        throw new ScannerException("Could not parse string \"" + string + "\": " + e.getMessage());
    }
    if (r1 == null) {

        throw new ScannerException("unexpected token format");
    }
    throw new ScannerException("Could not parse string \"" + string + "\": " + t1.toString());
}

Example 2 with ScannerException

use of org.erlide.engine.services.parsing.ScannerException in project erlide_eclipse by erlang.

the class ErlangBracketInserter method getKindOfBracket.
