Subject [jira] [Commented] (FELIX-5614) Make isDTOType(Class<?> cls) publicly available
Date Tue, 18 Apr 2017 23:40:41 GMT

    [ https://issues.apache.org/jira/browse/FELIX-5614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15973744#comment-15973744

David Leangen commented on FELIX-5614:
--------------------------------------

Just a thought...

On a related not, what would you think about providing the ability to inject the "isDTOType"
rule into the Converter implementation?

Of course, the default would be compliant to the DTO spec, but it would also allow people
(ahem, like me) to use non-compliant rules. For instance, I find it very practical to have
a non-default constructor, but this is not DTO compliant.

  (Related issue: https://osgi.org/bugzilla/show_bug.cgi?id=212)

Having the ability to inject the rule will allow people like me to use their own custom version
of the "isDTO" test, so it wouldn't be necessary to continuously have to call "source/targetAsDTO"
every single time.

> In ConvertingImpl, which a (bundle private) implementation class, there is a (class private)
method: isDTOType(Class<?> cls)
> Since this is a rule based on the definition of a DTO in the spec, it would be nice to
make this test somehow available publicly for general use (including by other bundles).
> It tedious for each user of the API to write their own test if an authoritative test
is already available.
> For my particular use case, the Schematizer needs to test a class to determine whether
or not it is a DTO in order to know how to handle it. Having the test available (without having
to copy over the code from the Converter) would be quite useful..
