Brain

• new Brain(options: Options)
• Brain#getSentence(word: String, callback?: (error: Error, sentence: String)): Promise<String>
• Brain#addSentence(sentence: String, callback?: (error: Error, success: boolean)): Promise<Boolean>

Options

• validCharacters: a list of valid characters that constitute words. changing this will make other languages parseable
• provider: a provider instance. check the built in MemoryProvider for an example

Quad

• new Quad(o1, o2, o3, o4)
• Quad#o1, Quad#o2, Quad#o3, Quad#o4
• Quad#canEnd, Quad#canStart

Providers

MemoryProvider

• new MemoryProvider()
• memoryProvider.toJSON()
• memoryProvider.fromJSON(json: String)

FileSystemProvider

• new FileSystemProvider(directory: String)
• fileSystemProvider.initialize(): Promise
