lithium\data\collection\RecordSet::_mapRecord()

protected method

Converts a PDO Result array to a nested Record object.

  1. Builds an associative array with data from the row, with joined row data nested under the relationships name. Joined row data is added and new results consumed from the result cursor under the relationships name until the value of the main primary key changes.

  2. The built array is then hydrated and returned.

Note: Joined records must appear sequentially, when non-sequential records are detected an exception is thrown.

Parameters

  • array $row

    2 dimensional PDO Result array

Returns

object

Returns a Record object
