Fatal error: Cannot override final method BusinessLayer::Find()

[Darghon]

Hi all,

 

I seem to be encountering the title error every time I initiate an object that extends my BusinessLayer object.

The error means that I attempt to re-declare a final method, and that's not allowed, but I'm not redeclaring anything.

Are there any potential other reasons that this error is triggered?

 

The following 3 objects are the objects that I construct.

 

User:

<?php
/**
 * This class is the user control for User.
 * Any custom actions to this database object need to be specified here.
 * 
 * @author Darghon
 */
class User extends baseUser{

}
?>

 

baseUser:

<?php 
class baseUser extends BusinessLayer{

/**
 * Public get function that retrieves the ID
 * @return integer $ID
 */
public function getID(){ return $this->data->ID; }

/**
 * Public set function that sets the ID
 * @param integer $ID
 */
public function setID($val){ $this->data->ID = $val; }

/**
 * Public get function that retrieves the Name
 * @return string $Name
 */
public function getName(){ return $this->data->Name; }

/**
 * Public set function that sets the Name
 * @param string $Name
 */
public function setName($val){ $this->data->Name = $val; }



/** more getters and setters here, but have been cropped **/



/**
 * Public get function that retrieves the Record_Version
 * @return integer $Record_Version
 */
public function getRecordVersion(){ return $this->data->Record_Version; }

/**
 * Public set function that sets the Record_Version
 * @param integer $Record_Version
 */
public function setRecordVersion($val){ $this->data->Record_Version = $val; }

/**
 * Public get function that retrieves the Delflag
 * @return boolean $Delflag
 */
public function getDelflag(){ return $this->data->Delflag; }

/**
 * Public set function that sets the Delflag
 * @param boolean $Delflag
 */
public function setDelflag($val){ $this->data->Delflag = $val; }

/**
 * Magic to string method
 * @return String 
 */
public function __toString(){
	return $this->data->Name;
}

/**
 * Object validator, if this class returns true, the object can is valid and can be saved.
 * @return Boolean 
 */
public function validate(){
	return parent::validate();
}

/**
 * Public Destructor, unset every used valiable
 * @return String 
 */
public function __destroy(){
	foreach($this as $key => $val) unset($this->$key);
	unset($this);
}
}
?>

 

BusinessLayer:

<?php

abstract class BusinessLayer {

/**
 * Dataobject that is embedded within the business object
 * @var DataLayer
 */
protected $data = null;

/**
 * New objects require a new instance of 
 */
public function __construct($data = null) {
	$class = 'D' . get_class($this);
	if (get_class($data) == $class) {
		$this->data = $data;
	} else {
		$this->data = new $class();
	}
}

public function _set($var, $value) {
	$this->$var = $value;
}

public function fromArray($arr) {
	foreach ($arr as $field => $value) {
		$fun = "set" . Tools::strtocamelcase($field, true);
		if ($fun == "setId")
			$fun = "setID";
		if (!method_exists($this, $fun))
			continue;
		if (strpos($fun, "ID") > -1) {
			$this->$fun((int) $value);
		} else {
			$this->$fun($value);
		}
	}
}

public function toArray() {
	$result = array();
	$fields = $this->data->getFields();
	foreach ($fields as $field => $changed) {
		$result[$field] = $this->data->$field;
	}
	return $result;
}


public function validate() {
	return true;
}

/**  MORE CODE CROPPING HERE **/

/**
 * Static function that creates a "Find" static function to each business object, which in turn is basicly a shortkey to get The Findertype, or when an ID is passed, to get the object by that ID
 * @return Finder
 */
final public static function & Find($id = null) {
	$caller = function_exists('get_called_class') ? get_called_class() : Tools::getCaller();
	if ($id !== null) {
		$return = &Database::Find($caller)->byID($id);
	} else {
		$return = &Database::Find($caller);
	}
	return $return;
}

public static function is_a($class_name) {
	return (__CLASS__ == $class_name) ? true : false;
}

}

?>

 

As you can see, the function isn't re-declared, so I have no clue why it triggers the error now...

Using Ubuntu 12.04 and php 5.3

 

Thx for any help
