Example 1 with LazyValue

use of org.hibernate.internal.util.LazyValue in project hibernate-orm by hibernate.

the class AbstractEntityPersister method prepareMappingModel.

private void prepareMappingModel(MappingModelCreationProcess creationProcess, PersistentClass bootEntityDescriptor) {
    final EntityInstantiator instantiator = getRepresentationStrategy().getInstantiator();
    final Supplier<?> templateInstanceCreator;

        templateInstanceCreator = null;
    } else {
        final LazyValue<?> templateCreator = new LazyValue<>(() -> instantiator.instantiate(creationProcess.getCreationContext().getSessionFactory()));
        templateInstanceCreator = templateCreator::getValue;
    }
    identifierMapping = creationProcess.processSubPart(EntityIdentifierMapping.ROLE_LOCAL_NAME, (role, process) -> generateIdentifierMapping(templateInstanceCreator, bootEntityDescriptor, process));
    versionMapping = generateVersionMapping(templateInstanceCreator, bootEntityDescriptor, creationProcess);
    if (rowIdName == null) {
        rowIdMapping = null;
    } else {
        rowIdMapping = creationProcess.processSubPart(rowIdName, (role, process) -> new EntityRowIdMappingImpl(rowIdName, this.getTableName(), this));
