Class TokenScanner

java.lang.Object

gherkin.TokenScanner

All Implemented Interfaces:

Parser.ITokenScanner

public class TokenScanner
extends Object
implements Parser.ITokenScanner

The scanner reads a gherkin doc (typically read from a .feature file) and creates a token for each line. The tokens are passed to the parser, which outputs an AST (Abstract Syntax Tree).

If the scanner sees a # language header, it will reconfigure itself dynamically to look for Gherkin keywords for the associated language. The keywords are defined in gherkin-languages.json.
