailable to the class. This is because the ADORecordset_array_<driver> class extenss ADORecordset_array, rather than ADORecordset_driver.
