Public Member Functions | |
Constructor, Destructor, and Initialization | |
constexpr | Base64InputStream () noexcept |
Instantiates the object with default parameters (default constructor). | |
errno_t | Init (CharOption char_option) noexcept |
Initializes the object. For information on the arguments, see Base64Decoder::CharOption . | |
errno_t | Init () noexcept |
Runs Init(Base64Decoder::kBase64Default) . | |
virtual | ~Base64InputStream () noexcept override |
Destructor. | |
![]() | |
errno_t | SetStream (InputStream *istr) noexcept |
Sets the input stream for reading the pre-converted data. More... | |
InputStream * | GetStream () const noexcept |
Gets the input stream for reading the pre-converted data. More... | |
![]() | |
errno_t | GetErrorValue () const noexcept |
Gets the error value. More... | |
size_t | Pos () const noexcept |
Returns the current position in the stream. More... | |
uint64_t | Pos64 () const noexcept |
Returns the current position in the stream as a 64-bit value. More... | |
bool | IsEos () noexcept |
Returns true if the stream is finished being read through to the end. If the stream has not been read through to the end, or if an error occurs, the function returns false . More... | |
int | Read () noexcept |
Reads one byte of data from the stream. More... | |
int | Peek () noexcept |
Reads the next byte without consuming the stream. More... | |
size_t | Skip (size_t nbytes) noexcept |
Skips over the number of bytes specified by nbytes. More... | |
size_t | Read (void *ptr, size_t nbytes) noexcept |
Reads the number of bytes of data specified by nbytes into the memory region specified by ptr. More... | |
template<size_t N> | |
size_t | Read (nlib_byte_t(&buf)[N]) noexcept |
A template overload of the above function. | |
bool | Close () noexcept |
Closes the stream. Returns true if successful. More... | |
bool | Mark (size_t readlimit) noexcept |
This function provides settings that allow you to return to the current load position using GoBackToMark() . More... | |
bool | GoBackToMark () noexcept |
This function allows you to return to the load position that the last Mark() has been executed at. More... | |
bool | IsMarkSupported () const noexcept |
This function returns true if this stream supports Mark() and GoBackToMark() . | |
operator bool () const | |
Returns true if the object has been initialized and an error has not occurred inside, or returns false if an error has occurred inside. | |
constexpr | InputStream () noexcept |
Instantiates the object with default parameters (default constructor). This function is called from the derived class. | |
virtual | ~InputStream () noexcept |
Destructor. This function is called from the derived class. | |
Additional Inherited Members | |
![]() | |
void | SetBuffer (void *p, size_t nbytes, bool is_mark_supported, bool is_buf_readonly) noexcept |
Sets the buffer held by InputStream . More... | |
void | SetError (errno_t e) const noexcept |
Sets an error to InputStream . More... | |
The class for reading Base64
-encoded data.
InputConverterStream
is held in the base class. When operating as InputStream
, the read data is Base64
-decoded and returned. The InputConverterStream::SetStream
function sets a stream for reading Base64
strings, and then the stream is used. EILSEQ
). EILSEQ
error is also generated if there are not enough '=' padding characters. Definition at line 24 of file Base64InputStream.h.
