Append Big-Endian or Little-Endian Integers

Demonstrates 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.

JavaScript

var success = false;

var bd = new CkBinData();

// The hex value of decimal 123456789 is 0x075BCD15
var x = 123456789;

// Appending little-endian causes bytes to be
// appended in the order 0x15, 0xCD, 0x5B, 0x07
var littleEndian = true;
success = bd.AppendInt4(x,littleEndian);

console.log(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);

console.log(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);

console.log(bd.GetEncoded("hex"));
// Output is: D204

littleEndian = false;
bd.AppendInt2(x,littleEndian);

console.log(bd.GetEncoded("hex"));
// Output is now: D20404D2
