Aşağıya bkz. Onunla ilgili bir sorun var, çünkü linker Memory'un işlevlerini bulamadığı için şikayet ediyor ama nedenini anlayamıyorum. sınıf/ad memory.h olduğunu beyan EverywhereLinker bir namespace işlevi göremiyor
memory.h
#pragma once
#include "includes.h" //it just includes other strandard headers.
class MemoryUnit
{
public:
MemoryUnit() {}
virtual int getValue() = 0;
virtual int getSize() = 0;
virtual void setValue(int) = 0;
virtual ~MemoryUnit() {};
};
class Byte : public MemoryUnit
{
int value;
public:
static int size;
Byte(int byte) :value(byte) {};
int getSize() { return size; }
int getValue() { return value; };
void setValue(int byte) { value = byte; }
~Byte() {};
};
namespace Memory
{
extern int size;
extern MemoryUnit** map;
void checkAddress(int address);
int read(int adress);
MemoryUnit* getOperation(int address);
void write(int adress, MemoryUnit* data);
void writeByte(int adress, int data);
}
memory.cpp
#include "includes.h"
#include "memory.h"
#include "simulator.h" // it contains only externed constants.
namespace Memory
{
int size = 0;
MemoryUnit** map = NULL;
inline MemoryUnit* getOperation(int address)
{
return map[address];
}
inline void checkAddress(int address)
{
if (address < 0 || address >= MAX_MEMORY_SIZE)
throw std::out_of_range("Invalid memory address.");
}
inline int read(int address)
{
checkAddress(address);
return map[address]->getValue();
}
inline void write(int address, MemoryUnit* data)
{
checkAddress(address);
delete map[address];
map[address] = data;
}
inline void writeByte(int address, int data)
{
checkAddress(address);
map[address]->setValue(data);
}
}
memory.h içerir. Aşağıdaki kodda yanlış bir şey mi var?
