MultiGetOperationImpl

public MultiGetOperationImpl(Collection<String> k,
 OperationCallback cb)

Method Details

addKey

protected int addKey(String k)

Add a key (and return its new opaque value).

initialize

public void initialize()

Description copied from interface: Operation

Initialize this operation. This is used to prepare output byte buffers and stuff.

Specified by:

initialize in interface Operation

Specified by:

initialize in class BaseOperationImpl

finishedPayload

protected void finishedPayload(byte[] pl)
                        throws IOException

Overrides:

finishedPayload in class OperationImpl

Throws:

IOException

opaqueIsValid

protected boolean opaqueIsValid()

Description copied from class: OperationImpl

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.

Overrides:

opaqueIsValid in class OperationImpl

getRetryKeys

public List<String> getRetryKeys()

Returns the keys to redistribute.

Returns:

the keys to retry.

getKeys

Description copied from interface: KeyedOperation

Get the keys requested in this GetOperation.

Specified by:

getKeys in interface KeyedOperation

getNotMyVbucketNodes

public Collection<MemcachedNode> getNotMyVbucketNodes()

Specified by:

getNotMyVbucketNodes in interface VBucketAware

addNotMyVbucketNode

public void addNotMyVbucketNode(MemcachedNode node)

Specified by:

 short vb)

Specified by:

setVBucket in interface VBucketAware

getVBucket

public short getVBucket(String k)
