Public Member Functions | |
HuffmanEncodingTreeFactory () | |
Default constructor. | |
void | Reset (void) |
Reset the frequency table. You don't need to call this unless you want to reuse the class for a new tree. | |
void | AddToFrequencyTable (unsigned char *array, int size) |
void | GetFrequencyTable (unsigned int _frequency[256]) |
unsigned int * | GetFrequencyTable (void) |
HuffmanEncodingTree * | GenerateTree (void) |
This class takes a frequency table and given that frequence table, will generate an instance of HuffmanEncodingTree
void HuffmanEncodingTreeFactory::AddToFrequencyTable | ( | unsigned char * | array, | |
int | size | |||
) |
Pass an array of bytes to this to add those elements to the frequency table
[in] | array | the data to insert into the frequency table |
[in] | size | the size of the data to insert |
HuffmanEncodingTree* HuffmanEncodingTreeFactory::GenerateTree | ( | void | ) |
Generate a HuffmanEncodingTree. You can also use GetFrequencyTable and GenerateFromFrequencyTable in the tree itself
unsigned int* HuffmanEncodingTreeFactory::GetFrequencyTable | ( | void | ) |
Returns the frequency table as a pointer
void HuffmanEncodingTreeFactory::GetFrequencyTable | ( | unsigned int | _frequency[256] | ) |
Copies the frequency table to the array passed Retrieve the frequency table
[in] | _frequency | The frequency table used currently |
