Examples of com.avaje.ebean.bean.ObjectGraphOrigin

com.avaje.ebean.bean.ObjectGraphOrigin
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).

  public ObjectGraphNode setOrigin(CallStack callStack) {


    // create a 'origin' which links this query to the profiling information
    ObjectGraphOrigin o = new ObjectGraphOrigin(calculateOriginQueryHash(), callStack, beanType.getName());
    parentNode = new ObjectGraphNode(o, null);
    return parentNode;
