Constructor Detail

SASLAuthOperationImpl

public SASLAuthOperationImpl(String[] m,
                             String s,
                             Map<String,?> p,

                             OperationCallback c)

Method Detail

buildResponse

protected byte[] buildResponse(SaslClient sc)
                        throws SaslException

Specified by:

buildResponse in class SASLBaseOperationImpl

Throws:

SaslException

resetInput

protected void resetInput()

readFromBuffer

public void readFromBuffer(ByteBuffer b)
                    throws IOException

Description copied from interface: Operation

Read data from the given byte buffer and dispatch to the appropriate read mechanism.

Specified by:

readFromBuffer in interface Operation

Specified by:

readFromBuffer in class BaseOperationImpl

Throws:

IOException

getStatusForErrorCode

protected OperationStatus getStatusForErrorCode(int errCode,
                                                byte[] errPl)

Get the OperationStatus object for the given error code.

Parameters:

errCode - the error code

Returns:

the status to return, or null if this is an exceptional case

opaqueIsValid

protected boolean opaqueIsValid()

Validate an opaque value from the header. This may be overridden from a subclass where the opaque isn't expected to always be the same as the request opaque.

prepareBuffer

protected void prepareBuffer(String key,
                             long cas,
                             byte[] val,
                             Object... extraHeaders)

Prepare a send buffer.

Parameters:

key - the key (for keyed ops)

cas - the cas value

val - the data payload

extraHeaders - any additional headers that need to be sent
