Init

HRESULT Init()

Производит инициализацию данных объекта, для объектов - сплитеров или ридеров производит открытие файлов и начальный парсинг.

Close

HRESULT Close()

Освобождает ресурсы используемые объектом, закрывает файлы, освобождает блоки памяти.

BeginFlush

HRESULT BeginFlush()

EndFlush

HRESULT EndFlush()

Convert

HRESULT Convert(
    [in] BYTE* pbSrc,
    [in] int cbSrc,
    [in] BYTE* pbDst,
    [in] int cbDst,
    [out] int* pcbActual,
    [in] int nReserved,
    [in] BYTE* pbReserved
    );

Method for synchronous conversions. If this method is implemented then methods for asynchronous conversions (CanPutFrame(), PutFrame(), CanGetFrame(), GetFrame()) can be not implemented.

Parameters:
pbSrc Source buffer for conversion.
cbSrc Size of data in source buffer in bytes.
pbDst Destination buffer for result of conversion.
cbDst Size of destination buffer in bytes
pcbActual Size of returned data in destination buffer in bytes
nReserved Library specific variable (see library description)
pbReserved Library specific variable (see library description)
