main()

int encoder::main

(

const std::vector< std::string > &

args

)

Main method of the program, should you choose to run it as a command line version.

Parameters

args	The command line arguments, with args[0] being the program name.

printUsage()

void encoder::printUsage

(

const std::string &

programName

)

Prints the usage of the command line version.

Parameters

programName

The name of the program.

encodeFile()

void encoder::encodeFile	(	const std::string &	inputName,
		const std::string &	outputName,
		const std::string &	treeName
	)

Encodes a file using Huffman coding.

Also creates the compressed output of the HuffmanTree so it can be read in and used for decompression.

Parameters

inputName	Name of the file to be compressed.
outputName	Name of the file to write compressed output.
treeName	Name of the file to write the compressed HuffmanTree.

getFrequencies()

vector< Frequency > encoder::getFrequencies

(

const std::string &

str

)

Determines the frequencies of characters in a string.

Parameters

str	The string to be searched.

Returns

A vector of Frequency objects representing the frequency each character in the file has.
