Answer 1

with Java Binary Block Parser the script to parse the message will be

    @Bin int field1;
    @Bin (type = BinType.BIT) boolean field2;
    @Bin(type = BinType.BIT) boolean field3;
    @Bin int field4;
    @Bin(type = BinType.BIT) int enums;
    @Bin(type = BinType.UBYTE_ARRAY) String str;
  }

  Parsed parsed = JBBPParser.prepare("int field1; bit field2; bit field3; int field4; bit:4 enums; ubyte [32] str;").parse(STREAM).mapTo(Parsed.class);
