NoopOperation noop(OperationCallback cb)
cb
- the operation callback
DeleteOperation delete(String key, OperationCallback operationCallback)

delay
- delay until flush.operationCallback
- the status callback
GetOperation get(String key, GetOperation.Callback callback)
key
- the key to getcallback
- the callback that will contain the results
GetsOperation gets(String key, GetsOperation.Callback callback)
key
- the key to getcallback
- the callback that will contain the results
GetOperation get(Collection<String> keys, GetOperation.Callback cb)
keys
- the collection of keys to getcb
- the callback that will contain the results
MutatorOperation mutate(Mutator m, String key, int by, long def, int exp, OperationCallback cb)
m
- the mutator typekey
- the mutatee keyby
- the amount to increment or decrementdef
- the default valueexp
- expiration in case we need to default (0 if no default)cb
- the status callback
StatsOperation stats(String arg, StatsOperation.Callback cb)
arg
- the stat parameter (see protocol docs)cb
- the stats callback
StoreOperation store(StoreType storeType, String key, int flags, int exp, byte[] data, OperationCallback cb)
storeType
- the type of store operationkey
- the key to storeflags
- the storage flagsexp
- the expiration timedata
- the datacb
- the status callback
ConcatenationOperation cat(ConcatenationType catType, long casId, String key, byte[] data, OperationCallback cb)
catType
- the type of concatenation to perform.key
- the keycasId
- the CAS value for an atomic compare-and-catdata
- the data to storecb
- a callback for reporting the status
CASOperation cas(StoreType t, String key, long casId, int flags, int exp, byte[] data, OperationCallback cb)
key
- the key to storecasId
- the CAS identifier value (from a gets operation)flags
- the storage flagsexp
- the expiration timedata
- the datacb
- the status callback
VersionOperation version(OperationCallback cb)
Collection<Operation> clone(KeyedOperation op)
This is used for requeueing operations after a server is found to be down.
Note that it returns more than one operation because a multi-get could potentially need to be played against a large number of underlying servers. In this case, there's a separate operation for each, and callback façade to reassemble them. It is left up to the operation pipeline to perform whatever optimization is required to turn these back into multi-gets.
op
- the operation to clone
