csvFileToTrainingData(String, int) - Static method in class TweetParser: Given a path to a CSV file and the column from which to extract the tweet data, computes a training set.

FileLineIterator - Class in <Unnamed>: FileLineIterator provides a useful wrapper around Java's provided BufferedReader and provides practice with implementing an Iterator.
FileLineIterator(String) - Constructor for class FileLineIterator: Creates a FileLineIterator for the file located at filePath.

generateTweet(int) - Method in class TwitterBot: Generates a tweet of a given length by using the populated MarkovChain.
generateTweets(int, int) - Method in class TwitterBot: Generates a series of tweets using generateTweet().
getPunctuation() - Static method in class TweetParser

hasNext() - Method in class FileLineIterator: Returns true if there are lines left to read in the file, and false otherwise.
hasNext() - Method in class MarkovChain: This method should check if there is another word to retrieve from the Markov Chain based on the current word of our walk.

isPunctuated(String) - Static method in class TwitterBot: A helper function to determine if a string ends in punctuation.

ListNumberGenerator - Class in <Unnamed>: Produces deterministic numbers by iterating repeatedly over a List or Integer[] argued in the constructors.
ListNumberGenerator(Integer[]) - Constructor for class ListNumberGenerator
ListNumberGenerator(List<Integer>) - Constructor for class ListNumberGenerator

main(String[]) - Static method in class TwitterBot: Prints ten generated tweets to the console so you can see how your bot is performing!
MarkovChain - Class in <Unnamed>: A Markov Chain is a data structure that tracks the frequency with which one value follows another value in sequence.
MarkovChain() - Constructor for class MarkovChain: No need to write any constructors.
MarkovChain(NumberGenerator) - Constructor for class MarkovChain: No need to write any constructors.

next() - Method in class FileLineIterator: Returns the next line from the file, or throws a NoSuchElementException if there are no more strings left to return (i.e.
next() - Method in class ListNumberGenerator
next() - Method in class MarkovChain: Returns either: (1) the most recent word passed to reset(word), or (2) a successor picked from the probability distribution associated with the word most recently returned by next()
next(int) - Method in class ListNumberGenerator
next(int) - Method in interface NumberGenerator
next(int) - Method in class RandomNumberGenerator
NumberGenerator - Interface in <Unnamed>: This simple interface produces numbers.

RandomNumberGenerator - Class in <Unnamed>: Produces random numbers using Java's Random class
RandomNumberGenerator() - Constructor for class RandomNumberGenerator
RandomNumberGenerator(long) - Constructor for class RandomNumberGenerator
randomPunctuation() - Method in class TwitterBot: A helper function for providing a random punctuation String.
reset() - Method in class MarkovChain: DO NOT EDIT THIS METHOD.
reset(String) - Method in class MarkovChain: Given a starting String, sets up the Iterator functionality such that: (1) the Markov Chain will begin a walk at start.

train(Iterator<String>) - Method in class MarkovChain: Adds a sentence's training data to the MarkovChain frequency information.
TweetParser - Class in <Unnamed>: TweetParser.csvFileToTrainingData() takes in a CSV file that contains tweets and iterates through the file, one tweet at a time, removing parts of the tweets that would be bad inputs to MarkovChain (for example, a URL).
TweetParser() - Constructor for class TweetParser
TwitterBot - Class in <Unnamed>: This is the class where everything you've worked on thus far comes together! You can see that we've provided a path to a CSV file full of tweets and the column from which they can be extracted.
TwitterBot(String, int) - Constructor for class TwitterBot: Given a column and a path to the csvFile, initializes the TwitterBot by training the MarkovChain with sentences sourced from that CSV file.
TwitterBot(String, int, NumberGenerator) - Constructor for class TwitterBot: Given a column and a path to the csvFile, initializes the TwitterBot by training the MarkovChain with all the sentences obtained as training data from that CSV file.

writeStringsToFile(List<String>, String, boolean) - Method in class TwitterBot: Given a List of Strings, prints those Strings to a file (one String per line in the file).
writeTweetsToFile(int, int, String, boolean) - Method in class TwitterBot: Generates tweets and writes them to a file.
