Unigine::BitStream Class

Header: #include <UnigineMathLibCommon.h>

This class represents an auxiliary structure for the fixed-size buffer and it's bitwise read/write operations. You can specify the size for the structure (template class). The default size is 128 bits.

BitStream Class

Members


static BitStreamPtr create ( ) #

Constructor. Initializes the bit buffer.

const unsigned char * get ( ) const#

Returns the pointer to the constant bit buffer.

Return value

Pointer to the constant bit buffer.

unsigned char * get ( ) #

Returns the pointer to the bit buffer.

Return value

Pointer to the bit buffer.

int size ( ) const#

Returns the size of the structure in bytes.

Return value

Size of the structure in bytes.

void clear ( ) #

Clears the buffer.

void align ( ) #

Aligns the buffer.

int readUBits ( int num ) #

Returns the unsigned data from the buffer.

Arguments

  • int num - Number of bits to return.
