Constructor & Destructor Documentation

DeferredReply()

DeferredReply ( DeferredContext &  context, ulong  id  )

inline

Constructor.

Parameters

context	Context to use
id	Request ID to use

~DeferredReply()

~DeferredReply ( )

inline

Destructor.

Member Function Documentation

deferred_reply_delete()

void deferred_reply_delete ( bool  success )

inline

Finish delete request and report result.

Parameters

success

Whether successful, false if key not found

deferred_reply_error()

void deferred_reply_error ( const SubString &  msg )

inline

Finish deferred response with an error.

Parameters

msg	Error message to send back to client – must not have any newlines

deferred_reply_get()

void deferred_reply_get ( const SubString &  key, const SubString &  value, uint32  flags, uint64 *  cas_id = NULL  )

inline

Send get request value for key.

• This may be called multiple times, once per requested key
• Keys not found are skipped and don't have a response value
• After last response value call deferred_reply_get_end() to finish the response

Parameters

key	Key for value to send
value	Value to send for key
flags	User flags stored with value
cas_id	Compare-And-Swap ID to send, NULL for none – this must only be non-null for CAS GET request variants, see GetAdvParams

deferred_reply_get_end()

void deferred_reply_get_end ( )

inline

Finish response for get request.

deferred_reply_increment()

void deferred_reply_increment ( UInt64  value )

inline

Finish increment/decrement request and report result.

Parameters

value

Result value after increment/decrement, null if key not found

deferred_reply_store()

void deferred_reply_store ( Memcached::StoreResult  result )

inline

Finish set/store request and report result.

Parameters

result

Command result – see Memcached::StoreResult

deferred_reply_touch()

void deferred_reply_touch ( bool  success )

inline

Finish touch request and report result.

Parameters

success

Whether successful, false if key not found
