Member functions documentation

Constructor

Stream();
Stream(const Stream &stream);
Stream(const std::vector<unsigned char> &buffer);
Stream(const std::string &str);
Stream(const char str[], size_t size);

Parameters

  • stream: The Stream to copy

  • buffer: The buffer to copy

  • str: The string to put as buffer

  • size: The size of the string if needed

operator+=

This operator concat another binary data to the current object

void operator += (const Stream &stream);
void operator += (const unsigned char &data);
void operator += (const std::string &str);

Parameters

  • stream: The stream to concat

  • data: The single byte to concat

  • str: The string that contain binary data to concat

operator=

This operator change the buffer of the current object

Stream operator = (const Stream &stream);

Parameters

  • stream: The source stream

operator[]

This operator return the value at the position n of the buffer

unsigned char operator[](size_t n);

getBuffer

This method return the buffer that contain the binary data

const std::vector<unsigned char> &getBuffer() const;

size

This method return the size of the binary data in bytes

size_t size() const;

clear

This method clear the binary data

void clear();

subStream

This method return newly constructed Stream object with its value initialized to a copy of a substream of this object.

Stream subStream(size_t pos) const;
Stream subStream(size_t pos, size_t len) const;

Parameters

  • pos: Position of the first byte to put in the substream

  • len: The number of byte to includes in the substream

toString

This method return the stream in form of a std::string.

std::string toString() const;

setData

This bunch of methods concat binary data to the Stream object.

void setDataCharArray(const char *data, size_t size);
void setDataUInt(unsigned int data);
void setDataUShort(unsigned short data);
void setDataUChar(unsigned char data);
void setDataInt(int data);
void setDataShort(short data);
void setDataChar(char data);

Parameters

  • data: The varable you want to append in the Stream

  • size: The number of byte you want to append if needed

getData

This bunch of methods extract a binary data from the Stream object and return it

unsigned int getDataUInt();
unsigned short getDataUShort();
unsigned char getDataUChar();
int getDataInt();
short getDataShort();
char getDataChar();
