Doxygen：防止由于前向声明和模板导致的重复

Question

Doxygen generally handles forward declarations well. For example,

/** \file */

class A;

class B {
    // uses A
};

class A {
    // uses B
};

results in

without duplicating A .

But if I make A and B class templates, then A is extracted twice:

/** \file */

template<typename T> class A;

template<typename T>
class B {
    // uses A<T>
};

template<typename T>
class A {
    // uses B<T>
};

How can I prevent this?

Answer 1

With the versions 1.8.13 - 1.8.18 I can see the behavior as indicated. With the current doxygen master, ie 1.8.19 (0937faf2d168b64f5ccf55c1976bc045d5d12569), this problem looks like to be solved and only class B<T> and class A<T> are shown.

(It is not yet known / planned when 1.8.19 will be released, the 1.8.18 version has been released on April 12, 2020).
