readByteArray
Removes all bytes from this source and returns them as a byte array.
Throws
when the source is closed.
Samples
import kotlinx.io.*
import kotlin.test.*
fun main() {
//sampleStart
val buffer = Buffer()
buffer.write(byteArrayOf(1, 2, 3, 4, 5, 6, 7))
val out = ByteArray(10)
buffer.readTo(out, startIndex = 1, endIndex = 4)
assertContentEquals(byteArrayOf(0, 1, 2, 3, 0, 0, 0, 0, 0, 0), out)
assertContentEquals(byteArrayOf(4, 5, 6, 7), buffer.readByteArray())
//sampleEnd
}
Removes byteCount bytes from this source and returns them as a byte array.
Parameters
byteCount
the number of bytes that should be read from the source.
Throws
when byteCount is negative.
when the underlying source is exhausted before byteCount bytes of data could be read.
when the source is closed.
