Tiny Types–documentation–part 4

This is a series

tiny types in C#

Tiny types is a NuGET dll,https://www.nuget.org/packages/TinyTypesObjects/

Also,you can find the construction here: http://msprogrammer.serviciipeweb.ro/category/tinytypes/

The documentation is copied shameless from https://github.com/jan-molak/tiny-types

Installation

To install the module from nuget : … Install-Package TinyTypesObjects …

Defining Tiny Types

An int on its own is just a scalar with no meaning. With an object,even a small one,you are giving both the compiler and the programmer additional information about what the value is and why it is being used.

‐ Jeff Bay,Object Calisthenics

Single-value types

To define a single-value TinyType – extend from TinyType<T>() :

If you want operator ==,please use TinyTypeOf or TinyTypeOfString

using TinyTypesObjects;

public class Age : TinyTypeOf<int>
    {
        public Age(int nr) : base(nr)
        {

        }
    }
public class FirstName : TinyTypeOfString
    {
        public FirstName(string str) : base(str)
        {

        }
    }

Every tiny type defined this way has a get property value of type T,which you can use to access the wrapped primitive value. For example:

var firstName = new FirstName("Jan");

Assert.AreEqual(firstName.value,"Jan");

Converting from / to original values

There are defined conversions between type T and the class

public void TestConvert()
        {
            string s = "http://msprogrammer.serviciipeweb.ro";
            TinyTypeOfString tt = s;
            Assert.AreEqual(s,(string)tt);

            int nr = 7;
            TinyTypeOf<int> tt1 = nr;

            Assert.AreEqual(nr,(int)tt1);
        }

so the following code should work for the class with constructor string

class TestConstructor
    {
        public TestConstructor(string firstName)
        {
            FirstName = firstName;
        }

        public string FirstName { get; }
    }
[TestMethod]
        public void TestConstructor()
        {
            var firstName = new FirstName("Jan");
            TestConstructor tc = new TestConstructor(firstName);
            Assert.AreEqual(tc.FirstName,"Jan");
        }

Equals or ==

Each tiny type object has an equals method,which you can use to compare it by value:

int nr = 7;
            TinyTypeOf<int> tt1 = nr;
            TinyTypeOf<int> tt2 = nr;

            Assert.AreEqual(tt1,tt2);
            Assert.IsTrue(tt1 == tt2);
