Implement new JDO 2 query tests cases concerning query API Extensions
---------------------------------------------------------------------

         Key: JDO-163
         URL: http://issues.apache.org/jira/browse/JDO-163
     Project: JDO
        Type: New Feature
  Components: tck20  
    Reporter: Michael Watzek
 Assigned to: Michael Watzek 


We need 15 new test classes, one for each of the following assertions:

- A14.5-11: Construct a new query instance using the specified String as the single-string
representation of the query.
- A14.5-12: Construct a new query instance with the given candidate class from a named query.
- A14.5-13: If the named query is not found in already-loaded metadata, the query is searched
for using an algorithm. Files containing metadata are examined in turn until the query is
found. The order is based on the metadata search order for class metadata, but includes files
named based on the query name.
- A14.5-14: If the metadata is not found in the above, a JDOUserException is thrown.
- A14.5-15: The Query instance returned from this method can be modified by the application,
just like any other Query instance.
- A14.5-16: Named queries must be compilable. Attempts to get a named query that cannot be
compiled result in JDOUserException.
- A14.6-21: This method retrieves the fetch plan associated with the Query. It always returns
the identical instance for the same Query instance. Any change made to the fetch plan affects
subsequent query execution.
- A14.6-16: void setResult (String result); Specify the results of the query if not instances
of the candidate class.
- A14.6-17: void setGrouping (String grouping); Specify the grouping of results for aggregates.
- A14.6-18: void setUnique (boolean unique); Specify that there is a single result of the
query.
- A14.6-19: void setResultClass (Class resultClass); Specify the class to be used to return
result instances.
- A14.6-20: setRange(int fromIncl, int toExcl); Specify the number of instances to skip over
and the maximum number of result instances to return.
- A14.6-22: The Unmodifiable option, when set to true, disallows further modification of the
query, except for specifying the range and result class and ignoreCache option.
- A14.6-23: The single string query is first parsed to yield the result, result class, filter,
variable list, parameter list, import list, grouping, ordering, and range. Then, the values
specified in APIs setResult, setResultClass, setFilter, declareVariables, declareParamters,
declareImports, setGrouping, setOrdering, and setRange override the corresponding settings
from the single string query.
- A14.9-1: Some JDO vendors provide extensions to the query, and these extensions must be
set in the query instance prior to execution.
