Collection Extensions

This section describes how to perform same checks on multiple texts at same time.

Overview

In EasyValidation, you can not only perform multiple validations on same text, but you can also perform same validation on multiple text streams at same time by using Collection Extensions. For example, you are taking a guest invite list of email addresses, and you have to see that all the texts are valid email addresses. Then you can do it like this:

var emailList = listOf("[e-mail]", "[e-mail]", "[e-mail]")

// You can pass any collection via spread operator
var allValid = validEmailList(*emailList, { str, msg ->
    // The str is an invalid text. The msg contains the message here.
})

// Or you can pass any number of arguments directly
var allValid2 = validEmailList("[e-mail]", "[e-mail]", "23ss@", { str, msg ->
    // The str is the invalid text. The msg contains the message here.
})

List of Collection Extensions

The Collection extension methods' names are same as the extension methods names followed by List keyword. For example, validEmail() becomes validEmailList() and so on. These methods accept varargs parameter for multiple texts and an error callback method. Here's list of all the collection extension methods.
