Description

Methods

Public function NextToken: TToken;

NextToken moves to next token (updating fields Token, and eventually TokenFloat, TokenString and TokenFunctionClass) and returns the value of field Token.

When Token is tokEnd, then NextToken doesn't do anything, i.e. Token will remain tokEnd forever.

Exceptions raised
ECasScriptLexerError

Public function TokenDescription: string;

if current Token doesn't match required Tok.
