HexFormat
Builds a new HexFormat by configuring its format options using the specified builderAction, and returns the resulting format.
inline fun HexFormat(builderAction: HexFormat.Builder.() -> Unit): HexFormat(source)
import kotlin.text.HexFormat
fun main() {
// Create a HexFormat instance with custom settings using the inline builder
val formatter = HexFormat {
withSeparator('-') // add '-' between each byte
withPrefix("0x") // prepend "0x" to the output
withPadding('0', 4) // pad each byte to 4 characters with '0'
}
// Example byte array
val bytes = byteArrayOf(0x1A, 0x2B, 0x3C)
// Convert the byte array to a formatted hex string
val hexString = formatter.formatHex(bytes)
println(hexString) // prints: 0x1A-2B-3C
// Parse the hex string back into a byte array
val parsedBytes = formatter.parseHex(hexString)
println(parsedBytes.contentToString()) // prints: [26, 43, 60]
}
