![]() ![]() While chaining other functions like after takeIf and other default functions like takeUnless is also to be performed with the null checks conditions and the safe call like ‘?.’ Operator because the return value is null. If returns the object and if it does not match the predicate condition the null value if it is does also the object is to be called and available as the lambda argument(it). Else it will return the null values so that the takeIf() method as the filtering function for every single object. The object state infrequent call chains the called objects with the predicate condition provided and takeIf it returns the object if it is matched with the specified conditions. In kotlin language, it has many defaults and standard libraries contain the functions like takeIf, and these functions are let you combined and the value is embedded with checks of the object state and its status. If the condition is satisfied it continues else it returns the null value. ![]() It can be called upon the parameter values and their methods based on the predicate conditions. The above codes are the basic syntax for using the teakeIf() method in the kotlin codes. Val varaiableName:datatype? = kotlinNullable.takeIf(predicate) It’s worth mentioning that, apart from passing a lambda to the any function, we can also pass the contains function’s reference: assertThat(myArray.any(toBeChecked1::contains)).isTrueĪssertThat(myArray.any(toBeChecked2::contains)).isFalse 4.4.Web development, programming languages, Software testing & others fun functionName(parameters) We can combine the any function and the in operator to solve the problem: assertThat(myArray.any ).isFalse Now, we have multiple candidate values to check. We’ve learned that we can check whether an array contains a single given value using the any function or the in operator. ![]()
