ByteArrayBuilder

class ByteArrayBuilder(var data: ByteArray, size: Int = data.size, val allowGrow: Boolean = true)

Analogous to StringBuilder but for ByteArray. Allows to append values to end calling toByteArray. Provides some methods like s16LE or f32BE to append specific bit representations easily.

Constructors

ByteArrayBuilder

constructor(data: ByteArray, size: Int = data.size, allowGrow: Boolean = true)

constructor(initialCapacity: Int = 4096)

Properties

allowGrow
