Class d_Association

java.lang.Object
  com.orientechnologies.jdo.types.d_Association

All Implemented Interfaces:

java.util.Map.Entry

public class d_Association

extends java.lang.Object

implements java.util.Map.Entry

Express an association key/value. This class is often used in Map collections to contains entries. If the value is a reference (oOID object), then on first access (get() method) the references will be resolved in the real object.

This behaviour avoid the loading of concrete objects in cache, but only real required by application on the first use.
