  • y

    yole

    11/05/2015, 2:27 PM
    yes

    and null = true is true?
  • y

    yole

    null
    is equal to 
    null
    and not equal to any non-
    null
    value

    null == true
    is also false

    Boolean.TRUE == null
    is false, and 
    Boolean.FALSE == null
    is also false

    what you need is 
    != true

    if its 
    false
    or 
    null
    , this will return true, else it will return false

    I suggest you try it in the REPL or a unit test

    Is there a way to avoid 
    ApiControllerImpl.INSTANCE
    call from Java?

    You can export Companion object’s members as static using @JvmStatic annotation

    so same goes for comparing a nullable with any kind of value, its false as long as its not the value

  • n

    nickst

    11/05/2015, 2:49 PM
    sorry var someVar = someObject?.someValue? it returns null or cancells the assignment

    hey guys! Is anyone here using Kotlin with Proguard? If so, can you share the proguard rules that you use so that Kotlin works?

    Copy code
    -keep class kotlin.dom.** { public *; }
-dontwarn kotlin.dom.**
