In Kotlin, the .encodeToHexString()
method is a part of the kotlinx.serialization
library and is used to encode the given data to a hexadecimal string. In this operation, it first serializes and converts the given data to a byte array, then delegates it to BinaryFormat
and finally encodes the resultant bytes to a hexadecimal string.
Syntax
fun <T> BinaryFormat.encodeToHexString(value: T): String
<T>
: The data type to be encoded.BinaryFormat
: The interface to which the byte array is to be delegated.value
: The data to be encoded.String
: The data type to be returned.
Example
In the following example, the .encodeToHexString()
method encodes the Codecademy
string to a hexadecimal string:
import kotlinx.serialization.*import kotlinx.serialization.protobuf.ProtoBuf@Serializabledata class Institution(val name: String)fun main() {val institution = Institution("Codecademy")val institutionToHexString = ProtoBuf.encodeToHexString(institution)println("Codecademy in Hex String: $institutionToHexString")}
The output for the above code is as follows:
Codecademy in Hex String: 0a0a436f6465636164656d79
