Hi Christian
If you have something like
MyType<Integer>
then the generic type will help the converter implementation to figure
out that MyType is parameterized by Integer.
If you have List<MyType<Integer>> then as I noted earlier the List will
be created by the runtime while individual matrix/query etc properties
will be converted to MyType<Integer> by the converter

Hi all,
This is probably the wrong place, but...
Can anyone explain to me in plain simple English what the genericType
parameter below is good for, please?
public class FooHandler implements ParamConverterProvider {
@Override
public <T> ParamConverter<T> getConverter(final Class<T> rawType,
Type genericType, Annotation[] annotations) {
I'm afraid I don't quite understand the JavaDoc from
https://docs.oracle.com/javaee/7/api/javax/ws/rs/ext/ParamConverterProvider.html
- and I couldn't find an example anywhere...
From the docs:
genericType - the type of object to be converted. E.g. if an String value
representing the injected request parameter is to be converted into a method
parameter, this will be the formal type of the method parameter as returned by
Class.getGenericParameterTypes. <<
From that, I would have expected that for this method signature:
public Response foo(@MatrixParam("l") List<String> myList) {
genericType would be String?
As in:
if an String value ["abc"] representing the injected request parameter [";l", i.e. ";l=abc"] is
to be converted into a method parameter [myList], this will be the formal type [<String>] of the method parameter
[List<String>] as returned by Class.getGenericParameterTypes. <<
Am I close?
Kind regards,
Christian
