gbadner / HHH-10478: OperationContext
Last active Feb 6, 2016
Overview of OperationContext design
View HHH-10478: OperationContext
Note: There are some details that need to be discussed. I will create a separate gist
for those details shortly.
Design Overview
An OperationContext is intended to allow data important to an operation that is currently in progress,
that is needed in different areas of hibernate ORM code base. It allows data to be accessible without
having to pass it along as an argument from method to method to where it is needed.

Different types of Type
View gist:9099683
(11:26:53 AM) sebersole: i almost want to make it build the "domain model" first
(11:27:23 AM) sebersole: and use that to reference class names, attributes, etc
(11:27:34 AM) gbadner: +1
(11:28:03 AM) gbadner: I understand now why you had Type.getClassName() and getClassReference()
(11:29:00 AM) gbadner: it would be really nice if o.h.metamodel.spi.Type encapsulated HibernateTypeDescription
(11:29:15 AM) sebersole: it cant always
(11:29:30 AM) sebersole: especially in the case of composites
(11:29:56 AM) sebersole: think the distinction between Embeddable and Embedded
(11:30:13 AM) sebersole: Type would be the Embeddable
(11:30:28 AM) sebersole: HibernateTypeDescription would be the Embedded

"Integration" failures due to replacing org.hibernate.metamodel
View gist:8648491
org.hibernate.test.cid.CompositeIdWithGeneratorTest fails in master because new metamodel cannot handle an IdentityGenerator w/ more than one column. (was changed to IdentifierGenerator on metamodel branch).
org.hibernate.test.propertyref.basic.BasicPropertiesTest fails on master; not in metamodel branch.
Tests that extend BaseUnitTestCase (and not BaseCoreFunctionalTestCase) that explicitly build Configuration (requires merging changes to testing code from metamodel branch). For now, they throw NotYetImplementedException:
- org.hibernate.test.annotations.access.xml.XmlAccessTest
- org.hibernate.test.annotations.uniqueconstraint.UniqueConstraintValidationTest
- org.hibernate.test.cfg.cache.CacheConfigurationTest
- org.hibernate.test.nationalized.SimpleNationalizedTest
