Method Details

readComplete0

protected void readComplete0(byte op,
 int res,
 int flags,
 short data,
 int outstanding)

Description copied from class: AbstractIoUringChannel.AbstractUringUnsafe

Called once a read was completed.

Specified by:

readComplete0 in class AbstractIoUringChannel.AbstractUringUnsafe

scheduleRead0

protected int scheduleRead0(boolean first,
 boolean socketIsEmpty)

Description copied from class: AbstractIoUringChannel.AbstractUringUnsafe

Schedule a read and returns the number of AbstractIoUringChannel.AbstractUringUnsafe.readComplete(byte, int, int, short) calls that are expected because of the scheduled read.

Specified by:

scheduleRead0 in class AbstractIoUringChannel.AbstractUringUnsafe

Parameters:

first - true if this is the first read of a read loop.

socketIsEmpty - true if the socket is guaranteed to be empty, false otherwise.

Returns:

the number of AbstractIoUringChannel.AbstractUringUnsafe.readComplete(byte, int, int, short) calls expected or -1 if AbstractIoUringChannel.AbstractUringUnsafe.readComplete(byte, int, int, short) is called until the read is cancelled (multi-shot).

scheduleRecvmsg

private int scheduleRecvmsg(ByteBuf byteBuf,
 int numDatagram,
 int datagramSize)

scheduleRecvmsg0

private boolean scheduleRecvmsg0(long bufferAddress,
 int bufferLength,
 boolean first,
 boolean more)

writeComplete0

boolean writeComplete0(byte op,
 int res,
 int flags,
 long data,
 int outstanding)

Description copied from class: AbstractIoUringChannel.AbstractUringUnsafe

Called once a write was completed.

Specified by:

writeComplete0 in class AbstractIoUringChannel.AbstractUringUnsafe

Parameters:

op - the op code

res - the result.

flags - the flags.

data - the data that was passed when submitting the op.

outstanding - the outstanding write completions.

removeFromOutboundBuffer

private boolean removeFromOutboundBuffer(ChannelOutboundBuffer outboundBuffer,
 int res,
 java.lang.String errormsg)

connectComplete

void connectComplete(byte op,
 int res,
