Abstract class Phalcon\Mvc\Model\Resultset
implements Phalcon\Mvc\Model\ResultsetInterface, Iterator, Traversable, SeekableIterator, Countable, ArrayAccess, Serializable
This component allows to Phalcon\Mvc\Model returns large resulsets with the minimum memory consumption Resulsets can be traversed using a standard foreach or a while statement. If a resultset is serialized it will dump all the rows into a big array. Then unserialize will retrieve the rows as they were before serializing.
<?php
//Using a standard foreach
$robots = Robots::find(array("type='virtual'", "order" => "name"));
foreach ($robots as robot) {
echo robot->name, "\n";
}
//Using a while
$robots = Robots::find(array("type='virtual'", "order" => "name"));
$robots->rewind();
while ($robots->valid()) {
$robot = $robots->current();
echo $robot->name, "\n";
$robots->next();
}

Methods
public next ()
Moves cursor to next row in the resultset
public int key ()
Gets pointer number of active row in the resultset
final public rewind ()
Rewinds resultset to its beginning
final public seek (unknown $position)
Changes internal pointer to a specific position in the resultset
final public int count ()
Counts how many rows are in the resultset
public boolean offsetExists (unknown $index)
Checks whether offset exists in the resultset
public Phalcon\Mvc\ModelInterface offsetGet (unknown $index)
Gets row in a specific position of the resultset
public offsetSet (unknown $index, unknown $value)
Resulsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface
public offsetUnset (unknown $offset)
Resulsets cannot be changed. It has only been implemented to meet the definition of the ArrayAccess interface
public int getType ()
Returns the internal type of data retrieval that the resultset is using
public Phalcon\Mvc\ModelInterface |boolean getFirst ()
Get first row in the resultset
public Phalcon\Mvc\ModelInterface | boolean getLast ()
Get last row in the resultset
public Phalcon\Mvc\Model\Resultset setIsFresh (unknown $isFresh)
Set if the resultset is fresh or an old one cached
public boolean isFresh ()
Tell if the resultset if fresh or an old one cached
public Phalcon\Mvc\Model\Resultset setHydrateMode (unknown $hydrateMode)
Sets the hydration mode in the resultset
public int getHydrateMode ()
Returns the current hydration mode
public Phalcon\Cache\BackendInterface getCache ()
Returns the associated cache for the resultset
final public Phalcon\Mvc\ModelInterface current ()
Returns current row in the resultset
public Phalcon\Mvc\Model\MessageInterface [] getMessages ()
Returns the error messages produced by a batch operation
public boolean update (unknown $data, [unknown $conditionCallback])
Updates every record in the resultset
public boolean delete ([unknown $conditionCallback])
Deletes every record in the resultset
public Phalcon\Mvc\Model [] filter (unknown $filter)
Filters a resultset returning only those the developer requires
<?php
$filtered = $robots->filter(function($robot){
if ($robot->id < 3) {
return $robot;
}
