$this->_instance = $a;
}
public function getTitleAndAuthor() {
$retval = array(
'title' => $this->_instance->getTitle(),
'author' => $this->_instance->getAuthor()
);
return $retval;

Adaptor pattern helps a class to use some interfaces which are not usable by that class without the adapter class.

Singleton pattern has a private and static constructor.so that there will only one instance of a class.

Abstract factory pattern has some abstract class that are override by other classes.

Decorator pattern adds additional features to an object dynamically.
