Public Methods

Encoder

inline

inline Encoder(int buffersize)

Parameters

• buffersize Internal read buffer size in bytes.

encode

inline

inline void encode(std::istream & istrm, std::ostream & ostrm)

Encodes the entire input stream and writes Base64 output to ostrm. Resets the encoder state after completion.

Parameters

• istrm Source stream to encode.

• ostrm Destination stream for Base64 output.

encode

inline

inline void encode(const std::string & in, std::string & out)

Encodes a string to Base64 and appends the result to out. Resets the encoder state after completion.

Parameters

• in Input string.

• out Output string to which Base64 characters are appended.

encode

virtual inline

virtual inline ssize_t encode(const char * inbuf, size_t nread, char * outbuf)

Encodes a raw buffer, writing Base64 characters to outbuf. May be called multiple times before calling [finalize()](#finalize-4).

Parameters

• inbuf Input binary data.

• nread Number of bytes to encode.

• outbuf Output buffer; must be at least nread * 4 / 3 + 4 bytes.

Returns

Number of Base64 characters written.

finalize

virtual inline

virtual inline ssize_t finalize(char * outbuf)

Writes any pending padding and resets the encoder state. Must be called once after all [encode()](#encode-17) calls to flush the final block.

Parameters

• outbuf Output buffer; must be at least 5 bytes.

Returns

Number of characters written.

setLineLength

inline

inline void setLineLength(int lineLength)

Sets the line wrap length for encoded output (0 disables line wrapping).

Parameters

• lineLength Characters per line; use 0 to disable.
