parent class is executed. 3) a more complex Hook method can be used to constrain other methods. This Hook method usually returns a boolean type, that is, true or false, to determine whether to execute a basic method. The subclass determines whether to call the Hook method.

1. Main version template classFirst we look at a beginner can understand, the application of the template program:1 #include The program is simple, a template Class A, which has a function to print two parameters. We created the object of Class A with the Int,char type in the main function, and after calling the functi
[Conversion] Traits programming techniques + template skewness + template parameter derivation + embedded type programming techniques, traitstemplate
In STL, traits programming techniques have been greatly applied. Only by understanding this can we have a glimpse of the mysteries of STL.
First, record what you understand as follows:
Traits technology can be used
The implicit (implicit) type conversion of template functions involves the determination of template parameters (TypeName).
from type int or double, cannot be implicitly converted to the type of the template class (
remaining logic. Different subclasses can implement these abstract methods in different ways, thus having different implementations of the remaining logic. First, a top-level logical framework is established, and the details of the logic are left to specific subclasses to implement.

One, type conversion and template type parametersTemplates, like function calls, use arguments passed to a template to initialize the template's formal parameters, except that the parameter is a template parameter and is usually a type
An example is1 int 2 class Stack {};Here I think of the C language is how to get the data structure, have to say the template is very convenient things. The above example is a class template, and the function template is actually similar.Floating-point numbers and class objects are not allowed as non-type
Non-type template parameters (nontype template parameters), you can use an integral type (integral type), a pointer (pointer), or a reference (reference);
The argument (argument) of a bound untyped integer parameter (nontype integral parameter) must be a constant expression
In the template, apart from defining type parameters, we can also define non-type parameters. For example:
Temlate
Note that the compiler inserts an empty character at the end of a string literal constant as the final character.
For example, we call
Foo ("hi", "mom ");
In fact, the compiler will instantiate the following versions:
Int Foo (const char (P1)
C ++ template metaprogramming 7: traits class for Type judgment, template traits2. traits class used to determine the type
The is_void class can be used to determine the type of template parameters. It is easy to use. You can als
Using string. Template, we can customize the string replacement standard for Python. here we will use the example to parse the Template-type string Template usage in the string Module of Python:
String. Template ()Add replacement characters in string.
The template parameters do not have to be all types.
When a function is called, non-type parameters are replaced by values. The value type is specified in the template parameters table.
E.g .:
# Include

String. Template ()Add replacement characters in string. Template (), use the "$" symbol, or use the "$ {}" character in the string. Use the string. substitute (dict) function for calling.
