Demonstrate Binary Data Encoding Methods

Demonstrates binary data encoding methods.

Note: This example requires Chilkat v9.5.0.64 or later.

Go

    binData := chilkat.NewBinData()

    // Append 10 bytes: 00, 01, 02, 03, 04, 05, 06, 07, 08, 09
    binData.AppendEncoded("00010203040506070809","hex")

    // Show that binData contains 10 bytes.
    fmt.Println("num bytes = ", binData.NumBytes())

    // Get as base64
    fmt.Println("base64: ", *binData.GetEncoded("base64"))

    // Get a chunk of the binary data.
    // The 1st byte is at index 0.
    // The output should be "02030405"
    offset := 2
    numBytes := 4
    fmt.Println("chunk: ", *binData.GetEncodedChunk(offset,numBytes,"hex"))

    // Copy the bytes to a StringBuilder using the base64url encoding
    sb := chilkat.NewStringBuilder()
    binData.GetEncodedSb("base64url",sb)
    fmt.Println("base64url: ", *sb.GetAsString())

    // Remove a chunk from the binary data
    offset = 2
    numBytes = 4
    binData.RemoveChunk(offset,numBytes)
    // The bytes remaining are 00,01,06,07,08,and 09
    fmt.Println("after removing chunk: ", *binData.GetEncoded("hex"))

    binData.DisposeBinData()
    sb.DisposeStringBuilder()
