Interface Lexer

All Known Implementing Classes:

Lexer.DefaultLexer

public interface Lexer

Interface to tokenize arguments into tokens. Generic language parser usually contains lexing and parsing where this Lexer represents the former lexing side. Lexing takes a first step to analyse basic construct of elements out from given arguments. We get rough idea what each argument represents but don't look deeper if any of it is correct which happens later when tokens go through parsing operation.
