Detailed Description

Definition of a class to find all the common words across multiple files

Constructor & Destructor Documentation

CommonWords::CommonWords ( const std::vector< std::string > & filenames )

Constructs a CommonWords object from a vector of filenames.

Parameters

filenames The list of filenames to read.

vector< string > CommonWords::file_to_vector ( const string & filename ) const

private

Takes a filename and transforms it to a vector of all words in that file.

Parameters

filename The name of the file that will fill the vector

vector< string > CommonWords::get_common_words ( unsigned int n ) const

Parameters

n	The number of times to word has to appear.

Returns: A vector of strings. The vector contains all words that appear in each file >= n times.

void CommonWords::init_common ( )

private

Initializes common.

void CommonWords::init_file_word_maps ( const vector< string > & filenames )

private

Parameters

filenames The vector of names of the files that will be used

std::map<std::string, unsigned int> CommonWords::common

private

common maps a word to the number of documents that word appears in

vector<map<string, unsigned int> > CommonWords::file_word_maps

private

file_word_maps holds a map for each file.

Each map associates a word in that file to the number of times it has been seen in that file.
