Constructor & Destructor Documentation

OutputStreamWriter() [1/2]

OutputStreamWriter::OutputStreamWriter	(	OutputStream &__noclose__	_output,
		CharsetEncoder &	_encoder )

참조된 스트림과 엔코더로 객체를 구성한다. _output과 _encoder는 객체의 생면주기동안 유효해야 하며, _output은 close()에서 close하지 않는다.

Parameters

_output	A OutputStream
_decoder	A CharsetEncoder

OutputStreamWriter() [2/2]

OutputStreamWriter::OutputStreamWriter	(	OutputStream *__destroy__	_pOutput,
		CharsetEncoder *__destroy__	_pEncoder = NULL )

넘겨받은 스트림과 디코더로 객체를 구성한다. close()에서 _pOutput의 close()가 호출되고 _pOutput과 _pEncoder는 파괴된다.

Parameters

_pOutput	A OutputStream
_pEncoder	NULL이면 LocaleEncoder를 사용한다.

~OutputStreamWriter()

OutputStreamWriter::~OutputStreamWriter ( )

virtual

객체의 파괴를 수행한다. close하지 않았으면 close()하며 예외가 발생하면 무시한다.

Definition at line 74 of file OutputStreamWriter.cpp.

{
    if (__output)
    {
        try
        {
            close();
        }
        catch (Exception* cause)
        {
            __DCL_TRACE1(__T("%ls\n"), cause->toString().data());
            cause->destroy();
        }
    }
}

Member Function Documentation

close()

void OutputStreamWriter::close ( )

virtual

객체를 닫는다. 넘겨받은 OutputStream과 CharsetEncoder는 파괴된다.

Definition at line 90 of file OutputStreamWriter.cpp.

{
    __DCL_ASSERT_HANDLE(__output != NULL);
 
    Exception* e = NULL;
    OutputStream* output = __output;
    CharsetEncoder* encoder = __encoder;
    __output = NULL;
    __encoder = NULL;
 
    if (__closeDestroy)
    {
        if (encoder)
            encoder->destroy();
 
        try
        {
            output->close();
        }
        catch (Exception* cause)
        {
            e = cause;
        }
        output->destroy();
    }
 
    if (e)
        throw e;
}

flush()

void OutputStreamWriter::flush ( )

virtual

사용하고 있는 OutputStream의 flush를 호출한다.

Reimplemented from Writer.

Definition at line 121 of file OutputStreamWriter.cpp.

{
    __DCL_ASSERT_HANDLE(__output != NULL);
 
    __output->flush();
}

toString()

virtual String OutputStreamWriter::toString ( ) const

virtual

파생클래스를 위한 생성자이다. 객체의 구성에 대하여 간략한 요약을 리턴한다.

Reimplemented from Object.

write()

Writer & OutputStreamWriter::write ( const wchar_t * _buf, size_t _n )

virtual

텍스트를 출력한다.

Parameters

_buf	버퍼
_n	버퍼의 크기가 _n개의 wchar_t 문자

Returns

Writer&

Implements Writer.

Definition at line 129 of file OutputStreamWriter.cpp.

{
    __DCL_ASSERT_HANDLE(__output != NULL);
    __DCL_ASSERT_PARAM(_buf != NULL);
 
    __DCL_ASSERT(__encoder != NULL);
 
    const wchar_t* pCur = _buf;
    const wchar_t* pEnd = _buf + _n;
    byte_t aOutBuf[512];
    size_t nInCount;
 
    while ((nInCount = pEnd - pCur) > 0)
    {
        size_t nOutCount = __countof(aOutBuf, byte_t);
        int r = __encoder->encode(pCur, nInCount, aOutBuf, nOutCount);
        if (r != CS_NOERROR)
            throw (new IOException(toString(), new CharsetConvertException(r)));
        __output->write(aOutBuf, nOutCount);
        pCur += nInCount;
    }
 
    return *this;
}
