Functions

Link copied to clipboard
open suspend override fun awaitContent(min: Int): Boolean

Suspend the channel until it has min bytes or gets closed. Throws exception if the channel was closed with an error. If there are bytes available in the channel, this function returns immediately.

suspend fun ByteReadChannel.copyTo(channel: ByteWriteChannel, limit: Long): Long
suspend fun ByteReadChannel.copyTo(channel: WritableByteChannel, limit: Long = Long.MAX_VALUE): Long

Copy up to limit bytes to blocking NIO channel. Copying to a non-blocking channel requires selection and not supported. It is suspended if no data are available in a byte channel but may block if destination NIO channel blocks.

suspend fun ByteReadChannel.copyTo(out: OutputStream, limit: Long = Long.MAX_VALUE): Long

Copies up to limit bytes from this byte channel to out stream suspending on read channel and blocking on output

suspend fun ByteReadChannel.discard(max: Long = Long.MAX_VALUE): Long

suspend fun ByteReadChannel.discardExact(value: Long)
Link copied to clipboard

Suspends the channel until it is exhausted or gets closed. If the read buffer is empty, it suspends until there are bytes available in the channel. Once the channel is exhausted or closed, this function returns.

inline suspend fun ByteReadChannel.read(crossinline block: suspend (ByteArray, Int, Int) -> Int): Int
inline suspend fun ByteReadChannel.read(min: Int = 1, noinline consumer: (ByteBuffer) -> Unit)

Invokes consumer when it will be possible to read at least min bytes providing byte buffer to it so lambda can read from the buffer up to ByteBuffer.remaining bytes. If there are no min bytes available then the invocation could suspend until the requirement will be met.

fun ByteReadChannel.readAvailable(min: Int, block: (Buffer) -> Int): Int

Invokes block if it is possible to read at least min byte providing buffer to it so lambda can read from the buffer up to Buffer.readRemaining bytes. If there are no min bytes available then the invocation returns -1.

suspend fun ByteReadChannel.readAvailable(buffer: ByteArray, offset: Int = 0, length: Int = buffer.size - offset): Int

Reads all available bytes to dst buffer and returns immediately or suspends if no bytes available

Reads bytes from the channel and writes them to the buffer up to its limit. If the channel's read buffer is exhausted, it suspends until there are bytes available.

Invokes block if it is possible to read at least min byte providing byte buffer to it so lambda can read from the buffer up to ByteBuffer.available bytes. If there are no min bytes available then the invocation returns 0.

suspend fun ByteReadChannel.readAvailable(dst: CPointer<ByteVar>, offset: Int, length: Int): Int

Reads all available bytes to dst buffer and returns immediately or suspends if no bytes available

suspend fun ByteReadChannel.readBuffer(): Buffer
suspend fun ByteReadChannel.readBuffer(max: Int): Buffer

Reads all length bytes to dst buffer or fails if channel has been closed. Suspends if not enough bytes available.

suspend fun ByteReadChannel.readUTF8LineTo(out: Appendable, max: Int = Int.MAX_VALUE): Boolean

Reads a line of UTF-8 characters to the specified out buffer. It recognizes CR, LF and CRLF as a line delimiter.

fun ByteReadChannel.toInputStream(parent: Job? = null): InputStream

Create blocking java.io.InputStream for this channel that does block every time the channel suspends at read Similar to do reading in runBlocking however you can pass it to regular blocking API
