Detailed Description

Auxiliary class to read or write a stream of bits to a memory location.

Call get() to read a bit and move the position one bit forward.

Constructor & Destructor Documentation

◆ Bit_reader() [1/2]

Bit_reader::Bit_reader ( const char *  ptr = nullptr)
inline

◆ Bit_reader() [2/2]

inline

Member Function Documentation

◆ get()

bool Bit_reader::get ( )
inline

Read the next bit and move the read position one bit forward.

Returns
true if the bit was 1, false if the bit was 0.
