Why is ArrayIterator subclass's constructor never called?

I'm baffled why a subclass to ArrayIterator is never getting its __construct method called. Consider this example:,The iteratorClass variable from the constructor (or set through setIteratorClass) would suggest that this class gets instantiated whenever we retrieve the iterator from the ArrayObject. But it does not do regular "instantiation", as this is not possible.,It will just initialize the iterator (allocate memory etc), but not call the constructor. It makes sense to not call the constructor, as the constructor of an ArrayIterator takes two arguments ($array and $flags), and your class might have changed its signature, maybe even adding more (mandatory values)., Constructors on built-in objects are a bit funky - note for instance that SimpleXMLElement declares its constructor to be final, so that subclasses have to go through the right factory procedure. That's not true of ArrayIterator, though, so maybe this is just a bug. – IMSoP May 27 '15 at 23:42

Method __construct was called, as usually, on creating new instance:

$it = new FooIterator();

getArray public Object getArray() Gets the array that this iterator is iterating over. Returns:the array this iterator iterates over, or null if the no-arg constructor was used and setArray(Object) has never been called with a valid array. , Using this constructor, the iterator is equivalent to an empty iterator until setArray(Object) is called to establish the array to iterate over., ArrayIterator public ArrayIterator() Constructor for use with setArray. Using this constructor, the iterator is equivalent to an empty iterator until setArray(Object) is called to establish the array to iterate over. , If an array has previously been set (using the single-arg constructor or this method) then that array is discarded in favour of this one. Iteration is restarted at the start of the new array. Although this can be used to reset iteration, the reset() method is a more effective choice.

When you want to iterate over the same array multiple times you need to instantiate ArrayObject and let it create ArrayIterator instances that refer to it either by using foreach or by calling its getIterator() method manually. , This iterator allows to unset and modify values and keys while iterating over Arrays and Objects. ,ArrayIterator::valid — Check whether array contains more entries,ArrayIterator::natcasesort — Sort entries naturally, case insensitive

Inheritance or overloading is not allowed in static constructors.,A specific class can possess only a single static constructor.,A static constructor does not allow the use of “this” keyword to access an instance.,It cannot be called directly since it is always invoked automatically.

Syntax:

public class <Class_Name> {
private <datatype> <variable>;
public static <Constructor_Name> () {}
}

public class <Class_Name> {
private <datatype> <variable>;
public static <Constructor_Name> () {}
}

In the meanwhile we have graduated from the Apache Incubator, have set up a regular release cycle and have started publishing maven artifacts in Maven Central,In case you still need to access Oracle binaries or artifacts, some individuals have created a backup of those that you may want to use. Here is a list:,During the next five years Oracle has also been supporting the NetBeans Project with some server infrastructure (and a great team!). This has been of course of great help, and has allowed us to move forward. We want to thank Oracle for all this help.,In 2016 Oracle donated the source code of NetBeans to the Apache Software Foundation (see Our History for details).
