Method Details

update

void update(int res,
 int flags,
 byte opcode,
 long userData,
 ByteBuffer extraCqeData)

res

public int res()

Returns the result.

Returns:

the result

flags

public int flags()

Returns the flags.

Returns:

flags

opcode

public byte opcode()

Returns the op code of the IoUringIoOps.

Returns:

opcode

data

@Deprecated
public short data()

Deprecated.

use userData() instead.

Returns the data that is passed as part of IoUringIoOps.

Returns:

data.

userData

public long userData()

Returns the user data that was passed as part of the submission.

Returns:

user data.

extraCqeData

public ByteBuffer extraCqeData()

Returns the extra data for the CQE. This will only be non-null of the ring was setup with IORING_SETUP_CQE32. As this ByteBuffer maps into the shared completion queue its important to not hold any reference to it outside of the IoHandle.handle(IoRegistration, IoEvent) method.

Returns:

extra data for the CQE or null.

toString

public String toString()

Overrides:
