Base Bytes

This library provides utilities for working with ByteArrays: hexadecimal conversion, building byte arrays from primitive values, bitwise helpers and the MedFloat IEEE 11073 medical float types.

Installing

This library is available on Maven Central. You can import Kaluga Base Bytes as follows:

repositories {
    // ...
    mavenCentral()
}
// ...
dependencies {
    // ...
    implementation("com.splendo.kaluga.base:bytes:$kalugaVersion")
}

Hex Conversion

• Convert a ByteArray to a hexadecimal String using toHexString(). An optional separator can be inserted between bytes.
• Parse a hexadecimal String back into a ByteArray using decodeHex().
• Construct a ByteArray from a list of Int values using bytesOf(...).

ByteArrayBuilder

ByteArrayBuilder accumulates primitive values into a ByteArray. Values of every primitive type (Byte, Short, Int, Long, Float, Double and their unsigned variants, as well as Int24/UInt24 and MedFloat) can be added, each encoded according to a configurable ByteOrder.

MedFloat

MedFloat16 and MedFloat32 represent the IEEE 11073 medical float formats commonly used in Bluetooth and health protocols. They wrap a Double and can be encoded to and decoded from their byte representations.

Bitwise Utilities

Extensions such as shl, shr, isBitSet and setBit are available for Byte, ByteArray and the unsigned integer types.

Data Converters

• Convert a ByteArray to a hexadecimal String using toHexString().
