Method Detail

buildResponse

protected byte[] buildResponse(javax.security.sasl.SaslClient sc)
                        throws javax.security.sasl.SaslException

Specified by:

buildResponse in class SASLBaseOperationImpl

Throws:

javax.security.sasl.SaslException

toString

public java.lang.String toString()

Overrides:

toString in class SASLBaseOperationImpl

resetInput

protected void resetInput()

readFromBuffer

public void readFromBuffer(java.nio.ByteBuffer b)
                    throws java.io.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:

java.io.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

Throws:

java.io.IOException

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(java.lang.String key,
                 long cas,
                 byte[] val,

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
