Extension Properties

isEmpty

val Input.isEmpty: Boolean

For streaming input it should be Input.endOfInput instead.

isNotEmpty

val Input.isNotEmpty: Boolean

For streaming input there is no reliable way to detect it without triggering bytes population from the underlying source. Consider using Input.endOfInput or use ByteReadPacket instead.

Extension Functions

asStream

fun Input.asStream(): InputStream

Convert io.ktor.utils.io Input to java InputStream

completeReadHead

fun Input.completeReadHead(current: IoBuffer): Unit
fun Input.completeReadHead(current: ChunkBuffer): Unit

copyTo

fun Input.copyTo(output: Output): Long

Copy all bytes to the output. Depending on actual input and output implementation it could be zero-copy or copy byte per byte. All regular types such as ByteReadPacket, BytePacketBuilder, AbstractInput and AbstractOutput are always optimized so no bytes will be copied.

discard

fun Input.discard(): Long

Discard all remaining bytes.

discardExact

fun Input.discardExact(n: Long): Unit
fun Input.discardExact(n: Int): Unit

Discard exactly n bytes or fail if not enough bytes in the input to be discarded.

discardUntilDelimiter

fun Input.discardUntilDelimiter(delimiter: Byte): Long

Discards bytes until delimiter occurred

discardUntilDelimiters

fun Input.discardUntilDelimiters(
    delimiter1: Byte,
    delimiter2: Byte
): Long

Discards bytes until of of the specified delimiters delimiter1 or delimiter2 occurred

forEach

fun Input.forEach(block: (Byte) -> Unit): Unit

For every byte from this input invokes block function giving it as parameter.

peekCharUtf8

fun Input.peekCharUtf8(): Char

peekTo

fun Input.peekTo(
    destination: IoBuffer,
    offset: Int = 0,
    min: Int = 1,
    max: Int = Int.MAX_VALUE
): Int
fun Input.peekTo(
    destination: Buffer,
    offset: Int = 0,
    min: Int = 1,
    max: Int = Int.MAX_VALUE
): Int

Copy at least min but up to max bytes to the specified destination buffer from this input skipping offset bytes. If there are not enough bytes available to provide min bytes then it simply return number of available bytes with no exception so the returned value need to be checked. It is safe to specify max > destination.writeRemaining but min shouldn’t be bigger than the destination free space. This function could trigger the underlying source reading that may lead to blocking I/O. It is safe to specify too big offset so in this case this function will always return 0. This function usually copy more bytes than min (unless max = min) but it is not guaranteed. When 0 is returned with offset = 0 then it makes sense to check Input.endOfInput.
