Smart Pointer Map Lookup

[Peter_APIIT]

Hello to all, i have a smart pointer declare like this.

shared_ptr<Human> HumanPtr;

The class Human has several derived classes such as Admin, Staff and HR.

I have another class called commander has shared_ptr<Human> HumanPtr as member.
The class commander has a map lookup table the declare like

ypedef std::map<HumanPtr, GenericCommandPtr> commandCont;

I wan to lookup the appropriate GenericCommandPtr based on the member HumanPtr and forward to the GenericCommandPtr derive class.

My code:

Commander commandPtr(thePtr);
commandPtr.ForwardCommand(); 

class Commander
{
private:
	typedef boost::shared_ptr<GenericCommander> GenericCommandPtr;
	typedef boost::shared_ptr<Human> HumanPtr;
	typedef std::map<HumanPtr, GenericCommandPtr> commandCont;
	
	// Lookup table like vtable
	commandCont theCommander;
	HumanPtr theRealUserPtr;

public:
	Commander();
	explicit Commander(const HumanPtr&);
	~Commander();

	void RegisterCommanderInstance();
	void ForwardCommand();

};



Commander::Commander() 
		: theCommander(commandCont()), 
				theRealUserPtr(HumanPtr())
{
}
// =========================================
Commander::Commander(const HumanPtr& userInstancePtr)
		: theCommander(commandCont()),
		  theRealUserPtr(userInstancePtr) 
{
}
// =========================================
Commander::~Commander() 
{
}
// =========================================
void Commander::RegisterCommanderInstance()
{
	static shared_ptr<Administrator> AdministratorPtr(new Administrator());
	static shared_ptr<HumanResource> HumanResourcePtr(new HumanResource());
	static shared_ptr<Staff> StaffPtr(new Staff());
	
	static GenericCommandPtr AdministratorCommandPtr(new AdministratorCommander() );
	static GenericCommandPtr HRCommandPtr(new HRCommander() );
	static GenericCommandPtr StaffCommandPtr(new StaffCommander() );

	theCommander.insert(commandCont::value_type(AdministratorPtr, AdministratorCommandPtr) );
	theCommander.insert(commandCont::value_type(HumanResourcePtr, HRCommandPtr) );
	theCommander.insert(commandCont::value_type(StaffPtr, StaffCommandPtr) );
}
// =========================================
void Commander::ForwardCommand()
{
	theCommander.find(theRealUserPtr)->second; 
}

void Commander::ForwardCommand()
{
	theCommander.find(theRealUserPtr)->second; 
}

This code cause run time error map iterator not deference able.

The purpose of this program is to look up the appropriate GenericCommandPtr class.

Please help.

It really urgent.

Thanks.
