garyp / ifnull.kt
Created August 8, 2019 18:43
Kotlin `ifNull` and `ifNullAlso` functions
/**
* If [this] is not null, returns [this]. Otherwise returns the result of calling [block].
*
* This function can be used in two ways:
* 1. [block] provides a fallback value when [this] is null.
* 2. [block] provides an early return from the enclosing method when [this] is null:
* ```
* fun foo() {
* functionThatMightReturnNull().ifNull {
* log.warn("Got a null value")
