Introduction Reflection and structs Reflection and struct tags Reflections and interfaces In the previous, we took a big step in understanding how reflection works in the Go language. Now we will dive deeper into the topic by covering how to use reflection with structs and interfaces. In this lecture, we will start by explaining how reflection needs structs And then we'll explore struct tags..

In the previous lesson, we had a healthy dosage of practical Go programming. When we finished writing our chat client for the hydra spaceship. In this section we'll begin to explore reflection in the Go language. We are going to take a look at.. What is Refelction Refresher on interfaces First law of reflection Second law of reflection Third law of reflection http://blog.golang.org/laws-of-r..

Hydrachat.go package hydrachat import ( "fmt" "net" "os" "os/signal" "syscall" "github.com/gopythor/udemy/Hydra/hlogger" ) var logger = hlogger.GetInstance() //Start hydra chat func Run(conneciton string) error { l, err := net.Listen("tcp", connection) r := CreateRoom("HydraChat") if err != nil { logger.Println("Error connection to chat client", err) return err } go func() { //Handle SIGINT and ..

The Pipeline Pattern https://blog.golang.org/pipelines A concurrent pattern A series of 'stages' connected by channels Each stage is a group of goroutines running the same function So what is the pipeline design pattern and detailed article covering the pattern can be found in the link shown here. Pipeline is a design pattern that makes have used of go's concurrency. And devides code..

Go Concurrency Composition of multiple independent operations. Goroutine : An independently executed function, launched by the goroutine. Goroutines are cheap threads, but not reaparallel. Go channel : A way for goroutines to communicate. Go channels block till data is sent. Buffered Go channels block only when the buffer is full. So let's take a refresher into how concurrency works in Go. Concu..

Durations Number of nanoseconds between two times instances Go's way to identify time durations Examples: 3*time.Second => time duration of 3 seconds 3*time.Minute => time duration of 3 minutes So what are the relations. The Duration is a special type in go that can describe a time duration based on the number of nanoseconds. Between the start and the end time the type exists in the time package..

So even though Go prefers channels and go routines for concurrent tasks. There are cases where locking memory is inevitable. So in go to access any functionality related to thread Locking we need to use the sync package which is a standard package in go as shown here. So there are numerous features enabled by sync. However for us we will focus on the most useful and commonly used features can ge..

What is the Singleton Pattern An object gets created only once then reused. Let's start by defining the singleton design pattern that is simply and object that get created only once in our code. And then gets used again and again We don't create multiple instances often. Why use the Singleton Pattern When the object needs to keep state throughout our program. The singleton pattern is useful when..
