(Swift 2) Append Big-Endian or Little-Endian IntegersDemonstrates how to append integers in big-endian or little-endian byte order to a BinData. Note: This example requires Chilkat v9.5.0.77 or greater.
func chilkatTest() { let bd = CkoBinData() // The hex value of decimal 123456789 is 0x075BCD15 var x: Int = 123456789 // Appending little-endian causes bytes to be // appended in the order 0x15, 0xCD, 0x5B, 0x07 var littleEndian: Bool = true var success: Bool = bd.AppendInt4(x, littleEndian: littleEndian) print("\(bd.GetEncoded("hex"))") // Output is: 15CD5B07 // Now append the same integer in big-endian byte order. // Appending bit-endian causes bytes to be // appended in the order 0x07, 0x5B, 0xCD, 0x15 littleEndian = false bd.AppendInt4(x, littleEndian: littleEndian) print("\(bd.GetEncoded("hex"))") // bd now contains: 15CD5B07075BCD15 // ------------------------------------------- // Now do the same thing with 16-bit integers bd.Clear() // 1234 decimal = 0x04D2 hex. x = 1234 littleEndian = true bd.AppendInt2(x, littleEndian: littleEndian) print("\(bd.GetEncoded("hex"))") // Output is: D204 littleEndian = false bd.AppendInt2(x, littleEndian: littleEndian) print("\(bd.GetEncoded("hex"))") // Output is now: D20404D2 } |
