Class ObjectGraphOrigin

java.lang.Object

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 autoTune can tune each one separately).
