Class ActionLexer

Implemented Interfaces:
ActionLexerTokenTypes, TokenStream
public class ActionLexer
extends CharScanner
implements ActionLexerTokenTypes, TokenStream
Perform the following translations: AST related translations ## -> currentRule_AST #(x,y,z) -> codeGenerator.getASTCreateString(vector-of(x,y,z)) #[x] -> codeGenerator.getASTCreateString(x) #x -> codeGenerator.mapTreeId(x) Inside context of #(...), you can ref (x,y,z), [x], and x as shortcuts. Text related translations $append(x) -> text.append(x) $setText(x) -> text.setLength(_begin); text.append(x) $getText -> new String(text.getBuffer(),_begin,text.length()-_begin) $setToken(x) -> _token = x $setType(x) -> _ttype = x $FOLLOW(r) -> FOLLOW set name for rule r (optional arg) $FIRST(r) -> FIRST set name for rule r (optional arg)
