我有声明（或类似）
std::map< std::string, Stock*> &stocks;
贯穿我的代码。 Eclipse不喜欢这样，并产生“无效的模板参数”错误。
股票声明为：
class Stock {
public:
Stock(std::string, qbbo::Financial_status_indicator, qbbo::Security_class,
qbbo::Current_trading_state,
qbbo::Market_category, qbbo::Reg_sho_action);
~Stock();
void setFinancialStatusIndicator(qbbo::Financial_status_indicator financialStatusIndicator);
void setSecurityClass(qbbo::Security_class securityClass);
void setCurrentTradingState(qbbo::Current_trading_state tradingState);
void setMarketCategory(qbbo::Market_category marketCategory);
void setREGShoAction(qbbo::Reg_sho_action regSHOAction);
bool isStockTrading();
private:
enum StockState {
STOCK_STATE_OK, STOCK_STATE_UNKNOWN, STOCK_STATE_UNEXPECTED_CHARACTERISTIC
};
std::string name;
int inventory;
StockState currentState;
// Expected values initialised in constructor
qbbo::Financial_status_indicator expectedFinancialStatusIndicator;
qbbo::Security_class expectedSecurityClass;
qbbo::Current_trading_state expectedCurrentTradingState;
qbbo::Market_category expectedMarketCategory;
qbbo::Reg_sho_action expectedRegSHOAction;
// Actual values as set by messages
qbbo::Financial_status_indicator financialStatusIndicator;
qbbo::Security_class securityClass;
qbbo::Current_trading_state currentTradingState;
qbbo::Market_category marketCategory;
qbbo::Reg_sho_action regSHOAction;
void nextState();
};
我看不出这个宣言的内容是否有效，编译得很好。有没有我缺少的东西，Eclipse正在捕捉？
简短的自包含正确的例子
#include <string>
#include <map>
#include "stock.h"
int main() {
std::map<std::string, Stock*> stocks;
}
