Constructor & Destructor Documentation

__construct

(

array

$config

)

Constructor.

Parameters

array

$config

Member Function Documentation

__sleep

(

)

Store data, class names, and state in serialized object.

Returns

array

__wakeup

(

)

Setup to do on wakeup.

A de-serialized Rowset should not be assumed to have access to a live database connection, so set _connected = false.

Returns

void

_loadAndReturnRow (   $position )

protected

count

(

)

Returns the number of elements in the collection.

Implements Countable::count()

Returns

int

current

(

)

Return the current element.

Similar to the current() function for arrays in PHP Required by interface Iterator.

Returns

Zend_Db_Table_Row_Abstract current element from the collection

getRow	(		$position,
			$seek = false
	)

Returns a Zend_Db_Table_Row from a known position into the Iterator.

Parameters

int	$position	the position of the row expected
bool	$seek	wether or not seek the iterator to that position after

Returns

Zend_Db_Table_Row

Exceptions

Zend_Db_Table_Rowset_Exception

getTable

(

)

Returns the table object, or null if this is disconnected rowset.

Returns

Zend_Db_Table_Abstract

getTableClass

(

)

Query the class name of the Table object for which this Rowset was created.

Returns

string

init

(

)

Initialize object.

Called from __construct() as final step of object instantiation.

Returns

void

isConnected

(

)

Return the connected state of the rowset.

Returns

boolean

key

(

)

Return the identifying key of the current element.

Similar to the key() function for arrays in PHP. Required by interface Iterator.

Returns

int

next

(

)

Move forward to next element.

Similar to the next() function for arrays in PHP. Required by interface Iterator.

Returns

void

offsetExists

(

$offset

)

Check if an offset exists Required by the ArrayAccess implementation.

Parameters

string

$offset

Returns

boolean

offsetGet

(

$offset

)

Get the row for the given offset Required by the ArrayAccess implementation.

Parameters

string

$offset

Returns

Zend_Db_Table_Row_Abstract

offsetSet	(		$offset,
			$value
	)

Does nothing Required by the ArrayAccess implementation.

Parameters

string	$offset
mixed	$value

offsetUnset

(

$offset

)

Does nothing Required by the ArrayAccess implementation.

Parameters

string

$offset

rewind

(

)

Rewind the Iterator to the first element.

Similar to the reset() function for arrays in PHP. Required by interface Iterator.

Returns

Zend_Db_Table_Rowset_Abstract Fluent interface.

seek

(

$position

)

Take the Iterator to position $position Required by interface SeekableIterator.

Parameters

int

$position

the position to seek to

Returns

Zend_Db_Table_Rowset_Abstract

Exceptions

Zend_Db_Table_Rowset_Exception

setTable

(

Zend_Db_Table_Abstract

$table

)

Set the table object, to re-establish a live connection to the database for a Rowset that has been de-serialized.

Parameters

Zend_Db_Table_Abstract

$table

Returns

boolean

Exceptions

Zend_Db_Table_Row_Exception

toArray

(

)

Returns all data as an array.

Updates the $_data property with current row object values.

Returns

array

valid

(

)

Check if there is a current element after calls to rewind() or next().

Used to check if we've iterated to the end of the collection. Required by interface Iterator.

Returns

bool False if there's nothing more to iterate over
