Template

Breathe has support for class and function templates. They are output as follows. For a class with a single template parameter:

.. doxygenclass:: templateclass
   :project: template_class
   :members:

It renders as:

template<typename T>
class templateclass

a class with a template parameter

Template Parameters:

T – this is the template parameter

Public Functions

inline templateclass()

default constructor

inline templateclass(T const &m)

constructor with template argument

Parameters:

m – the argument

T method(T const &t)

member accepting template argument and returning template argument

Parameters:

t – argument of type T

Returns:

returns value of type T

With multiple template parameters it renders as:

template<typename T, typename U, int N>
class anothertemplateclass

a class with three template parameters

Template Parameters:

  • T – this is the first template parameter

  • U – this is the second template parameter

  • N – this is the third template parameter, it is a non-type parameter

Public Functions

inline anothertemplateclass()

default constructor

inline anothertemplateclass(T const &m1, U const &m2)

constructor with two template argument

Parameters:

  • m1 – first argument

  • m2 – second argument

U method(T const &t)

member accepting template argument and returning template argument

Parameters:

t – argument

Returns:

returns value of type U

A function with single template parameter renders as:

template<typename T>
T function1(T arg1)

a function with one template arguments

Template Parameters:

T – this is the template parameter

Parameters:

arg1 – argument of type T

Returns:

return value of type T

If specialized for a given type it renders as:

template<>
std::string function1<std::string>(std::string arg1)

a function with one template argument specialized for std::string

Parameters:

arg1 – argument of type std::string

Returns:

return value of type std::string

With multiple template parameters it renders as:

template<typename T, typename U, int N>
T function2(T arg1, U arg2)

a function with three template arguments

Template Parameters:

  • T – this is the first template parameter

  • U – this is the second template parameter

  • N – this is the third template parameter, it is a non-type parameter

Parameters:

  • arg1 – first argument of type T

  • arg2 – second argument of type U

Returns:

return value of type T
