接着你就可以使用FLAGS_name变量了,这些变量的值则是由命令行参数传递,无则为默认值, 在其他代码文件中若想用该命令参数,可以用DECLARE_int32(name)声明(name为int32类型,也可以使用其他支持的类型)。 在caffe.cpp中有很多FLAGS_name定义,如DEFINE_string(gpu,"","some description"),则命令行后-gpu 0,表示FL...
In the interface I forward declare a structure (important because I don't want to drag other stuff in the interface), but I include its definition in the cpp file which defines the interface. Interface.h #ifndefINTERFACE_H_INCLUDED#defineINTERFACE_H_INCLUDED// forward declarationclassForwardDecl...
The Google C++ coding guidelines specifically recommend including the associated header first. It is good practice for foo.hpp to declare everything that foo.cpp exports, and for everything else in foo.cpp to have internal linkage in order to not pollute the global namespace. ...
Exposed classes can declare factories with ".factory". A factory is a c++ function that returns a pointer to the target class. It is assumed that these objects are allocated with new on the factory. On the R side, factories are called just like other constructors, with the "new" function...

- Declare `obj` without an initializer, such as `obj: some_type;`. This allocates stack space for the object, but does not construct it. - `obj` must have a definite first use on every `#!cpp if`/`#!cpp else` branch path, and - that definite first use must be of the form ...

Generated API documentation is planned. Until then the code itself (which is pretty readable outside of thedetailnamespace) and examples/unit tests should hopefully be enough to use this library. License SeeLICENSE.md. Copyright © 2022Mikael Simonsson. ...
<<深入浅出MFC>>这本书对MFC框架中宏的使用解析的很透彻,也让我们领略到宏的强大功能。可以参看DECLARE_MESSAGE_MAP(), BEGIN_MESSAGE_MAP,END_MESSAGE_MAP的实现。 4)#pragma的使用,例如用#pragma禁止掉无伤大雅的警告,用于可移植性的条件编译中。例如, ...
