[solved] need my class with a <type> extension
I like to create a class which is (amongst others) able to store a single number, to represent a datapoint. Now, becouse the some data could be more important than other, I like to give the (end-)user a choice if my class should store the data as int, float or double.
Unfortunately I have no idea how to do that. And (even more bad) I have no Idea how to name my problem to google it.
Becouse I have no Idea of the name for my problem, here a Example:
QList<int> myIntList; // store data as integer
QList<float> myFloatList; // store data as float
QList<double> myDoubleList; // store data as double
I need something similar:
Datapoint<int> myIntData; // store data as integer
Datapoint<float> myFloatData; // store data as float
Datapoint<double> myDoubleData; // store data as double
First question: What is the name of these <TYPE>? I guess I need some basics here.
Secound question: How can I create a class whis has these <TYPE>? (may be anserd automaticaly if I read the basics from question 1).
