Huffman.hpp

HuffmanEncoder::space_left
uint8_t space_left
Indicates the remaining unused bits in the current buffer element.
Definition HuffmanEncoder.hpp:34

HuffmanEncoder::tree
const HuffmanTree * tree
Pointer to the Huffman tree used for encoding.
Definition HuffmanEncoder.hpp:44

HuffmanEncoder::HuffmanEncoder
HuffmanEncoder(const string &fn, const HuffmanTree *root)
Constructs a HuffmanEncoder with output file and tree reference.
Definition HuffmanEncoder.cpp:83

HuffmanEncoder::writeHeader
void writeHeader()
Writes the header of the encoded file, including code map sizes and padding info.
Definition HuffmanEncoder.cpp:5

HuffmanEncoder::writeEncodedString
void writeEncodedString()
Encodes the string using the Huffman tree and writes the resulting bitstream.
Definition HuffmanEncoder.cpp:50

HuffmanEncoder::insertToBuffer
void insertToBuffer(const bitset< 32 > &code)
Inserts a 32-bit code into the internal buffer, managing space and alignment.
Definition HuffmanEncoder.cpp:130

HuffmanEncoder::buffer
vector< u_int32_t > buffer
A buffer that stores 32-bit chunks of the encoded bitstream.
Definition HuffmanEncoder.hpp:29

HuffmanEncoder::writeMapToBinary
void writeMapToBinary()
Serializes the Huffman code maps (8b/16b/32b) to the output file in binary format.
Definition HuffmanEncoder.cpp:16

HuffmanEncoder::outFile
ofstream outFile
Output file stream to which encoded data is written.
Definition HuffmanEncoder.hpp:39

HuffmanEncoder::encodeToFile
void encodeToFile(const vector< uint8_t > str)
Encodes a byte vector and writes it to the output file.
Definition HuffmanEncoder.cpp:91

HuffmanTree
Constructs and manages a Huffman tree for encoding.
Definition Huffman.hpp:94
