### Constructor
```cpp
Stream();
Stream(const Stream &stream);
Stream(const std::vector &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
```cpp
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
```cpp
Stream operator = (const Stream &stream);
```
#### Parameters
* `stream:` The source stream
### operator\[]
This operator return the value at the position `n` of the buffer
```cpp
unsigned char operator[](size_t n);
```
### getBuffer
This method return the buffer that contain the binary data
```cpp
const std::vector &getBuffer() const;
```
### size
This method return the size of the binary data in bytes
```cpp
size_t size() const;
```
### clear
This method clear the binary data
```cpp
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.
```cpp
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
```cpp
unsigned int getDataUInt();
unsigned short getDataUShort();
unsigned char getDataUChar();
int getDataInt();
short getDataShort();
char getDataChar();
```
