Detailed Description

Creates instances of the class HuffmanEncodingTree.

This class takes a frequency table and given that frequence table, will generate an instance of HuffmanEncodingTree

Constructor & Destructor Documentation

HuffmanEncodingTreeFactory::HuffmanEncodingTreeFactory ( )

Default constructor.

void HuffmanEncodingTreeFactory::AddToFrequencyTable	(	unsigned char *	array,
		int	size
	)

Pass an array of bytes to this to add those elements to the frequency table.

Parameters:

`[in]`	array	the data to insert into the frequency table
`[in]`	size	the size of the data to insert

HuffmanEncodingTree* HuffmanEncodingTreeFactory::GenerateTree ( void )

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.

Parameters:

[in] _frequency The frequency table used currently

void HuffmanEncodingTreeFactory::Reset ( void )

Reset the frequency table.

You don't need to call this unless you want to reuse the class for a new tree
