Learning Concurrency in Kotlin

Adding the search function

The second step is to add the logic to do the searches properly. Let's create the package co.starcarr.rssreader.search and place the file Searcher.kt inside it:

Now we will create the class Searcher inside it, and include a function that will return a ReceiveChannel<Article>, given a query. Notice that we want to return a ReceiveChannel so that the caller doesn't use this channel to send information:

class Searcher() {    fun search(query: String) : ReceiveChannel<Article> {        val channel = Channel<Article>(150)        return channel    }}
