The New version of JBBP 1.1.0 is out and accessible in the maven central, now it supports not only parsing of binary data and mapping them to classes but also and back operation - packing binary data blocks from mapped classes and even printing of mapped class description, take a look at example
class Flags {
@Bin(outOrder = 1, name = "f1", type = BinType.BIT, outBitNumber = JBBPBitNumber.BITS_1, comment = "It's flag one") byte flag1;
@Bin(outOrder = 2, name = "f2", type = BinType.BIT, outBitNumber = JBBPBitNumber.BITS_2, comment = "It's second flag") byte flag2;
@Bin(outOrder = 3, name = "f3", type = BinType.BIT, outBitNumber = JBBPBitNumber.BITS_1, comment = "It's 3th flag") byte flag3;
@Bin(outOrder = 4, name = "f4", type = BinType.BIT, outBitNumber = JBBPBitNumber.BITS_4, comment = "It's 4th flag") byte flag4;
}
final int data = 0b10101010;
Flags parsed = JBBPParser.prepare("bit:1 f1; bit:2 f2; bit:1 f3; bit:4 f4;", JBBPBitOrder.MSB0).parse(new byte[]{(byte)data}).mapTo(Flags.class);
System.out.println(new JBBPTextWriter().Bin(parsed).Close().toString());
assertEquals(data, JBBPOut.BeginBin(JBBPBitOrder.MSB0).Bin(parsed).End().toByteArray()[0] & 0xFF);
the code will parse the byte, then print its values
;--------------------------------------------------------------------------------
; START : Flags
;--------------------------------------------------------------------------------
01; f1, It's flag one
02; f2, It's second flag
00; f3, It's 3th flag
05; f4, It's 4th flag
;--------------------------------------------------------------------------------
; END : Flags
;--------------------------------------------------------------------------------
and again will pack parsed data into byte
