write
Writes bytes from source array or its subrange to this sink.
Parameters
source
the array from which bytes will be written into this sink.
startIndex
the start index (inclusive) of the source subrange to be written, 0 by default.
Throws
when startIndex or endIndex is out of range of source array indices.
when startIndex > endIndex.
when the sink is closed.
Samples
import kotlinx.io.*
import kotlin.test.*
fun main() {
//sampleStart
val sink = Buffer()
sink.write(byteArrayOf(1, 2, 3, 4))
assertContentEquals(byteArrayOf(1, 2, 3, 4), sink.readByteArray())
sink.write(byteArrayOf(1, 2, 3, 4), startIndex = 1, endIndex = 3)
assertContentEquals(byteArrayOf(2, 3), sink.readByteArray())
//sampleEnd
}Removes byteCount bytes from source and write them to this sink.
If source will be exhausted before reading byteCount from it then an exception throws on an attempt to read remaining bytes will be propagated to a caller of this method.
Parameters
source
the source to consume data from.
byteCount
the number of bytes to read from source and to write into this sink.
Throws
Samples
import kotlinx.io.*
import kotlin.test.*
fun main() {
//sampleStart
val sink = Buffer()
val source = Buffer().also { it.writeInt(0x01020304) }
sink.write(source, 3)
assertContentEquals(byteArrayOf(1, 2, 3), sink.readByteArray())
assertContentEquals(byteArrayOf(4), source.readByteArray())
//sampleEnd
