------------------------------------

             Summary: Changing the signature of 
JDOQLTypedQuery.numericParameter, listParameter, setParameter, and mapParameter
                 Key: JDO-777
                 URL: https://issues.apache.org/jira/browse/JDO-777
             Project: JDO
          Issue Type: Improvement
          Components: api
    Affects Versions: JDO 3.1
            Reporter: Michael Bouschen
             Fix For: JDO 3.2


Class JDOQLTypedQuery provides a method to create a numeric patameter for a 
query:

{{NumericExpression<?> numericParameter(String name);}}

This signature does not support the creation of a numeric parameter of type 
NumericExpression<Double> that is then used in methods like lt or gt taking a 
double field as an argument. 

I propose to add an overloaded method with the following signature:

{{<{color:#20999d}N{color}> NumericExpression<{color:#20999d}N{color}> 
numericParameter(Class<{color:#20999d}N{color}> type, String name);}}

I propose a corresponding extension for methods collectionParameter, 
mapParameter and listParameter:

{{<{color:#20999d}E{color}> 
CollectionExpression<Collection<{color:#20999d}E{color}>, 
{color:#20999d}E{color}> collectionParameter(Class<{color:#20999d}E{color}> 
elementType, String name);}}

{{<{color:#20999d}K{color},{color:#20999d}V{color}> 
MapExpression<Map<{color:#20999d}K{color},{color:#20999d}V{color}>, 
{color:#20999d}K{color}, {color:#20999d}V{color}> 
mapParameter(Class<{color:#20999d}K{color}> keyType, 
Class<{color:#20999d}V{color}> valueType, String name);}}

{{<{color:#20999d}E{color}> ListExpression<List<{color:#20999d}E{color}>, 
{color:#20999d}E{color}> listParameter(Class<{color:#20999d}E{color}> 
elementType, String name);}}
