Template Method Pattern

A pattern where a base class fixes the steps and child classes fill some of them in.

What is Template Method Pattern?

The Template Method pattern puts the fixed steps of a process in a base class and lets child classes fill in certain steps. Every report is "header, body, footer", but the body differs.

public abstract class Report
{
    public string Build() => Header() + Body() + Footer();
    protected string Header() => "ACME Corp\n";
    protected abstract string Body();
    protected string Footer() => "\n-- end --";
}
