示例1: buildFromSnapshot

public static ParserInterpreterData buildFromSnapshot(DocumentSnapshot snapshot) {
LexerInterpreterData lexerInterpreterData = LexerInterpreterData.buildFromSnapshot(snapshot);
if (lexerInterpreterData == null) {
return null;
}
List<SyntaxError> syntaxErrors = new ArrayList<>();
Tool tool = new CustomTool(snapshot);
tool.errMgr = new CustomErrorManager(tool);
tool.addListener(new ErrorListener(snapshot, tool, syntaxErrors));
tool.libDirectory = new File(snapshot.getVersionedDocument().getFileObject().getPath()).getParent();
ANTLRStringStream stream = new ANTLRStringStream(snapshot.getText());
stream.name = snapshot.getVersionedDocument().getFileObject().getNameExt();
GrammarRootAST ast = tool.parse(stream.name, stream);
Grammar grammar = tool.createGrammar(ast);
if (grammar instanceof LexerGrammar) {
return null;
}

ParserInterpreterData data = new ParserInterpreterData();
// start by filling in the lexer data
data.lexerInterpreterData = lexerInterpreterData;
// then fill in the parser data
