Examples with CascadingFetchProfile org.hibernate.loader.ast.spi.CascadingFetchProfile used on opensource projects

Example 1 with CascadingFetchProfile

use of org.hibernate.loader.ast.spi.CascadingFetchProfile in project hibernate-orm by hibernate.

the class SingleIdEntityLoaderStandardImpl method resolveLoadPlan.

@Internal
public SingleIdLoadPlan<T> resolveLoadPlan(LockOptions lockOptions, LoadQueryInfluencers loadQueryInfluencers, SessionFactoryImplementor sessionFactory) {

        // 
        // This case is special because the filters need to be applied in order to
        // properly restrict the SQL/JDBC results.  For this reason it has higher
        // precedence than even "internal" fetch profiles.
        nonReusablePlansGenerated.incrementAndGet();
        return createLoadPlan(lockOptions, loadQueryInfluencers, sessionFactory);
    }
