## Public Member Functions

void | EncodeArray (unsigned char *input, size_t sizeInBytes, RakNet::BitStream *output)
| Pass an array of bytes to array and a preallocated BitStream to receive the output.
void | GenerateFromFrequencyTable (unsigned int frequencyTable[256])
| Given a frequency table of 256 elements, all with a frequency of 1 or more, generate the tree.
void | FreeMemory (void)
| Free the memory used by the tree.

## Detailed Description

This generates special cases of the huffman encoding tree using 8 bit keys with the additional condition that unused combinations of 8 bits are treated as a frequency of 1.

## Member Function Documentation

void HuffmanEncodingTree::EncodeArray | ( | unsigned char * | input,
|  | size_t | sizeInBytes,
|  | RakNet::BitStream * | output |
| ) |  |  |

Pass an array of bytes to array and a preallocated BitStream to receive the output.

Parameters:

  `[in]` | input | Array of bytes to encode
  `[in]` | sizeInBytes | size of input
  `[out]` | output | The bitstream to write to
