RE:como la explicacion de esta clase
como la explicacion del algunos métodos de esta clase, si se puede que me digas de que tipo son las variables y como se usan en dicha funcion
class DataRecord implements Iterator, ArrayAccess
{
protected $m_var = array();
protected $m_var_old = array();
protected $m_BizObj = null;
public function __construct($recArray, $bizObj)
{
if ($recArray != null && is_array($recArray))
{
$this->m_var = $recArray;
$this->m_var_old = $recArray;
}
$this->m_BizObj = $bizObj;
}
// Iterator methods
public function get($key) { return isset($this->m_var[$key]) ? $this->m_var[$key] : null; }
public function set($key, $val) { $this->m_var[$key] = $val; }
public function rewind() { reset($this->m_var); }
public function current() { return current($this->m_var); }
public function key() { return key($this->m_var); }
public function next() { return next($this->m_var); }
public function valid() { return $this->current() !== false; }
// ArrayAccess methods
public function offsetExists($key) { return isset($this->m_var[$key]); }
public function offsetGet($key) { return $this->get($key); }
public function offsetSet($key, $val) { $this->set($key, $val); }
public function offsetUnset($key) { unset($this->m_var[$key]); }
public function __get($field)
{
return $this->get($field);
}
public function __set($field, $value)
{
$this->set($field, $value);
}
// save record - call BizDataObj UpdateRecord method
public function Save()
{
if (count($this->m_var_old) > 0)
$ok = $this->m_BizObj->UpdateRecord($this->m_var, $this->m_var_old);
else
$ok = $this->m_BizObj->InsertRecord($this->m_var);
return $ok;
}
// delete record - call BizDataObj DeleteRecord method
public function Delete()
{
return $this->m_BizObj->DeleteRecord($this->m_var);
}
// return record in array
public function toArray()
{
return $this->m_var;
}
// get reference object with given object name
public function GetRefObject($objName)

}
