Object CollectionInitializer

  • All Implemented Interfaces:
    
public class CollectionInitializer

    Quite often many lambda objects are generated during frequent calls like getOrPut:

    class MyClass {
    private val cache = mutableMapOf<String, Stack<MyData>>()

    fun service(key: String) {
        cache.getOrPut(key) { Stack<MyData>() }
    }
}

    That way it's more effective pre-defining initializers and use them like below - by doing that we avoie unnecessary lambda objects construction:

    cache.getOrPut(key, CollectionInitializer.stack())
