Arrays (T[])

Arrays of items are represented with the most common, and most efficient array datastructures in native languages, such as std::vector<T> or Array<T>.

TypeScript

interface Contacts extends HybridObject {
  getAllUsers(): User[]
}

C++

class HybridContacts : public HybridContactsSpec {
  std::vector<User> getAllUsers();
}

Swift

class HybridContacts: HybridContactsSpec {
  fun getAllUsers() -> Array<User>
}

Kotlin

class HybridContacts: HybridContactsSpec() {
  fun getAllUsers(): Array<User>
}

Kotlin PrimitiveArray

As a performance improvement, the JNI (C++ -> Kotlin interface) provides Primitive Array datatypes which can avoid boxing primitives into Objects, and provides bulk copy methods. This makes all array operations a lot faster, and Nitrogen is smart enough to ✨automagically✨ use Primitive Arrays whenever possible. This will replace the following arrays:

• Array<Double> -> DoubleArray
• Array<Boolean> -> BooleanArray
• Array<Long> -> LongArray
