01-11-2016 Abstract types / Strict typing for stringly-typed extern code
A common pattern, often found in (but not only in) dynamic languages, is to denote the type of some object with a string, for example:
01-11-2016 Abstract types / Color as abstract type
The following example demonstrates how a color type can be abstracted over an integer, which stores the color in an ARGB format.
01-11-2016 Abstract types / Email address as abstract type
The following EmailAddress Abstract type example is based on the underlying standard String type, but sets the restriction that it can only represent a valid email address. If not, an exception will be thrown.
01-11-2016 Abstract types / Rounded Float as abstract type
This abstract type is based on the underlying Float type, but whenever it is converted back to an actual Float it is rounded to avoid the famous rounding errors occuring in floating point aritmetics.
01-11-2016 Abstract types / Temperature units as abstract type
The following Celcius and Fahrenheit Abstract types are based on the underlying Float type, but sets the restriction that it can never hold values below absolute zero.
