Why would specifying "fm.config.sites" work & "fm.config.sites.networks" not work for base class?

[Eric Peters]

Weird, not sure if its a bug or what, but here's the behavior I'm seeing

scala> val ref = new Reflections("fm.config.sites.networks")

ref: org.reflections.Reflections = org.reflections.Reflections@4480e1f8

scala> ref.getSubTypesOf(classOf[fm.model.Site])

res1: java.util.Set[Class[_ <: fm.model.Site]] = []

(doesn't work - empty set)

vs

scala> val ref = new Reflections("fm.config.sites")

ref: org.reflections.Reflections = org.reflections.Reflections@6e3409ba

scala> ref.getSubTypesOf(classOf[fm.model.Site])

res2: java.util.Set[Class[_ <: fm.model.Site]] = [class fm.config.sites.networks.yearone, class fm.config.sites.networks.tirerack, class fm.config.sites.networks.A18G8GVWHHIMY9, class fm.config.sites.networks.pdmautoparts, class fm.config.sites.networks.autohausaz, class fm.config.sites.networks.oereplacement, class fm.config.sites.networks.A3S8PGWS6GY5FN, class fm.config.sites.networks.andysautosport, class fm.config.sites.networks.primechoiceautoparts, class fm.config.sites.networks.empirecovers, class fm.config.sites.networks.A39H7TJSTSYZEU, class fm.config.sites.networks.autoparts123, class fm.config.sites.networks.A1J7OTSURZAVWI, class fm.config.sites.networks.superatv, class fm.config.sites.networks.A2LQ036XGSZPVD, class fm.config.sites.networks.autopartsexpress, class fm.config.s...

Works fine.

As you can see the classes are actually in the package fm.config.sites.networks, so shouldn't specifying the base class fm.config.sites.networks work?

Thanks,

new Reflections("fm.config.sites.networks") is actually equivalent to new Reflections(ClasspathHelper.forPackage("fm.config.sites.networks"), new FilterBuilder().include("fm.config.sites.networks"))

so the path is treated as base package.

what you probably need is new Reflections(ClasspathHelper.forPackage("fm.config.sites.networks"))

Very interesting that does appear to work

The javadocs might need to be updated to describe when you pass in the "string" as an Object into the constructor.  I didn't see any reference to FIlterBuilder: http://reflections.googlecode.com/svn/trunk/reflections/javadoc/apidocs/org/reflections/Reflections.html

What exactly is FilterBuilder, and what is the .include() doing there that makes it behave differently than calling "new Reflections(ClasspathHelper.forPackage("fm.config.sites.networks"))" directly?

Thanks,
