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.

Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkBinData bd = new CkBinData();

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

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

    System.out.println(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);

    System.out.println(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);

    System.out.println(bd.getEncoded("hex"));
    //  Output is: D204

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

    System.out.println(bd.getEncoded("hex"));
    //  Output is now: D20404D2
