ByteOrdering

There are two byte ordering modes known in the modern digital world

• Big-endian - the most significant byte of a word is stored in the smallest address, it is the default mode for Java and it is used in JBBP by default
• Little-endian - the least significant byte is stored in the smallest address

JBBP supports both the modes for parsing and packing

#Parsing It is impossible to define the byte ordering mode for all parsing fields because JBBP uses the big-endian mode by default for parsing, but it is possible to define a byte ordering mode per a field with the special modifier < (little-endian) or > (big-endian) which should be placed before the field type (but it doesn't work for structures, only for primitive types and primitive type arrays!) JBBPParser.prepare("<byte littleEndianField; byte bigEndianField;"); in the example above, the littleEndianField will be parsed in the little endian byte order but the bigEndianField will be parsed in the default big-endian order.

#Packing In opposite of parsing, you can define the byte order for all operations of packing JBBPOut.BeginBin(JBBPByteOrder.LITTLE_ENDIAN).Int(0,0).Short(21,96).Int(512).End().toByteArray(); but also it is possible to change the byte order during packing with the ByteOrder?() command, it makes effect for all next multi-byte commands of the packing object JBBPOut.BeginBin().ByteOrder(JBBPByteOrder.BIG_ENDIAN).Int(512).ByteOrder(JBBPByteOrder.LITTLE_ENDIAN).Int(512).End().toByteArray();
