Add a warning to the documentation of EventBus about generics #1878

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The documentation of EventBus states that
"Events are routed based on their type — an event will be delivered to any 
subscriber for any type to which the event is assignable."

This is not true for generics (a Foo<Y> will also be delivered to @Subscribe 
to(Foo<X>) even though Foo<Y> is not assignable to Foo<X>). So, instead of 
making the programmer wonder how EventBus could possibly guess the erased 
generic information, it would be helpful to warn that it cannot.
