Methods
-------

public  **__construct** (*array* $columnTypes, [:doc:`Phalcon\\Db\\ResultInterface <Phalcon_Db_ResultInterface>` $result], [:doc:`Phalcon\\Cache\\BackendInterface <Phalcon_Cache_BackendInterface>` $cache])

Phalcon\\Mvc\\Model\\Resultset\\Complex constructor



final public  **current** ()

Returns current row in the resultset



public  **toArray** ()

Returns a complete resultset as an array, if the resultset has a big number of rows it could consume more memory than currently it does.



public  **serialize** ()

Serializing a resultset will dump all related rows into a big array



public  **unserialize** (*mixed* $data)

Unserializing a resultset will allow to only works on the rows present in the saved state



public  **next** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Moves cursor to next row in the resultset



public  **valid** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Check whether internal resource has rows to fetch



public  **key** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Gets pointer number of active row in the resultset

Rewinds resultset to its beginning



final public  **seek** (*mixed* $position) inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Changes internal pointer to a specific position in the resultset Set new position if required and set this->_row



final public  **count** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Counts how many rows are in the resultset



public  **offsetExists** (*mixed* $index) inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Checks whether offset exists in the resultset



public  **offsetGet** (*mixed* $index) inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Gets row in a specific position of the resultset



public  **offsetSet** (*int* $index, :doc:`Phalcon\\Mvc\\ModelInterface <Phalcon_Mvc_ModelInterface>` $value) inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Resultsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface



public  **offsetUnset** (*mixed* $offset) inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Resultsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface



public  **getType** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`

Returns the internal type of data retrieval that the resultset is using



public  **getFirst** () inherited from :doc:`Phalcon\\Mvc\\Model\\Resultset <Phalcon_Mvc_Model_Resultset>`
