Dan Nathanson commented on IBATIS-133:
--------------------------------------
This has been available in iBatis for .NET for a couple of years. It was added
under IBATISNET-155. I would expect that the Java and .NET are very similar in
this area of the framework so the changes should be easily ported. But I
haven't looked at either code line, so that assumption could be totally off
base.
> ResultMap Method Mapping
> ------------------------
>
> Key: IBATIS-133
> URL: https://issues.apache.org/jira/browse/IBATIS-133
> Project: iBatis for Java
> Issue Type: New Feature
> Components: SQL Maps
> Affects Versions: 2.1.0
> Reporter: Brandon Goodin
>
> Method mapping should be supported in ibatis to map to non-javaBean methods.
> Following are some whiteboard ideas for this:
> A standard verbose mapping -
> <resultMap>
> <method
> name="methodName"
> signature="propertyA,propertyB"
> javaTypes="integer,string"
> jdbcTypes="INTEGER,VARCHAR"
> columns="PROPERTY_A,PROPERTY_B" />
> </resultMap>
> If types map cleanly between columns and java types some configuration can be
> avoided -
> <resultMap>
> <method
> name="methodName"
> signature="propertyA,propertyB"
> columns="PROPERTY_A,PROPERTY_B" />
> </resultMap>
> column Indexes should also be supported -
> <resultMap>
> <method
> name="methodName"
> signature="propertyA,propertyB"
> columnIndexes="3,8" />
> </resultMap>
> we could also use the method mapping for constructors as well. Only one
> constructor method type can exist per resultMap. type="method" would be the
> default unspecified method type.
> <resultMap>
> <method
> type="constructor"
> name="methodName"
> signature="propertyA,propertyB"
> columnIndexes="3,8" />
> </resultMap>
> Something else to consider is how a method signature can be mapped to both
> complex objects and simple objects. Perhaps we need to go with a more verbose
> mapping.
> <resultMap>
> <method type="standard" name="methodName">
>
>
>
> </method>
> </resultMap>
> Not sure if we would want to support both or just one type. But, those are
> the ideas.
