日期

2002 Handles name-based creation of objects.

在文件 factory.h 第 46 行定义.

构造及析构函数说明

template<class Base >

libMesh::Factory< Base >::Factory ( const std::string &  name )

inlineprotected

Constructor.

Takes the name to be mapped.

在文件 factory.h 第 116 行定义.

{
  // Make sure we haven't already added this name
  // to the map
  libmesh_assert (!factory_map().count(name));

  factory_map()[name] = this;
}

template<class Base>

virtual libMesh::Factory< Base >::~Factory ( )

virtualdefault

Destructor.

成员函数说明

template<class Base >

std::unique_ptr< Base > libMesh::Factory< Base >::build ( const std::string &  name )

inlinestatic

Builds an object of type Base identified by name.

在文件 factory.h 第 129 行定义.

参考 libMesh::Factory< Base >::create() , 以及 libMesh::err.

{
  // name not found in the map
  if (!factory_map().count(name))
    {
      libMesh::err << "Tried to build an unknown type: " << name << std::endl;

      libMesh::err << "valid options are:" << std::endl;

      for (const auto & pr : factory_map())
        libMesh::err << "  " << pr.first << std::endl;

      libmesh_error_msg("Exiting...");
    }

  Factory<Base> * f = factory_map()[name];
  return std::unique_ptr<Base>(f->create());
}

template<class Base>

virtual std::unique_ptr<Base> libMesh::Factory< Base >::create ( )

pure virtual

Create a Base class.

Force this to be implemented later.

在 libMesh::FactoryImp< Derived, Base > 内被实现.

参考自 libMesh::Factory< Base >::build().

template<class Base>

static std::map<std::string, Factory<Base> *>& libMesh::Factory< Base >::factory_map ( )

staticprotected

Map from a name to a Factory<Base> * pointer.
