07/17/2017, 9:46 AMThe sample get's the context from the application through a static method - p

07/17/2017, 9:47 AMIf you want to inject the context, you need to use a regular class with a private constructor and have a getInstance method which performs the initialization lazily - u

07/17/2017, 3:15 PMwhy doesn't smart-cast work on the following scenarioCopy codedata class Foo(val bar: Int?, val fizz: Int?) { val myVal get() = bar.takeIf { fizz != null } } ________ val myFoo = Foo(1, 2) val myBool = myFoo.myVal != null && myFoo.myVal > 5 <--- '>' cannot be applied to the types involved - m
menegatti
07/17/2017, 3:16 PMI assume that it doesn't work with custom getter? - r
Ruckus
07/17/2017, 3:16 PMCorrect - m
menegatti
07/17/2017, 3:38 PManother question... you can override the mutability of a variable defined in an interfaceCopy codeinterface A { val b : Int } class B { override var b: Int = 0 } - m
menegatti
07/17/2017, 3:38 PMcan you make it work from Java? - m
menegatti
07/17/2017, 3:38 PMmeaning, a Java class overriding that interface can allow for a setter on that variable? - r
Ruckus
07/17/2017, 3:39 PMWouldn't you just create a
method?setB - k
kevinmost
07/17/2017, 3:39 PMin Java, yeah. In Kotlin you can also override `val`s with `var`s - k
kevinmost
07/17/2017, 3:39 PMsince really, under the hood, a setter is just getting generated in the overriding class - m
menegatti
07/17/2017, 3:40 PMthe IDE is complaining that you cannot set that variable - m
menegatti
07/17/2017, 3:40 PMactually, it complains if you try to set the variable directly, but not through the setter - m
menegatti
07/17/2017, 3:40 PMgo figure... - r
Ruckus
07/17/2017, 3:41 PMInteresting. You may want to submit a bug. - m
