        Advanced: Delete(deep)


        When an object is identified as “Parent", POG generates the object with a slightly different Delete CRUD method. The modified Delete method is known as Delete($DEEP). The Delete($DEEP) method extends the functionality of the traditional DELETE method by allowing you to recursively delete all child objects associated with the parent object. By default, parent objects are NOT deleted deep if the $deep parameter is not specified.

        When an object is identified as "Sibling", POG generates the object with a slightly different Delete CRUD method. The modified Delete method is known as Delete($DEEP,$ACROSS). The Delete($DEEP,$ACROSS) method extends the functionality of the traditional DELETE method by allowing you to choose whether you want to delete down or across the 'family tree'. If across is set to true and deep is set to false, then all siblings of the current object will be deleted *recursively*. If the sibling object has any children itself, these child objects will not be deleted.

        PHP:
        //To Delete an object ‘deep’, simply do the following:
        $book = new Book( ) ; //create a child object
        $book -> title = " State of Fear" ;
        $author = new Author ( ) ; //create a parent object
        $author -> name = ‘Michael Critchton’ ;
        $author -> AddBook($book) ;
        $author -> Delete ( t rue) ; //deletes both Author and Book
        //Note: Delete(true) different from Delete():

        //To Delete an object ‘shallow’, simply do the following:
        $book = new Book( ) ; //create a child object
        $book -> t i t le = " State of Fear " ;
        $author = new Author( ) ; //create a parent object
        $author -> name = ‘Michael Critchton’ ;
        $author -> AddBook($book) ;
        $author -> Delete (false) ; //Deletes only Author object
        //Note: Delete(false) is the same as Delete()
