hibernate - Storing and retrieving copmosit objects in Java -


i have more 2 classes have approximately 7 same fields , following in java part:

public abstract class ibase {    private string commonfield1;    private string commonfield2;    private string commonfield3;    private emytype type; // type of object: my_type_1 or my_type_2    // ...     // + constructor , getters/setters }  public class baseimpl1 extends ibase {    private int base1specific1;    private int base1specific2;    // ...     // + constructor , getters/setters }  public class baseimpl2 extends ibase {    private int base2specific;    private string base2specific2;     // ...     // + constructor , getters/setters }

i have 2 questions:

  1. what best way reflect 2 object within database?
  2. how should retrieve them via hibernate?

using morphia, you'd mark interface @entity(somecollectionname). when you're querying types, have datastore.createquery(baseimpl1.class).filter("classname = ", baseimpl1.class.getname()) retrieve particular subclass.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
