我打算写一个适配器类.在这个类中有一个xmlrpc-c服务器(深渊服务器).我想通过创建一个新线程来启动服务器,而线程的函数是成员函数
XMLThreadFun().
当我尝试使用下面的代码时,在适配器的构造函数实现的行上有一个错误：
/usr/include/boost/bind/bind.hpp:69:37: error: ‘void (Adapter::*)()’ is not a class,struct,or union type
谁能告诉我如何解决这个错误,或者如何实现我的目标？对此,我真的非常感激.
以下是我的代码片段：

#include "config.h"

#include "quickfix/FileStore.h"

using namespace std;
class theClient : public xmlrpc_c::method {
public:
theClient() {}
theClient(FIX::SocketInitiator* initiator) {
set<FIX::SessionID> s(initiator->getSessions());
set<FIX::SessionID>::iterator myIterator;
for (myIterator = s.begin(); myIterator != s.end(); myIterator++) {
string str(myIterator->getSenderCompID());
clientname = str;
}
}
void execute(xmlrpc_c::paramList const& paramList,xmlrpc_c::value * const retvalP) {
*retvalP = xmlrpc_c::value_string(clientname);
}
private:
string clientname;
};
class Adapter {
private:
xmlrpc_c::registry myRegistry;
xmlrpc_c::methodPtr XMLRPCMethodP;
xmlrpc_c::serverAbyss webServer;
boost::thread webServerThread;
public:
void initWebServer(string rpcHost,string rpcPort);
void XMLThreadFun();
Adapter(string rpcHost,string rpcPort);
};
Adapter::Adapter(string rpcHost,string rpcPort) : myRegistry(),XMLRPCMethodP(new theClient),webServer(myRegistry,8181,"/tmp/xmlrpc_log"),webServerThread(boost::bind(&Adapter::XMLThreadFun,this,&webServer))
{
initWebServer(rpcHost,rpcPort);
}
void Adapter::XMLThreadFun() {
webServer->run();
}
void Adapter::initWebServer(string rpcHost,string rpcPort) {
webServerThread.join();
}
解决方法
您将需要使用boost :: bind将成员函数作为线程调用.
就像是
就像是
class MyClass {
public:
void Start();
void DoStuff( int limit );
};
MyClass foo;
boost::thread thread1( boost::bind( &MyClass::Start,&foo ) );
boost::thread thread2( boost::bind( &MyClass::DoStuff,&foo,30 ) );
// threads do stuff here
thread1.join();
thread2.join();
具体来说,看起来你会改变
webServerThread( boost::bind( &Adapter::XMLThreadFun,&webServer)
至
webServerThread( boost::bind( &Adapter::XMLThreadFun,this )
