Compiler check for base type agreement between the type and typeHint attributes
of an action output annotation
--------------------------------------------------------------------------------------------------------------
Key: BEEHIVE-929
URL: http://issues.apache.org/jira/browse/BEEHIVE-929
Project: Beehive
Type: Improvement
Components: NetUI
Versions: TBD
Reporter: Troy Beecroft
Priority: Minor
Tools can use the typeHint attribute on an action output annotation to preserve
information about parameterized types. Such tools might jointly manage both
the type and typeHint attribute to keep them in synch. Even so, someone could
change one and not the other either directly in source or via a property sheet.
In such cases it would be really handy if there was a compiler check to see
that both attributes have the same base type.
As an example, the following annotation would pass:
@Jpf.ActionOutput(name="customers", type=java.util.ArrayList.class,
typeHint="java.util.ArrayList<businessObjects.Customer>
while this one would not:
@Jpf.ActionOutput(name="customers", type=java.util.ArrayList.class,
typeHint="java.util.List<businessObjects.Customer>
