Detailed Description

A recursive array iterator.

Author:

Marcus Boerger

Version:

1.0

Since:

PHP 5.1

Passes the RecursiveIterator interface to the inner Iterator and provides the same functionality as FilterIterator. This allows you to skip parents and all their childs before loading them all. You need to care about function getChildren() because it may not always suit your needs. The builtin behavior uses reflection to return a new instance of the exact same class it is called from. That is you extend RecursiveFilterIterator and getChildren() will create instance of that class. The problem is that doing this does not transport any state or control information of your accept() implementation to the new instance. To overcome this problem you might need to overwrite getChildren(), call this implementation and pass the control vaules manually.

(

$

value

)

[inherited]

Parameters:

$value

is appended as last element

Warning:

this method cannot be called when the ArrayIterator refers to an object.

Definition at line 804 of file spl.php.

{}

ArrayIterator::asort

(

)

[inherited]

Sort the entries by values.

Definition at line 759 of file spl.php.

{}

ArrayIterator::count

(

)

[inherited]

Returns:

the number of elements in the array or the number of public properties in the object.

Implements Countable.

Definition at line 820 of file spl.php.

{}

ArrayIterator::current

(

ArrayIterator::getArrayCopy

(

)

[inherited]

an iterator for the current elements children

Note:

the returned iterator will be of the same class as $this
