Examples of com.avaje.ebean.bean.EntityBeanIntercept

com.avaje.ebean.bean.EntityBeanIntercept
This is the object added to every entity bean using byte code enhancement.
This provides the mechanisms to support deferred fetching of reference beans and oldValues generation for concurrency checking.

                // build a single object graph, and another thread has since
                // loaded a matching bean so we will use that instead.
                ref = existingBean;
                
            } else {
                EntityBeanIntercept ebi = ((EntityBean) ref)._ebean_getIntercept();
                if (Boolean.TRUE.equals(ctx.isReadOnly())){
                    ebi.setReadOnly(true);
                }
