-----------------------------------
Summary: Q class specification of candidate() method
Key: JDO-842
URL: https://issues.apache.org/jira/browse/JDO-842
Project: JDO
Issue Type: Bug
Components: specification
Affects Versions: JDO 3.2.1
Reporter: Tilmann Zäschke
The specification does not clearly specify the behavior of the Q classes in
Section "14.10 Typesafe Query Construction"
The examples in section "14.11 Examples" use the following methods of generated
Q-classes:
* candidate()
* candidate(String)
* variable(String)
Specific points that we should possibly mention:
* These methods should allow Q classes to be used concurrently. Specifically,
they should all return *new* instances. The current specification allows
returning shared multiple instances which causes problems when used
concurrently. (the reference implementation currently does this for
'candidate()').
* The reference implementation also has a 'parameter(String)' method. We may
want to add this to the spec.
