帮忙把这段c++代码翻译成java ,,谢啦

[zh2332926106]

头文件
ErrorCode.h

namespace hg{
namespace network{

class ErrorCode{
protected:
class Impl;

Impl* m_impl;
public:
ErrorCode();
virtual ~ErrorCode();

void assign(int value, const char* message);

int value(void) const;
const char* message(void) const;

operator bool() const;
bool operator!() const;
};

实现部分

ErrorCode.cpp

#include "ErrorCode.h"
#include <string>

namespace hg{
namespace network{

class ErrorCode::Impl{
protected:
int m_value;
std::string m_message;
public:
Impl();
virtual ~Impl();

void assign(int value, const char* message);

int value(void) const;
const char* message(void) const;
};

ErrorCode::Impl::Impl() : m_value(0)
{
}

ErrorCode::Impl::~Impl()
{
}

void ErrorCode::Impl::assign(int value, const char* message)
{
m_value = value;
m_message = message;
}

int ErrorCode::Impl::value(void) const
{
return m_value;
}

const char* ErrorCode::Impl::message(void) const
{
return m_message.c_str();
}

/****************************************************************************************/

ErrorCode::ErrorCode() : m_impl(new ErrorCode::Impl())
{
}

ErrorCode::~ErrorCode()
{
delete m_impl;
}

void ErrorCode::assign(int value, const char* message)
{
m_impl->assign(value, message);
}

int ErrorCode::value(void) const
{
return m_impl->value();
}

const char* ErrorCode::message(void) const
{
return m_impl->message();
}

ErrorCode::operator bool() const
{
return m_impl->value() == 0 ? false : true;
}

bool ErrorCode::operator!() const
{
return m_impl->value() == 0;
}

差不多是这样子

package hg.network;

public class ErrorCode
{
	private class Impl
	{
		private int m_value;
		private string m_message;
		public Impl()
		{
			m_value = 0;
		}
		
		public void assign(int value, string message)
		{
			m_value = value;
			m_message = message;
		}

		public int value(void)
		{
			return m_value;
		}
		
		public string message(void)
		{
			return m_message;
		}
	}

	private Impl m_impl;
	
	public ErrorCode()
	{
		m_impl = new Impl();
	}
	

	public void assign(int value, string message)
	{
		m_impl.assign(value, message);
	}

	public int value(void)
	{
		return m_impl.value();
	}
	
	public string message(void)
	{
		return m_impl.message();
	}
	

	public boolean is_valid()
	{
		return m_impl->value() == 0 ? false : true;
	}
}
