public class VersionedPutKeyValueCommand
extends PutKeyValueCommand

A form of PutKeyValueCommand that also applies a version to the entry created. Note that this command is only used during state transfer. Normally versioning requires transactions, and as such it used VersionedPrepareCommand and the regular PutKeyValueCommand.

5.1

Method Detail

getVersion

public EntryVersion getVersion()

setVersion

public void setVersion(EntryVersion version)

perform

public Object perform(InvocationContext ctx)
               throws Throwable

Description copied from interface: ReplicableCommand

Performs the primary function of the command. Please see specific implementation classes for details on what is performed as well as return types. Important: this method will be invoked at the end of interceptors chain. It should never be called directly from a custom interceptor.

Specified by:

perform in interface ReplicableCommand

Overrides:

perform in class PutKeyValueCommand

Parameters:

ctx - invocation context

Returns:

arbitrary return value generated by performing this command

Throws:

Throwable - in the event of problems.

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Specified by:

getCommandId in interface ReplicableCommand

Overrides:

getCommandId in class PutKeyValueCommand

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

getParameters

public Object[] getParameters()

Description copied from interface: ReplicableCommand

Used by marshallers to stream this command across a network

Specified by:

getParameters in interface ReplicableCommand

Overrides:

getParameters in class PutKeyValueCommand

Returns:

an object array of arguments, compatible with pre-2.2.0 MethodCall args.

setParameters

public void setParameters(int commandId,
                 Object[] parameters)

Description copied from interface: ReplicableCommand

Used by the CommandsFactory to create a command from raw data read off a stream.

Specified by:

setParameters in interface ReplicableCommand

Overrides:

setParameters in class PutKeyValueCommand

Parameters:

commandId - command id to set. This is usually unused but *could* be used in the event of a command having multiple IDs, such as PutKeyValueCommand.

parameters - object array of args

toString

public String toString()

Overrides:

toString in class PutKeyValueCommand
