Minutes: JDO TCK Conference Call Friday July 8, 9 AM Pacific Daylight Time (PDT)

[Craig Russell]

Attendees: Michael Bouschen, Tilmann Zäschke, Craig Russell

NOTE: We have a new video conference. Please disregard the previous one.

Next meeting will take place on Thursday June 15 at 9:00 PDT.

Agenda:

1. New patch on JDO-751 "Support for Java8 Optional" 
https://issues.apache.org/jira/browse/JDO-751

Discussion continues in the JIRA

Persistent Object Model 6.4.3
java.lang.Optional types
JDO implementations must support fields of type Optional where T is an 
Immutable Object Class types, java.util.Date, Enum types, or 
Persistence-capable Class types. They may be mapped nullable datastore types or 
to Optional types at the option of the JDO implementation.

When instantiating an instance from the datastore, the JDO implementation would 
get the value v from the datastore and assign the field f = 
Optional.ofNullable(v). When storing the field in the datastore, the 
persistence implementation would store the result of v = 
f.isPresent()?f.get():null.

Navigation in JDOQL via optional.optional seems to be an issue. It looks 
similar to navigating the Company model, e.g. WHERE this.manager.manager.name 
== ‘Michael’. AI: Michael try some experiments with queries and multiple 
navigations.
