Class ObjectGraphOrigin

java.lang.Object
  extended by com.avaje.ebean.bean.ObjectGraphOrigin
All Implemented Interfaces:
Serializable

public final class ObjectGraphOrigin
extends Object

    
implements Serializable

    

Represents a "origin" of an ORM object graph. This combines the call stack and query plan hash.

The call stack is included so that the query can have different tuned fetches for each unique call stack. For example, a query to fetch a customer could be called by three different methods and each can be treated as a separate origin point (and autoFetch can tune each one separately).
