📝 Template Method

Template Method


The template method pattern defines the steps of an algorithm and allows the redefinition of one or more of these steps. In this way, the template method protects the algorithm, the order of execution and provides abstract methods that can be implemented by concrete types.

Example

protocol Garden {
    func prepareSoil()
    func plantSeeds()
    func waterPlants()
    func prepareGarden()
}

extension Garden {
    func prepareGarden() {
        prepareSoil()
        plantSeeds()
        waterPlants()
    }
}

final class RoseGarden: Garden {

    func prepare() {
        prepareGarden()
    }

    func prepareSoil() {
        print ("prepare soil for rose garden")
    }

    func plantSeeds() {
        print ("plant seeds for rose garden")
    }

    func waterPlants() {
       print ("water the rose garden")
    }
}

Contacts
I have a clear focus on time-to-market and don't prioritize technical debt. And I took part in the Pre-Sale/RFX activity as a System Architect, assessment efforts for Mobile (iOS-Swift, Android-Kotlin), Frontend (React-TypeScript) and Backend (NodeJS-.NET-PHP-Kafka-SQL-NoSQL). And I also formed the work of Pre-Sale as a CTO from Opportunity to Proposal via knowledge transfer to Successful Delivery.
